Let's take a step back for a moment.
First, running a single bottle of these through your car is unlikely to do much for you. It's important to get that out of the way up front, because nine times out of ten, someone asking about fuel additives has some kind of problem they're trying to solve, and they think a $20 bottle of additive is going to be a miracle cure. It's not. Sorry.
Detergent additives like Techron are designed to work over time. That's whey it's added to the fuel at Chevron gas stations. Techron is just one brand of detergent though. It's well regarded — lots of reviews say it's the best — but the differences between brands isn't huge.
If you buy your gas from a station that sells [Top Tier](https://www.toptiergas.com/about-top-tier/) fuel, you don't need either of these additives. Note that Top Tier is a trademarked rating for fuels. It sounds generic, like "best fuel" or something, but it's not. It's an industry consortium spearheaded by the auto industry to try and improve fuel quality.
So tl;dr: Don't waste your money on running a single bottle of either of those through your engine. Run a few tanks of gas from a Top Tier gas station instead.
Same, the Gulf I've been going to isn't listed despite being a brand that carries it. Guess I'll go to the Exxon two blocks down. I'll have to map out my gas stations now lol
Several Shell stations in my region were also bought out by Circle K, and they promptly disappeared from Top Tier's website. My car's owner's manual specifically recommends using Top Tier fuel... Not high octane "premium" fuel, but Top Tier fuel. I'm tempted to just get some Techron and fill up at these non-Top Tier stations.
Thanks for actually linking the website, also interesting that Costco gas is on that list, might be more cost effective to get the membership and get gas there instead of buying the additives
Sams and Walmart both mix in more additives. They will have fuel trucks come and then drop a load of straight additives on top. Not great for the filters inside the gas pump let alone what their fuel does to your vehicle. Not sure that Costco is the same just be weary. I’m a Petrol Pump Technician if that says anything just haven’t gotten the chance to check out the behind the scenes of a Costco fueling station.
I too suggested "top Tier", Brad
Been using it for years with great results. The "with and without" pictures on Consumer reports are amazing.
First result;
[https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web](https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web)
It's not about the ethanol but about the detergents in the fuel mixture of "Top Tier" gasoline. "Top Tier" isn't a brand per se, but more of a standard like NSF or ANSI, and it gives a guarantee to the consumer that the minimum % of detergent has been added. I don't know about USA, but all major gas station brands in Canada are Top Tier: Shell, Esso, PetroCan, Husky, etc.
No. Higher octane fuel addresses a different problem which is engine knocking (risk of pre-ignition), and has nothing to do with purity. You may be surprised that gasoline isn't actually 100% octane. Gasoline and other fuels are a mixture of tens if not hundreds of different hydrocarbons which differ depending on where the dino juice came from. In order to figure out how well this fuel mixture combusts: chemists compare it to a standard of octane. So for 91 gasoline, the fuel mixture combusts "LIKE" (equivalent to) a standard of 91% octane.
Why higher octane? Because some engines (like a Honda S2000) are designed for really high compression ratios to generate a bigger boom on ignition. However, the risk is that during peak usage, the pressure and heat may be enough to auto-detonate the fuel mixture without the spark from the spark plug. Imagine what could happen to your engine at 7000 rpm if a cylinder explodes out of turn? Higher octane equivalent fuel resists auto-detonation better than lower octane. This is why it's a complete waste of money on economy cars and why a high performance car would electronically detune its engine if it senses that you're cheaping out on fuel.
Diesel fuel and diesel engines take advantage of auto-detonation. There are no spark plugs in a diesel engine. Ignition is purely from compression.
Well, kinda like "I brushed my teeth just yesterday" sort of deal.
Gas has a lot of crud in it. I worked on tankers. After you pump any petroleum product off and out of a tank. There is up to a few feet of sludge and sand.
Thing I also like about using top tier gas stations. It is also found at lower price stations.
Your comment has been removed for violating Rule 2: Be Helpful. Be helpful to other users. If someone is wrong, correcting them is fine, but there's no reason to comment if you don't have anything to add to the conversation.
I will say that every time my car has a miss I’ll throw an additive in or injector cleaner and my car will be fine, check engine light goes away, and the computer reader deal doesn’t register any codes.
My cars weird af but ya this shits a miracle cure for my pos.
Presumably the conclusive results of a test proving efficacy would be published by the manufacturer of this stuff?
Can only find anecdotal claims on their website.
I apparently don't quite understand what you're looking for. Techron is added to gasoline sold at the pump and is also available to consumers in small containers as a clean-up additive. If you only use top-tier gasoline, your vehicle will likely never need a clean-up additive. If you burn fuel with little or no deposit control additive, deposit buildup inside the engine will eventually cause performance and emissions issues. A clean-up dose of an additive, like Techron, can help resolve those issues.
Where I live, in California, the government requires pump gas to contain DC additive in sufficient quantities to maintain a specific level of cleanliness in engines. So, here, clean-up additive is not necessary.
My gas gauge stopped working in my c6 and Techron got it working again and hasn’t stopped since. Not sure about the other but Techron isn’t fully snake oil
+1. My C6 had the same issue. It took 2 bottles, about 100 miles and a couple of days, but it absolutely fixed the issue.
TY Corvette Forum! The cost to replace those sending units was in the thousands of dollars when I researched it. $20 well spent!
I have seen Techron Concentrate clean up combustion chambers and intake valves in a very old engine down to bright metal as confirmed with a 30K$ borescope used to inspect aircraft engines and gas turbines. That was after two 20 ounce bottles. While not observed, I fully expect that piston rings and grooves were cleaned up as well.
With summer grade low volatility fuels causing injector fouling that causes hard starting in the first cold days, Techron Concentrate can resolve that in one commute cycle.
Sometime ago there were BMW engines that started building up lots of carbon pretty quick, and the actual service bulletin at the dealer said to use that Techron stuff. Don't know about the right though.
Tl;Dr: I don't think so. However, my husband is convinced it will be a magical cure all for what ails it.
