From the manufacturer

Techron is a unique and powerful fuel additive

Pouring techron

What is Techron?

Techron is an additive technology that works to get the most out of your engine thanks to our patented fuel additive technology which is trusted by motorists, mechanics and auto manufacturers the world over. You can use Techron and when you do it will clean your engine, leading to better performance, lower emissions and maximum fuel economy.

What does it do?

Engines are designed to work at their best when they are clean and modern engines are designed to work with finer tolerances and at higher temperatures. Techron works molecule by molecule to prevent deposit formation, and in the case of deposits left behind by low quality gasoline, works to remove those deposits.

How does it work?

Techron is proven to be effective at keeping both modern and older engines clean. The result is maximum power, lower emissions and maximized fuel economy. There have been significant advances in engine design including hybrid and direct injection spark ignition technologies. These engines are designed to work at their best when they are clean. Even microscopic amounts of engine deposits can adversely affect performance.

Optimize your MPG

Every time you fill your tank, you expect to drive a certain amount of miles on it. An engine that's caked with deposits makes your engine work harder - less efficiently - every mile. So next time use Techron Concentrate Plus to help ensure maximum fuel economy.

Keep it Clean

Fact is, gasoline is a mixture of hydrocarbons including ethanol and other impurities. As it travels through your car's fuel system, harmful carbon deposits can form on critical engine parts. Techron helps remove these deposits, restoring lost power and performance.

    Saved me from buying a fuel pump: This stuff is the real deal
    I'll be honest, I was skeptical at first. I mean, who wouldn't be? I watched a few YT videos about fuel level problems and it turned out to most likely be due to fuel sediments in the fuel pump.So before jumping the gun and getting a new fuel pump, I decided to try this tip: pour a full bottle in a full gas tank...twice in a row. At first I was skeptical: Pouring some magic potion into your gas tank and expecting miracles? But boy, was I pleasantly surprised.We poured the first bottle...drove that car to empty...no luck yet.We poured the second bottle..and then the magic happened! all of a sudden the fuel gauge started working well again, and the car felt more responsive and fast!And the best part? It's not just a quick fix. Techron keeps on working, keeping my engine clean and happy for the long haul.Applying it couldn't be easier. Just pour it in with your regular fill-up, and let it do its thing. No mechanics, no fuss—just pour and go.So, if you're like me and you want to give your ride a little TLC without breaking the bank, give Chevron Techron a shot. It's the real deal—a down-to-earth solution for keeping your wheels turning and your engine purring.

    Compared to buying this in store with smaller bottles, you are saving a lot of money for the volume here. I highly recommend the bigger version. Just save what you don't use.

    As a product it feels like this one at least works and does some cleaning. I know it isn't going to save anything dire, but for small maintenance after Winter, I feel it does the job well in the fuel tank and other areas of concern.

    Size: 32 Fl Oz (Pack of 1)Style: 32 oz.Verified Purchase
    NOTE: If you are serious about buying this, see my caution below about putting it into your tank!

    I had a check engine light pop-up, and since I keep an OBD2 reader around, I went ahead and took a look. It came up as a low voltage in one the of 2 front O2 sensors. Given the number of miles on the truck, it wasn't a shocking thing at all - indeed, I had a full set of O2 sensors on hand for it already and just hadn't gotten around to it. After getting the apparently faulty unit swapped out, things were great - briefly - then the original error came back exactly as before. Intermittent problems = nasty to troubleshoot, so I did not have it resolved when a 2nd OBD2 error started being thrown - an issue with the fuel level sensor (a horror show to swap out if you have to do it). In investigating all the possibilities I got put onto running this stuff on at least 2 full tanks of gas. Since both issues were intermittent, it's hard to know if you *really* got the core issue resolved, but since things stuff first went in the tank, neither error has popped up again. Still too early to tell, but other owners of my model (an F-150 Ecoboost) frequently report noticeably improved fuel economy, so we'll see how that plays out.

    NOTE ABOUT PUTTING THIS IN THE TANK:
    I believe the sizes below the 32Oz I bought come with a nozzle built in that mimic's a fuel nozzle, so if you're ordering those sizes, you're probably fine, but keep in mind that this is a burnable, hazardous material. If it does not go in all the way (I would test it before breaking the seal), it will dump to the ground instead (a mechanical protection against people trying to sabotage your car by contaminating your fuel).
    For the 32Oz size or anything above that, you'll need to use a funnel or some purpose built attachment. There is a protective plate at the top of your gas receiver that is designed to only open when a specific size tube (matching an Unleaded fuel nozzle) is inserted. That plate will block your funnel from going in unless it is exactly that same size, which, since most funnels are tapered, it is unlikely size up correctly unless it is specifically built with fuel tanks in mind. You can find that kind of funnel here on Amazon. Alternatively, you can use an empty portable fuel tank if you have one, put the additive in that, and then use that to put it in the vehicle's tank. If neither of those is available, you can bypass the safety in the fuel receiver by triggering the related release points manually, but I will not provide detailed instructions for that here (spend a few extra bucks and buy the purpose built funnel!).

Limited choices to purchase as General Motors stopped making Cleens (repackaged Techron I believe) and Canadian Tire stopped carrying the 'Carburetor and Combustion Chamber Cleaner' (once again repackaged Techron I am sure) so it only left the actual Chevron product as the apparent and only actual product available to me here in Ontario Canada but a very pricey choice. Tried several other products with similar claims but all failed to work as well as the Techron product. Not the greatest value for the money but if you have fuel system gumming from a gasoline internal combustion engine sitting for a long period of time, there is no effective alternative that works as well.

    5.0 out of 5 stars Revived My Z06's Fuel Gauge

    I had been dealing with an annoyingly faulty fuel gauge in my C6 Z06 for months. It would get stuck reading empty no matter how much gas was actually in the tank. Extremely frustrating!

    After trying a few other fuel system cleaners with no luck, I decided to give Chevron's Techron Concentrate Plus a shot based on its good reputation. I'm really glad I did!

    I followed the instructions, adding one bottle of the cleaner concentrate to a near-empty gas tank and then filling up. After putting a couple tanks of gas through while using this stuff, the fuel gauge started working properly again.

    It seems the Techron was able to clean out whatever gunk or deposits were causing the fuel sender unit to misread and get stuck. The active detergent ingredients must have really knocked everything loose.

    Not only did it fix my gauge, but I could feel a noticeable improvement in engine responsiveness and power after using this quality cleaner. No more hesitation or rough idle.

    For any C6 owners struggling with fuel sending unit gremlins, I absolutely recommend picking up a pack of the Techron Concentrate Plus before taking more drastic measures. This cleaner has some serious resolving power when it comes to fuel system woes. Well worth the money for a working gauge again!

    After 30,000 kms odometer reading, this is the first time I added this fuel additive in my X3 30i and got a great result. Picked up the 20 oz (596 ml) bottle. And used it in 150 ml +150 ml + 300 ml in every alternate filling to my 65 ltrs petrol tank. Engine is very much smoother now, no more rough idling at start ups and experiencing instant power surge.
    Surely will use again after 5000 kms.
    What disappointing is the price is ever increasing, with-in a span of last two months, price gone up by 1000/- . That is shocking.

    Half bottle of 32 oz Techron conc plus fuel system cleaner was added to a full tank of 60 litres of gas and would help to restore the engineer performance by the time half tank of gas fuel was consumed. Great Stuff!!! I will use it again.
