Review: Great fuel system cleaner - I used this fuel system cleaner with my fuel, and it worked better than expected. After running it through, it actually cleared the catalytic converter code that had been showing up on my vehicle. The product was easy to use — just add it to the fuel tank — and I noticed smoother performance afterward. The quality is excellent, and it feels like a reliable solution for keeping the fuel system clean and running efficiently. On top of that, it saved me from a costly repair by resolving the code issue. Overall, this is a great fuel system cleaner that delivers real results. I’ll definitely keep using it as part of my regular maintenance routine.
Review: Mixed Success, but still the best product out there - 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.

### ⭐⭐⭐⭐⭐ Great product, helps to keep the motor runnin' smooth and peppy.
*by D***E on January 10, 2026*

I like this product, I do a lot of short distant driving in a new car. So to keep the carbon deposits down and keep the injectors clean, I use this every 6000 mi or so. As a rule, I don't like adding any fuel or oil additives, with the exception of this. It's a concentrated form of what many gas brands use in their gas.