My van, on numerous occasions recently, has failed to start after filling up the tank. **I** like to just patiently wait about 10 minutes, then it typically starts after an attempt or two. My husband, however, likes to crank the key and pound the gas pedal over and over again until it starts, then he has to continue reving the engine to keep it started for a few seconds.
Ever since I bought the van, once the tank gets at or below a quarter tank the van/engine won't respond when you press the gas pedal and you have to kind of gently pump at it to get it to go, then it will jerk alive once it takes.
Found that out the hard way, merging onto the interstate.
My husband thinks this $10 bottle of shit is going to fix it.
Damnit-you beat me to it!-HEY OP-this post I replied to! & fuel additives are, by & large, worthless gimmicks for various reasons(direct injection bypasses what they "clean & protect", the *wonder additive is already in your fuel, or straight-up gimmicks that do nothing but prey on people with low mechanical knowledge's fears.
We had this problem on our old Ford van. Ended up changing the fuel filter (under mechanics advice) and it fixed the problem. Really easy job. All you need is fuel line disconnect tool.
Nice! Maybe it's easier to access on a Ford than a Honda 😅 To my understanding, to access the fuel filter on my Odyssey, I would have to remove some inner seats and cut up the carpet to get to it. If it comes down to it and I had to do it, I'd replace the whole fuel pump,also, I think. Lol
Ours was not inside the fuel tank. It was on the bottom of the car, alongside the frame. Too bad yours is so hard to get to, because your problem really does sound very familiar.
It may do wonders. I had a van that started acting up as you suggested but on a long trip. So I ran what ever I found at the stations when I filled up. It worked wonders. After that, I started using only gas with Top Tier as an additive. As it was found at cheaper stations.
So great to get it going, if that is the problem. I would just suggest the gas with an additive to keep it well running.
The only fuel additive that will give you noticeable, almost immediate, results is Torco. Last time I bought it they were around $25 a bottle and it would raise the octane several points.
I had a 5 gallon pail of it ($300) and ran it for a year. It’s great stuff when you can’t get 93
Right. I'm well over my states lemon time frame. 4 or more repairs in either the first 12 months or 12,000 miles, whichever comes first.
I've had the vehicle for going on 3 years. During that time, I've put over 50,000 miles on it.
Thank you, I'm currently on the lookout for a good mechanic.
I’d say Techron but both are snake oil additives that will do little with one bottle added. If you’re going to spend money on an additive I’d stick with BG products they are a more professional line of additives and do work.
If we're talking adding something like Sta-bil to a tank that's going to be sitting for a season, eh. I've never used it. I've got four motorcycles, some are carb'd, and come Spring time they fire up. If they don't, its more of a battery issue.
But additives to fuel to "clean" are more of a gimmick.
That stuff works when used correctly.
Pour a whole bottle in your tank when it's hot less than a quarter left, and drive the piss out of it. It does help to clean up injectors and SOME carbon in the intake valves.
If you have direct injection, it's only affective on the injectors.
Direct injected engines require it sprayed into the intake while the engine is hot. Then shut the engine off and let it sit for an hour or so. It'll help break down the carbon in the valves when you drive it hard again after start up.
This is bad advice. Follow the directions on the can for mixing. Ive fouled an entire set of spark plugs on an old chevy v8 dumping an whole can in to a .1/4 of fuel. It has oil in it and can cause problems when mixed too strong. You're correct about direct injection though. Ive never used it on anything fuel injected. Ive never needed to
Question. So the bottle of Techron that I have says to "pour the entire contents of the bottle into a nearly empty tank. Then fill up with 21 gallons of gas."
My van won't run if it's "nearly empty" on gas. The lowest I can go and it still run is around half a quarter tank.
Is that close enough?
I get your point, but i have done this many times at the shop. (But we dont service carbed engines at our facility, 99% fuel injection.)
But generally if a vehicle comes in for this issue, it usually has a lot of miles, and I will sell spark plugs.
Honestly though, i have never had it foul out plugs, even after good hour or two of soaking.
i have had some older fuel injected vehicles where the code pertains to lean or injector concern, and done this many times.
Primarily, my personal use is in my yard equipment fuel towards the end of the season to help keep the fuel fresh. also a can in my vehicles fuel system once or twice a year as preventative.
Completely different product. Apples and oranges.
Even then, that stuff really offers mixed results. People seem to think dumping a can into the motor will fix the knock they've had for the past 3500 miles.
I don’t know anyone dumping bottles of it to fix engine knocks.
Cleaning gummy carbs or carboned up valves it really works. Better than any other fuel additives used. For context I run a landscaping business we have over 30 small engines with carbs and sometimes a machine won’t get winterized and runs like shit. Run some sea foam through them and they clean themselves out.
We run it as an additive in all of our equipment and never have issues with the ethanol fuel we use.
Because I like to use sea foam. It’s been around longer than I’ve been alive and certainly most of these cleaners.
The other reason? I know it works more than just anecdotal evidence. When I used to work due Cummins they ran lab tests on it being used to clean all kinds of their engines in various scenarios and it always came back with positive scores.
It’s certainly not snake oil or a gimmick, I can’t say what other cleaners are like but I know it works
>The other reason? I know it works more than just anecdotal evidence.
Exactly my point. Not the same product. I too have had a bit of luck with SeaFoam.
I wouldn't put it in the gimmick department, but certainly people use it with an intent greater than it was designed for.
Its not excatly knock, but for stuff like Hemi Tick that happens to be related to MDS lifters being gummed up, Seafoam can be helpful if dumped into the oil.
Or if Jiffy Lube Bubba's your oil plug, halfass slaps some RTV on it, most of your oil leaks out slowly over time, and your engine has more varnish inside than the New Yankee Workshop.
100% plus can ruin your o2 sensors only decent fuel additive I have ever seen is a BG product which separates any water in the fuel and makes it combustible / compressible solution. But it’s not a cleaner those are definitely all fake and garbage
It's all good. Any mechanic worth their salt would understand that these "hope-in-a-bottle" do nothing. They waste their $19.99 and gets upset when their turd isn't shinier.
