Chevron Techron Concentrate Plus Fuel System Cleaner, 12 oz, Pack of 1

Chevron Techron Concentrate Plus Fuel System Cleaner is one of the best fuel additives I have used for maintaining engine performance and keeping the fuel system clean. After using it consistently, I noticed smoother acceleration, improved throttle response, and a more stable idle, especially on higher mileage vehicles. The product is very easy to use — simply pour the bottle into the fuel tank before filling up. It works effectively to clean fuel injectors, intake valves, and combustion chamber deposits without requiring any special tools or complicated process. Many fuel system cleaners make big claims, but Techron is one of the few that actually delivers noticeable results. One thing that stands out is how well it helps restore performance over time. Vehicles that felt slightly sluggish or rough during acceleration seemed to run smoother after a full tank treated with Techron. It can also help improve fuel economy when used regularly as part of normal maintenance. Chevron’s reputation in fuel technology gives added confidence, and this cleaner is commonly recommended by mechanics and automotive enthusiasts alike. It is safe for a wide range of gasoline engines and works well in both newer and older vehicles. Overall, Chevron Techron Concentrate Plus Fuel System Cleaner is an excellent preventative maintenance product that provides real benefits without costing much. It is reliable, easy to use, and highly effective at helping engines run cleaner and smoother. Highly recommended for anyone looking to maintain long-term engine performance.

When you sense that your car is running just a bit sluggish or your gas mileage is getting worse, not better, this should be your first choice to remedy your problem. Techron ios excellent because it does several jobs in one application. First of all it immediately cleans your injectors which get fouled up from bad gas. Cleaning them as well as cleaning your rods and lifter lets your engine breath and not work as hard which makes it run SMOOTHER and that will definitely improve both performance while it increases your mileage tremendously right away. Wait until you are down to a quarter tank or less and add a whole bottle right into your gas gas tank, and then fill up. That's all there is to it. It starts doing its thing right away and you'll feel the improvement in performance almost immediately. I have a C-5 Corvette as my daily driver and I add a bottle to my gas tank about every two months and it really makes a huge difference. Try it and I'll bet you'll be pleasantly surprised on your first tank.

This Techron additive is the best PEA (Poly Ether Amine) product out there in terms of the amount of PEA per oz you are getting. As a result, it works well in my experience on two different problems, within limits. a. It is VERY good at reducing or eliminating engine knock. However, you have to use it a while (longer than the marketing blurb of one bottle). In my experience, to rid yourself of engine knock, use TWO bottles on one tank of gas on a car, e.g. 20 gallon tank. (4 bottles on one tank of gas on a truck, e.g. 30 gallon tank) That is for the first use. Then after going through that tank in natural driving, then use 1 more bottle per tank for two more tanks. (On a truck, that 6 bottles). On a car, that is 4 bottles. More than they say you need, but that is my experience. b. It is OK at remedying Catalytic converter problems. (e.g. P0420 code signifies "Catalyst System Efficiency Below Threshold (Bank 1), or the similar P0421 (for Bank2). These codes fire when your catalytic converter is not working. Whether Techron can help fix that or not depends on your vehicle's situation, and how long its been having an issue. The short version, if its been a long time (months and months, or years), this product is unlikely to solve your problems. That is because not only did the vehicle throw the catalytic convert code, but you ignored it a long time. Which typically means that you Catalytic converter has been getting over-temped for a long time, and you have likely melted a good chunk of the internal honeycomb structure as a result. No magic gas tank chemical is going to fix that. But if your vehicle "just' threw the code, this stuff might work. A LOT of the time on older cars, the issue(s) are that you have older rings on your cylinders and they are leaking more oil to the PCV system, and then back into the air intake. That is really dirty oily air, being "reburned" at the demand of Air Quality standards people, to keep the atomosphere cleaner. But its putting tons of oily dirty air through your cylinders and then catalytic converter. That oil doesn't all burn in the cylinder, and so it flows to the Catalytic converter, where it does 1 of two things. It either burns, and coats your platinum coated honeycomb with carbon deposits, or it is not all burned, and it coats it with carbon deposits and "wet oil" residue. This Techron seems to be very good at cleaning up both of those issues. I have old cars, and both (now) use oil catch cans, installed between the PCV valve on the engine, and the air intake's auxillary "SMOG" recycle input orifice. (There is a rubber or metal tube line that runs from the PCV valve to the air intake. An oil catch can is a great idea to catch and cleanup a lot of this oil in that air before it makes it to your engine. This Techron is the other end of the problem. In the gas, it helps clean up the carbon and oil residue in the Catalytic converter (and on your cylinder heads and piston tops), getting rid of knocks (the later), and Cat codes (the former). But as I said. If your Catalytic converter is too far gone, nothing will help it. But spending $100 on 4-6 bottles of this Techron is often worth the effort to "heal" your Cat enough to pass a test. Long term, an oil catch can, and different driving patterns, and checking your spark plugs and ignition coils is worth while. Mis-gaped spark plugs (they wear over time) and aging and imperfect coils can also cause the same problems. Unburned gasoline (instead of oil) that clogs up the Cat. I have fixed my Cat twice now with this stuff. (Each brought on by long drives, over mountain pass freeways (4500 ft., and 4000 ft. (from sea level) charging up the mountain at sustained engine loading. That tends to make old engines just "crap" oil into the air intake (via rings, PVC, intake-second burn) and clog up your Cat. Put some of this stuff in right away, and it can often be reverse without the Cat having gotten SO hot, that it melted the honeycomb, or SO clogged (if not melted), that no chemical is going to succeed to getting the blockage cleaned out. All PEA is good, and this has the most.

Very good product for your car, works, Very well. Would recommend this product 100%.hope you like the product like I did.

The product is recommended for Jeeps; I’ve used it for years and I know it works.

The Chevron stuff is fantastic and is a great price. I prefer Redline SI-1, but those are very expensive right now and Chevron stuff is a close second. Now Amazon could do a better shipping job here. The package clearly shows arrows so the box doesn't get placed on its side. They leak. I lost a few ounces, so be aware. Again great product and I'll most likely buy it again.

Using this product with PEA and Top Tier gas has my Chevy Silverado getting 17 to 20 miles per gallon city and freeway driving. I am using the DOD delete to keep the engine running all 8 cylinders. And I’m seeing little change in gas mileage from when the engine would drop 4 cylinders.

This is the second time I am ordering Techron Fuel system cleaner. Unfortunately, they are not available in Canada and my wife should bring it for me from the US, every time she comes to Toronto. Such a wonderful product that you feel the difference before and after adding it to your fuel. I definitely keep buying and using it. Take care of your car, and it will take care of you.

Does what it advertises if you follow instructions ;o)

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.

Refresh engine

Good one

You will notice a pickup in the power of the engine after using. Vehicle accelerates more responsively. Be sure to drive it on a longer journey as the carbon is burnt off when engine is at normal operating temperature, not on short trips. Also be more aggressive on accelerating RPM to allow the product to burn off the carbon build up (once car up to temperature). Its the PEA content that cleans the carbon buildup. Advice is to schedule to use this at least 2 full fuel tank fill ups before an expected oil change, so by time you change your oil this product is completely used and no longer in fuel system. Example - I use every 8,000km and change oil at 10,000km. (Each fuel tank gets approx 1,000km). Use before every engine oil change to maintain a clean fuel system. Importantly - use this with high octane fuel(95 Octane), not cheap fuel (87/89 Octane). It needs the higher Octane to work best. Result will be better fuel mileage and restored power.
