Chevron Techron Concentrate Plus Fuel System Cleaner

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.

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.

I’ve used fuel system cleaners before, and this one is one I keep coming back to. Just pour it into the tank and drive, couldn’t be easier. After running it through, I noticed smoother performance, especially at idle and during acceleration. Nothing dramatic overnight, but definitely a noticeable improvement. It’s a good option for helping keep the fuel system clean and running the way it should, especially if the vehicle does a lot of short trips. I also like using it as part of regular maintenance every so often rather than waiting for problems to show up. For the price and ease of use, it’s a simple way to help maintain engine performance. Bottom line, easy to use and a solid choice for routine maintenance.

Good product that always rates well in testing. Unfortunately, the price has tripled over the past 5 years.

This is one of the very few fuel additives that's pretty much proven to work to reduce carbon and other deposits on your vales and upper cyclinder of your engine. Chevron/Texaco Inc makes a solid consistent product that just works!

My ‘07 Ford F-150 was suffering from age and the poor gas I was buying at a local convenience store. I ran two bottles through (two tanks) and I noticed a nice improvement in how it ran. Sputtering cleared up. Worked for me and was a nice surprise as I was expecting to spend some big money.

Excellent product.If you google it, it's always number one product to put into your gas tanks , it always comes up, Number one, i've been buying it for years.My car's running great.I trust it, I use it.I suggest it to all my family and friends.I highly recommend it. Thank you so much, Adam Altman

We have 3 cars and I use this juice in each one. All vehicles have less than 55k. One is our daily driver which we will dump more juice in it because we use more CA polluted gas in it. I can surely tell the difference. Vehicles run smoothly from idle thru WOT. Gas mileage a tad better and more consistent.

Excellent

منتج جبار جدا مقارنه بسعره كنت استخدم منتجات لوكاس و لوكي مولي ولكن لم تعطيني نفس النتيجه كان عندي نفضه بالسياره بسبب انسداد بخاخات البنزين و مع ثاني علبه اختفت تماما

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