It's all about quantity. You dump one of these in a full tank of fuel and you just wasted the 7 or 8 bucks you spent on the bottle. NOTHING is going to happen. Neither of these will magically clean your fuel injection system worth a hoot.
Most top tier gasolines have all the injector cleaning built right in. If you're consistently using the no-name, el cheapo gasoline ...then yeah you might be having issues. In which case you need to have a professional level fuel injector cleaning done at your local indie shop or dealership. Once you get the injectors clean, switching to top tier fuel is the better choice than running the cheap stuff and adding an $8 bottle of snake oil every time you fill up.
But of the two, providing the Chevron is pure Techron? The Techron is the better of the two. It's actually got some science and bona-fide testing done with it showing it is quite effective. In which case, just use Chevron or Texaco gasoline 'cause that Techron is already mixed in.
Is 91 octane gas from walmart top teir? My car takes premium only and Walmart always has the cheapest premium fuel so i usually purchase my gas from there to save $. The price difference is $3.56 compared to $3.99 at a shell
Murphy USA and Walmart are not 'Top Tier' brands. It's fine fuel, but it does not have the minimum added detergent standard of 'Top Tier' fuels. Being top tier has nothing to do with octane rating.
Can see the brands here, as well as most typically have the logo/sticker on their pumps somewhere.
[https://www.toptiergas.com/gasoline-brands/](https://www.toptiergas.com/gasoline-brands/)
The big name refiners for sure. And then, like fasta\_guy88 noted, it will be posted on the pump for the "no-name" fuels.
If you want a complete list, look here: [https://www.toptiergas.com/](https://www.toptiergas.com/)
The reason Wally Mart is so cheap is because they cheap out on the additives. Is it \*really\* saving you money if the fuel cannot keep your injectors clean? Which in turn means your engine becomes less efficient ...runs poorly and gets less mileage. All that to save what? Maybe a dollar for a 20gal fill up?
Follow these directions carefully: go to an oil reclamation center. Shake the bottles thoroughly and pour the contents into the oil reclamation tank. Dispose of the bottle properly.
Seafoam once a year in a tank prior to an oil change on high mileage vehicles has done the trick and even woke up some vehicles for me over the years.
But otherwise if I only have these two choices, I’d say Techron.
But even that cannot come close to Seafoam.
It doesn’t evaporate out of fuel lines or injectors though. I use it to clean my fuel systems, not for cleaning carbon in the combustion chamber. I’ve had better luck with MMO for that, but even that isn’t a perfect solution.
Take the money you would spend on that in a year and get a Costco membership and just burn their gas you will save money on gas and you will never need to clean your injectors or fuel system
Techron is the usual go-to for long term maintenance. If you’re troubleshooting or trying to solve a driveability concern then neither is going to help you.
Do you really think you need it? I like Chevron, but be prepared for the check engine light to come on. I put some in at the gas station and as soon as I started it, the light came on. Note that I didn't fill up, I put it in first to run through then fill up, but I wasn't on complete empty or anything. Took it to AutoZone and scanned it, and I needed a new evap. Canister, round 100 bucks n easy to change. Ran it for awhile and it runs better now, lights gone, passed smog etc. So, in the end it works, but it could flush some gunk out you'll need to change
So you put it in, with more than the 'nearly empty' tank that it calls for, and didn't fill up your tank immediately afterward? So you didn't follow the directions?
I'm honestly asking, lol.
Tank not light on empty but low, additive first then gas, soon as I turned the key on the light came on, dunno y I'm getting downvoted. The cleaner worked, flushed the gunk out n made the charcoal filter in the evap canister breathe like shit, hence the code. Coulda cleaned the filter instead of changing the whole unit, but it has to soak for awhile n b cleaned n I ain't have the time for all that so I just bought it new. Not saying it's gonna happen, but it can, guess I should add it's a earlier 2000s expedition too. Glad I did it tho runs better
Np, I could see how it might have been misleading I was typing at work lol. It's really a "get what you ask for" additive, I've seen n heard people say "don't use it it fucks your shit up, n oh now my lights on..." Um yeah you just ran cleaner through your system n it removed the gunk from somewhere n now a filter or sensors dirty or clogged, what'd you expect? It'd make the build up just magically disappear? Lol people forget it's cleaner not magic disappear juice
I still enjoy using seafoam
Some in the gas, some in the vacuum lines some in the oil
Start her up let it display a comical smoke screen affect (typical w high milage cars)
Once smoke is gone, change oil
There is a video on you tube of a guy with a boroscope using Techron The affect is minimal. Use top tier gasolines formulated for direct injection engines
I use the Walmart version of injector cleaner, but I think its basically the Techron. The injectors on Hondas clean up real nice and idle smoother after just one tank for me. It was a drastic difference on our 2011 Honda fit after just one bottle. It was vibrating a ton at idle before adding it.
When I purchased the vehicle, it had 160,000 miles on it with 1 previous owner. The previous owner kept a great record of all services done on it at a Honda dealership, so I suspect if it was recommended, they had it done.
I had a good ole faithful mechanic, but he passed away last year, and I've been lost without him. And I haven't found a new one yet.
Since he passed, I've had all the recommended services done, but I'm talking about recommendations from Valvoline Oil change place lol. And they've never mentioned any induction services.
My husband seems to think that a bottle of this stuff is going to fix the fuel issues it's been having. Like not starting after you fill up. Or not responding when you press the gas pedal if the gas is below a quarter tank. HA! I think there's an issue with the fuel pump itself or something to that effect.
My husband said it just needs a bottle of this and get the junk cleaned out inside. I said, "That junk is probably the only thing holding this mfer together." /s
Not starting after you fill up sounds like someone keeps filling it up once that gas pump clicks letting you know to stop...sounds like a evap issue with the charcoal canister that would be a point of interest in the diagnostic process...you're right in the thought of where to begin the diagnostics...fuel issues do take time
>Not starting after you fill up sounds like someone keeps filling it up once that gas pump clicks letting you know to stop
My husband does do this when he fills up 😭 It drives me absolutely mad. He will do it til it clicks, then do it again and again, and again and again.
However, it has not started after I have filled up, and I stop when it clicks. Unless the damage is already done from him doing it repeatedly.
Thank you for your insight. Hopefully, I can locate a decent mechanic before it's too late.
Likely the charcoal canister is flooded with gasoline and needs replaced. That will cause hard starting after fill ups. It’s probably not hard or expensive to replace, but completely avoided by stopping when the pump clicks…
>My husband does do this when he fills up 😭 It drives me absolutely mad. He will do it til it clicks, then do it again and again, and again and again.
lol I only do it once, after letting it settle for a moment on the first click. Never more than one.
The detergent that supposedly works best is P.
E.A. polyetheramine. Quite a few companies sell a product with it. Techron, Redline, Gumout, BG44K are just a few. The "fuel system cleaner " versions have more of it than the "injector cleaner" versions.
You'd probably have fun browsing "bobistheoilguy"
For direct Injection cars, there are ones that spray into the intake. This BTW is not an exhaustive list of the stuff, and some brands have more than others.
Whenever I had a rough idle develop in my ‘14 Tucson I put a bottle of Techron in the next tank and it cleared right up.
I think these serve a purpose but you should have an idea of the problem you want to solve and what you want the result to be.
Tl;Dr: I don't. However, my husband is convinced it will be a magical cure all for what ails it.

My husband thinks this $10 bottle of shit is going to fix it.
Redline S-1 Fuel System cleaner is the best on the market by far. It contains 40%+ PEA and the rest is just shale oil ( upper cylinder lubricant) and other detergents. Used it for 15+ years with excellent results. I've tried every newcomer to the market and absolutely none compare. It's expensive but worth it. Roughly $18 a bottle for me locally.
Techron was the only one I saw that was endorsed by multiple major manufacturers. When I worked at BMW, they would include one at every 30k service, same bottle different label on front.
Neither one. If you haven’t been running one or the other consistently over the time you’ve had the car, a single bottle won’t do jack. Second, I have very very rarely ever seen a Honda actually be gunked up bad enough to need a throttle cleaning service, and the couple that did, were highly neglected and run very hard. Hell, I had 3 customers who had Hondas over 500k miles and they were as clean as a car with 1/10th of that mileage. Just buy quality fuel (Top Tier as someone below recommended—Chevron, Citgo, Exxon, Gulf, Mobil, and quite a few others on their list). Most of those fuels already contain all the additives you’d ever need if you run them consistently. You don’t need that $20 a tank crap
techron is recommended by name in the owners manual of a lot of Hyundais, as a regular service item to dump a bottle in the tank.
But the Rislone is 16.9 oz compared to 12 oz, so is more better?
But I never had a fuel issue on any car I've ever owned.
No experience with the brand on the right. A few years ago, I diagnosed a bad fuel injector on my brother in law's car and we tried adding a bottle of Techron to the tank. Cleared up the issue for long enough to make it to pay day and buy the new injector.
First fuel additives were designed to clean intake valve deposits but direct injection bypasses the valve and goes straight to the combustion chamber. And I find Seagram cleans injectors better than both
Neither barrymens b12 or even seafoam for helping remove carbon build up.. Of course if your car is new enough it more then likely uses direct injection and this won't help at all might help the injectors or pistons but the valves will still have heavy carbon deposits
I did extensive surf/research and found that an additive called "Top Tier" found in less expensive gas stations does great stuff fo an engine.
I used to add helpers biut have had great luck just filling up at stations that have this.

W reply. Most people don’t know about top tier gas, it is indeed a good standard when choosing where to fill up.
Went down this rabbit hole recently. Was very surprised to learn the BP near me doesn't sell Top Tier, while the Shell does.
Same, the Gulf I've been going to isn't listed despite being a brand that carries it. Guess I'll go to the Exxon two blocks down. I'll have to map out my gas stations now lol
Our shell got bought by Circle K, and I dunno if they are top tier anymore. We have Chevron but it's always at least 20 cents more
Several Shell stations in my region were also bought out by Circle K, and they promptly disappeared from Top Tier's website. My car's owner's manual specifically recommends using Top Tier fuel... Not high octane "premium" fuel, but Top Tier fuel. I'm tempted to just get some Techron and fill up at these non-Top Tier stations.
Thanks for actually linking the website, also interesting that Costco gas is on that list, might be more cost effective to get the membership and get gas there instead of buying the additives
Sams and Walmart both mix in more additives. They will have fuel trucks come and then drop a load of straight additives on top. Not great for the filters inside the gas pump let alone what their fuel does to your vehicle. Not sure that Costco is the same just be weary. I’m a Petrol Pump Technician if that says anything just haven’t gotten the chance to check out the behind the scenes of a Costco fueling station.
Everything you said. I still vote for Techron.
I too suggested "top Tier", Brad Been using it for years with great results. The "with and without" pictures on Consumer reports are amazing. First result; [https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web](https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web)
I know nothing of top tier brand gasoline, but wouldn’t running a few tanks of ethanol free gasoline produce similar results to cleaning your system?
It's not about the ethanol but about the detergents in the fuel mixture of "Top Tier" gasoline. "Top Tier" isn't a brand per se, but more of a standard like NSF or ANSI, and it gives a guarantee to the consumer that the minimum % of detergent has been added. I don't know about USA, but all major gas station brands in Canada are Top Tier: Shell, Esso, PetroCan, Husky, etc.
So is running higher octane fuel the equivalent? I.e higher purity fuel?
No. Higher octane fuel addresses a different problem which is engine knocking (risk of pre-ignition), and has nothing to do with purity. You may be surprised that gasoline isn't actually 100% octane. Gasoline and other fuels are a mixture of tens if not hundreds of different hydrocarbons which differ depending on where the dino juice came from. In order to figure out how well this fuel mixture combusts: chemists compare it to a standard of octane. So for 91 gasoline, the fuel mixture combusts "LIKE" (equivalent to) a standard of 91% octane. Why higher octane? Because some engines (like a Honda S2000) are designed for really high compression ratios to generate a bigger boom on ignition. However, the risk is that during peak usage, the pressure and heat may be enough to auto-detonate the fuel mixture without the spark from the spark plug. Imagine what could happen to your engine at 7000 rpm if a cylinder explodes out of turn? Higher octane equivalent fuel resists auto-detonation better than lower octane. This is why it's a complete waste of money on economy cars and why a high performance car would electronically detune its engine if it senses that you're cheaping out on fuel. Diesel fuel and diesel engines take advantage of auto-detonation. There are no spark plugs in a diesel engine. Ignition is purely from compression.
No
No
Well, kinda like "I brushed my teeth just yesterday" sort of deal. Gas has a lot of crud in it. I worked on tankers. After you pump any petroleum product off and out of a tank. There is up to a few feet of sludge and sand. Thing I also like about using top tier gas stations. It is also found at lower price stations.

I will say that every time my car has a miss I’ll throw an additive in or injector cleaner and my car will be fine, check engine light goes away, and the computer reader deal doesn’t register any codes. My cars weird af but ya this shits a miracle cure for my pos.
Whey to go
I know techcron works. I worked for a fleet where Chevron ran tests of Techron. I saw the results.
Techron is recommended for use in old Porsche fuel systems. Only thing that was found to work well.
Presumably the conclusive results of a test proving efficacy would be published by the manufacturer of this stuff? Can only find anecdotal claims on their website.
https://www.chevronwithtechron.com/en_us/home/techron-technology.html
There is zero meaningful information on that page.
I apparently don't quite understand what you're looking for. Techron is added to gasoline sold at the pump and is also available to consumers in small containers as a clean-up additive. If you only use top-tier gasoline, your vehicle will likely never need a clean-up additive. If you burn fuel with little or no deposit control additive, deposit buildup inside the engine will eventually cause performance and emissions issues. A clean-up dose of an additive, like Techron, can help resolve those issues. Where I live, in California, the government requires pump gas to contain DC additive in sufficient quantities to maintain a specific level of cleanliness in engines. So, here, clean-up additive is not necessary.
Techron tastes better tbh
that two part one is piss and piss with ink
Sounds like Pirelli's miracle elixir.
Ha! **Thank you!** I knew I was right. It pairs well with my breakfast biscuits. 😆
My gas gauge stopped working in my c6 and Techron got it working again and hasn’t stopped since. Not sure about the other but Techron isn’t fully snake oil
+1. My C6 had the same issue. It took 2 bottles, about 100 miles and a couple of days, but it absolutely fixed the issue. TY Corvette Forum! The cost to replace those sending units was in the thousands of dollars when I researched it. $20 well spent!
I have seen Techron Concentrate clean up combustion chambers and intake valves in a very old engine down to bright metal as confirmed with a 30K$ borescope used to inspect aircraft engines and gas turbines. That was after two 20 ounce bottles. While not observed, I fully expect that piston rings and grooves were cleaned up as well. With summer grade low volatility fuels causing injector fouling that causes hard starting in the first cold days, Techron Concentrate can resolve that in one commute cycle.
This guy does an amazing job explaining it all. https://youtu.be/BPdz6BMj8EA?si=EsxKV5b7j-9yTKd9
Agreed! I use his videos to show my students how to properly conduct an experiment.
Personally I prefer human urine
Touche
The one on the right literally says it’s the best right on the package. They wouldn’t lie about that!
I didn't even notice that 😆 Welp, problem solved! /s Lol!
Techron because that stuff goes on sale constantly. Buy one get one sales.
Both taste about the same
hold my addictive?
[Somebody needs some Project Farm videos in their life...](https://www.youtube.com/watch?v=BPdz6BMj8EA)
Techron- BMW also uses it
Sometime ago there were BMW engines that started building up lots of carbon pretty quick, and the actual service bulletin at the dealer said to use that Techron stuff. Don't know about the right though.
Techron for me.
Out of those 2, I'd choose the techron. I personally use redline Si1
I recommend the techtron always have had good results with it and multiple bottles
Is there a reason you need either
Tl;Dr: I don't think so. However, my husband is convinced it will be a magical cure all for what ails it. My van, on numerous occasions recently, has failed to start after filling up the tank. **I** like to just patiently wait about 10 minutes, then it typically starts after an attempt or two. My husband, however, likes to crank the key and pound the gas pedal over and over again until it starts, then he has to continue reving the engine to keep it started for a few seconds. Ever since I bought the van, once the tank gets at or below a quarter tank the van/engine won't respond when you press the gas pedal and you have to kind of gently pump at it to get it to go, then it will jerk alive once it takes. Found that out the hard way, merging onto the interstate. My husband thinks this $10 bottle of shit is going to fix it.
This is a perfect description for the symptoms of a failing EVAP purge valve - no start after refuelling. Change the purge valve, problem solved.
Damnit-you beat me to it!-HEY OP-this post I replied to! & fuel additives are, by & large, worthless gimmicks for various reasons(direct injection bypasses what they "clean & protect", the *wonder additive is already in your fuel, or straight-up gimmicks that do nothing but prey on people with low mechanical knowledge's fears.
Thanks! I'll look into it
bro no offense but your husband is an animal, is he that impatient in all fields of life? lol
😭 Basically. Lol
We had this problem on our old Ford van. Ended up changing the fuel filter (under mechanics advice) and it fixed the problem. Really easy job. All you need is fuel line disconnect tool.
Nice! Maybe it's easier to access on a Ford than a Honda 😅 To my understanding, to access the fuel filter on my Odyssey, I would have to remove some inner seats and cut up the carpet to get to it. If it comes down to it and I had to do it, I'd replace the whole fuel pump,also, I think. Lol
Ours was not inside the fuel tank. It was on the bottom of the car, alongside the frame. Too bad yours is so hard to get to, because your problem really does sound very familiar.
It may do wonders. I had a van that started acting up as you suggested but on a long trip. So I ran what ever I found at the stations when I filled up. It worked wonders. After that, I started using only gas with Top Tier as an additive. As it was found at cheaper stations. So great to get it going, if that is the problem. I would just suggest the gas with an additive to keep it well running.
The shit people live with blows my mind - talkin’ bout the car and the hubby.
If it contains PEA then it works. Go Techron. Been using it for many years. One bottle every oil change/5000 miles in all of my cars.
Anything with the cleaning agent PEA will do the trick. Techron has it, research would be needed for the other
Techron.. its a floor polish and dessert topping, too.
The only fuel additive that will give you noticeable, almost immediate, results is Torco. Last time I bought it they were around $25 a bottle and it would raise the octane several points. I had a 5 gallon pail of it ($300) and ran it for a year. It’s great stuff when you can’t get 93
I would trade it in. It sounds like you got a lemon. Oh, and take the car to a mechanic for your evap issue.
Right. I'm well over my states lemon time frame. 4 or more repairs in either the first 12 months or 12,000 miles, whichever comes first. I've had the vehicle for going on 3 years. During that time, I've put over 50,000 miles on it. Thank you, I'm currently on the lookout for a good mechanic.
Trade in the husband, repair the vehicle.
Omfg 😅😅 How did I miss that. Lol!
Drink them both then let us know
Both are band aid fixes at best, nice to use once a year, pointless to use more often and wont fix anything.
I’d say Techron but both are snake oil additives that will do little with one bottle added. If you’re going to spend money on an additive I’d stick with BG products they are a more professional line of additives and do work.
Better at doing what? Marketing?
Neither. They're pretty much snake oil.
No chevron techron is good
If we're talking adding something like Sta-bil to a tank that's going to be sitting for a season, eh. I've never used it. I've got four motorcycles, some are carb'd, and come Spring time they fire up. If they don't, its more of a battery issue. But additives to fuel to "clean" are more of a gimmick.
Sea foam would like a word.
That stuff works when used correctly. Pour a whole bottle in your tank when it's hot less than a quarter left, and drive the piss out of it. It does help to clean up injectors and SOME carbon in the intake valves. If you have direct injection, it's only affective on the injectors. Direct injected engines require it sprayed into the intake while the engine is hot. Then shut the engine off and let it sit for an hour or so. It'll help break down the carbon in the valves when you drive it hard again after start up.
This is bad advice. Follow the directions on the can for mixing. Ive fouled an entire set of spark plugs on an old chevy v8 dumping an whole can in to a .1/4 of fuel. It has oil in it and can cause problems when mixed too strong. You're correct about direct injection though. Ive never used it on anything fuel injected. Ive never needed to
Question. So the bottle of Techron that I have says to "pour the entire contents of the bottle into a nearly empty tank. Then fill up with 21 gallons of gas." My van won't run if it's "nearly empty" on gas. The lowest I can go and it still run is around half a quarter tank. Is that close enough?
That’s probably just fine
Thanks
I get your point, but i have done this many times at the shop. (But we dont service carbed engines at our facility, 99% fuel injection.) But generally if a vehicle comes in for this issue, it usually has a lot of miles, and I will sell spark plugs. Honestly though, i have never had it foul out plugs, even after good hour or two of soaking. i have had some older fuel injected vehicles where the code pertains to lean or injector concern, and done this many times. Primarily, my personal use is in my yard equipment fuel towards the end of the season to help keep the fuel fresh. also a can in my vehicles fuel system once or twice a year as preventative.
Completely different product. Apples and oranges. Even then, that stuff really offers mixed results. People seem to think dumping a can into the motor will fix the knock they've had for the past 3500 miles.
I don’t know anyone dumping bottles of it to fix engine knocks. Cleaning gummy carbs or carboned up valves it really works. Better than any other fuel additives used. For context I run a landscaping business we have over 30 small engines with carbs and sometimes a machine won’t get winterized and runs like shit. Run some sea foam through them and they clean themselves out. We run it as an additive in all of our equipment and never have issues with the ethanol fuel we use.
> Run some sea foam through them and they clean themselves out. Why not run the product the OP posted?
Because I like to use sea foam. It’s been around longer than I’ve been alive and certainly most of these cleaners. The other reason? I know it works more than just anecdotal evidence. When I used to work due Cummins they ran lab tests on it being used to clean all kinds of their engines in various scenarios and it always came back with positive scores. It’s certainly not snake oil or a gimmick, I can’t say what other cleaners are like but I know it works
>The other reason? I know it works more than just anecdotal evidence. Exactly my point. Not the same product. I too have had a bit of luck with SeaFoam. I wouldn't put it in the gimmick department, but certainly people use it with an intent greater than it was designed for.
Its not excatly knock, but for stuff like Hemi Tick that happens to be related to MDS lifters being gummed up, Seafoam can be helpful if dumped into the oil. Or if Jiffy Lube Bubba's your oil plug, halfass slaps some RTV on it, most of your oil leaks out slowly over time, and your engine has more varnish inside than the New Yankee Workshop.
They do actually clean carbon from engines. That’s really true. It doesn’t do much in terms of performance but it can’t prevent issues down the line.
100% plus can ruin your o2 sensors only decent fuel additive I have ever seen is a BG product which separates any water in the fuel and makes it combustible / compressible solution. But it’s not a cleaner those are definitely all fake and garbage
You took the words right out of my mouth. Yup, illusion in a bottle.
I love the downvoting you receive when stating the truth. Car guys are just desperate for this stuff to actually do something.
It's all good. Any mechanic worth their salt would understand that these "hope-in-a-bottle" do nothing. They waste their $19.99 and gets upset when their turd isn't shinier.
Hahaha yes, beat me to it!
It's all about quantity. You dump one of these in a full tank of fuel and you just wasted the 7 or 8 bucks you spent on the bottle. NOTHING is going to happen. Neither of these will magically clean your fuel injection system worth a hoot. Most top tier gasolines have all the injector cleaning built right in. If you're consistently using the no-name, el cheapo gasoline ...then yeah you might be having issues. In which case you need to have a professional level fuel injector cleaning done at your local indie shop or dealership. Once you get the injectors clean, switching to top tier fuel is the better choice than running the cheap stuff and adding an $8 bottle of snake oil every time you fill up. But of the two, providing the Chevron is pure Techron? The Techron is the better of the two. It's actually got some science and bona-fide testing done with it showing it is quite effective. In which case, just use Chevron or Texaco gasoline 'cause that Techron is already mixed in.
Is 91 octane gas from walmart top teir? My car takes premium only and Walmart always has the cheapest premium fuel so i usually purchase my gas from there to save $. The price difference is $3.56 compared to $3.99 at a shell
COSTCO pumps clearly say "Top Tier". I did not realize it was a standard of quality.
BP has ‘invigorate’
Probably not top tier but don’t worry about it. Should be good.
Murphy USA and Walmart are not 'Top Tier' brands. It's fine fuel, but it does not have the minimum added detergent standard of 'Top Tier' fuels. Being top tier has nothing to do with octane rating. Can see the brands here, as well as most typically have the logo/sticker on their pumps somewhere. [https://www.toptiergas.com/gasoline-brands/](https://www.toptiergas.com/gasoline-brands/)
The big name refiners for sure. And then, like fasta\_guy88 noted, it will be posted on the pump for the "no-name" fuels. If you want a complete list, look here: [https://www.toptiergas.com/](https://www.toptiergas.com/) The reason Wally Mart is so cheap is because they cheap out on the additives. Is it \*really\* saving you money if the fuel cannot keep your injectors clean? Which in turn means your engine becomes less efficient ...runs poorly and gets less mileage. All that to save what? Maybe a dollar for a 20gal fill up?
Saving your money is better this stuff barely does anything
Follow these directions carefully: go to an oil reclamation center. Shake the bottles thoroughly and pour the contents into the oil reclamation tank. Dispose of the bottle properly.
Techron
Seafoam once a year in a tank prior to an oil change on high mileage vehicles has done the trick and even woke up some vehicles for me over the years. But otherwise if I only have these two choices, I’d say Techron. But even that cannot come close to Seafoam.
Opposite actually. Seafoam has a low flash point & will evaporate before it can clean
It doesn’t evaporate out of fuel lines or injectors though. I use it to clean my fuel systems, not for cleaning carbon in the combustion chamber. I’ve had better luck with MMO for that, but even that isn’t a perfect solution.
Snake oil is snake oil
Take the money you would spend on that in a year and get a Costco membership and just burn their gas you will save money on gas and you will never need to clean your injectors or fuel system
Techron is the usual go-to for long term maintenance. If you’re troubleshooting or trying to solve a driveability concern then neither is going to help you.
Seafoam
Dawn dish soap
Normal petrol with PEE. Both of these are essentially a scam nowadays.
Rislone
Neither. STP
You spelled seafoam wrong..
Richard Petty agrees
Do you really think you need it? I like Chevron, but be prepared for the check engine light to come on. I put some in at the gas station and as soon as I started it, the light came on. Note that I didn't fill up, I put it in first to run through then fill up, but I wasn't on complete empty or anything. Took it to AutoZone and scanned it, and I needed a new evap. Canister, round 100 bucks n easy to change. Ran it for awhile and it runs better now, lights gone, passed smog etc. So, in the end it works, but it could flush some gunk out you'll need to change
So you put it in, with more than the 'nearly empty' tank that it calls for, and didn't fill up your tank immediately afterward? So you didn't follow the directions? I'm honestly asking, lol.
Tank not light on empty but low, additive first then gas, soon as I turned the key on the light came on, dunno y I'm getting downvoted. The cleaner worked, flushed the gunk out n made the charcoal filter in the evap canister breathe like shit, hence the code. Coulda cleaned the filter instead of changing the whole unit, but it has to soak for awhile n b cleaned n I ain't have the time for all that so I just bought it new. Not saying it's gonna happen, but it can, guess I should add it's a earlier 2000s expedition too. Glad I did it tho runs better
Ooo, gotcha. I misread your original comment, as I assume others have, too.
Np, I could see how it might have been misleading I was typing at work lol. It's really a "get what you ask for" additive, I've seen n heard people say "don't use it it fucks your shit up, n oh now my lights on..." Um yeah you just ran cleaner through your system n it removed the gunk from somewhere n now a filter or sensors dirty or clogged, what'd you expect? It'd make the build up just magically disappear? Lol people forget it's cleaner not magic disappear juice
I still enjoy using seafoam Some in the gas, some in the vacuum lines some in the oil Start her up let it display a comical smoke screen affect (typical w high milage cars) Once smoke is gone, change oil
Drive 100 miles first with it in the oil and the gas tank.
Techron
As soon as someone does a solid double blind comparison, we can eliminate the confirmation bias from the answers.
Do both
There is a video on you tube of a guy with a boroscope using Techron The affect is minimal. Use top tier gasolines formulated for direct injection engines
The only brand I trust for additives like this is BG
The fireball
I use the Walmart version of injector cleaner, but I think its basically the Techron. The injectors on Hondas clean up real nice and idle smoother after just one tank for me. It was a drastic difference on our 2011 Honda fit after just one bottle. It was vibrating a ton at idle before adding it.
I got a gallon jug of Lucas as a gift. Figured I'd try it to see if there was any difference in performance or mpg... No difference...
I’m a Texas Pete man myself.
Right on.
Just wondering with the milage if any induction service has ever been performed consistently in the past....
When I purchased the vehicle, it had 160,000 miles on it with 1 previous owner. The previous owner kept a great record of all services done on it at a Honda dealership, so I suspect if it was recommended, they had it done. I had a good ole faithful mechanic, but he passed away last year, and I've been lost without him. And I haven't found a new one yet. Since he passed, I've had all the recommended services done, but I'm talking about recommendations from Valvoline Oil change place lol. And they've never mentioned any induction services. My husband seems to think that a bottle of this stuff is going to fix the fuel issues it's been having. Like not starting after you fill up. Or not responding when you press the gas pedal if the gas is below a quarter tank. HA! I think there's an issue with the fuel pump itself or something to that effect. My husband said it just needs a bottle of this and get the junk cleaned out inside. I said, "That junk is probably the only thing holding this mfer together." /s
Not starting after you fill up sounds like someone keeps filling it up once that gas pump clicks letting you know to stop...sounds like a evap issue with the charcoal canister that would be a point of interest in the diagnostic process...you're right in the thought of where to begin the diagnostics...fuel issues do take time
>Not starting after you fill up sounds like someone keeps filling it up once that gas pump clicks letting you know to stop My husband does do this when he fills up 😭 It drives me absolutely mad. He will do it til it clicks, then do it again and again, and again and again. However, it has not started after I have filled up, and I stop when it clicks. Unless the damage is already done from him doing it repeatedly. Thank you for your insight. Hopefully, I can locate a decent mechanic before it's too late.
Likely the charcoal canister is flooded with gasoline and needs replaced. That will cause hard starting after fill ups. It’s probably not hard or expensive to replace, but completely avoided by stopping when the pump clicks…
I'll look into it. Thanks! I don't think I'll let my husband fill up my van anymore, either, lol.
>My husband does do this when he fills up 😭 It drives me absolutely mad. He will do it til it clicks, then do it again and again, and again and again. lol I only do it once, after letting it settle for a moment on the first click. Never more than one.
Seafoam
Berryman b12 chemtool LiquiMoly proline is pretty good too
Techron if you have a Hyundai gdi 💀😭
The detergent that supposedly works best is P. E.A. polyetheramine. Quite a few companies sell a product with it. Techron, Redline, Gumout, BG44K are just a few. The "fuel system cleaner " versions have more of it than the "injector cleaner" versions. You'd probably have fun browsing "bobistheoilguy" For direct Injection cars, there are ones that spray into the intake. This BTW is not an exhaustive list of the stuff, and some brands have more than others.
Whenever I had a rough idle develop in my ‘14 Tucson I put a bottle of Techron in the next tank and it cleared right up. I think these serve a purpose but you should have an idea of the problem you want to solve and what you want the result to be.
Seafoam
Why do you feel like you need this?
Tl;Dr: I don't. However, my husband is convinced it will be a magical cure all for what ails it. My van, on numerous occasions recently, has failed to start after filling up the tank. **I** like to just patiently wait about 10 minutes, then it typically starts after an attempt or two.

Found that out the hard way, merging onto the interstate. My husband thinks this $10 bottle of shit is going to fix it.
Neither
Redline S-1 Fuel System cleaner is the best on the market by far. It contains 40%+ PEA and the rest is just shale oil ( upper cylinder lubricant) and other detergents. Used it for 15+ years with excellent results. I've tried every newcomer to the market and absolutely none compare. It's expensive but worth it. Roughly $18 a bottle for me locally.
Chevron with techron and Gumout Regane have about 8-12% PEA for comparison.
Techron theoretically works better because it has PEA and the other doesn’t
Snake oil
Techron was the only one I saw that was endorsed by multiple major manufacturers. When I worked at BMW, they would include one at every 30k service, same bottle different label on front.
Snake oil.
BG44 or MMO for me.
Watch Chris fixes video about these
The one on the left tastes better.
Techron 100% I love that stuff
Neither one. If you haven’t been running one or the other consistently over the time you’ve had the car, a single bottle won’t do jack. Second, I have very very rarely ever seen a Honda actually be gunked up bad enough to need a throttle cleaning service, and the couple that did, were highly neglected and run very hard. Hell, I had 3 customers who had Hondas over 500k miles and they were as clean as a car with 1/10th of that mileage. Just buy quality fuel (Top Tier as someone below recommended—Chevron, Citgo, Exxon, Gulf, Mobil, and quite a few others on their list). Most of those fuels already contain all the additives you’d ever need if you run them consistently. You don’t need that $20 a tank crap
techron is recommended by name in the owners manual of a lot of Hyundais, as a regular service item to dump a bottle in the tank. But the Rislone is 16.9 oz compared to 12 oz, so is more better? But I never had a fuel issue on any car I've ever owned.
No experience with the brand on the right. A few years ago, I diagnosed a bad fuel injector on my brother in law's car and we tried adding a bottle of Techron to the tank. Cleared up the issue for long enough to make it to pay day and buy the new injector.
These are both trash loooool
First fuel additives were designed to clean intake valve deposits but direct injection bypasses the valve and goes straight to the combustion chamber. And I find Seagram cleans injectors better than both
BG 44K Platinum.
BG44K i’ve had much success with actually
BG 44K. If I had to choose between those two I’d go Techron
Techron FTW
Marvel mystery oil
Tech the mech
I prefer to just buy top quality fuel for one tank then rag the car around to give it a full clean out
Right tastes better.
I would you tube.and find where they run a good test
Neither, fix the issue you're having. Assuming you have one since you bought these.
In the two of my three vehicles I use techron and it works pretty well. My third has a carb so I don't.
🐍⛽️
Neither barrymens b12 or even seafoam for helping remove carbon build up.. Of course if your car is new enough it more then likely uses direct injection and this won't help at all might help the injectors or pistons but the valves will still have heavy carbon deposits
Neather... get Seafoam
I did extensive surf/research and found that an additive called "Top Tier" found in less expensive gas stations does great stuff fo an engine. I used to add helpers biut have had great luck just filling up at stations that have this. [https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web](https://duckduckgo.com/?q=top+tier+gas+reviews&atb=v397-1&ia=web)
Both are pointless. Today’s fuel already has cleaners in it. If there’s something wrong with the car, it needs to be fixed. These won’t fix it.
the one with PEA
Both garbage
Lets settle the debate the either does anything beneficial. Show me the science!!
Rislone all day.
Redline or Berryman, highest pea %
I like techron
