Chevron Techron Fuel System Cleaner (20 oz.)

I drive about a 1000 miles a week and always keep a bottle of this in my trunk. When you're driving all over the country, occasionally you must fill up your tank with a no-name brand of gasoline and if your car is fickle regarding the quality of the gasoline as mine is, then it won't be long before your engine's knock sensor is triggered and the CEL (Check Engine Light) activates. On more than one occasion, I've dumped a bottle of this into my gas tank and within 10-20 minutes, the engine returns to its expected performance and the Check Engine once again goes dark.

There is no question that this works as advertised. It is expensive, but if you live in a cooler climate, one that promotes condensation in your gas tank, or if your fuel injectors are simply dirty from a bad tank of fuel, then I cannot recommend this enough.

I am using this product for many years. the first time I was tried on my pinging Corolla. the car was ping so much, I switch from mid-grade gas to super and car still pings (The car pass smog check every time). After I tried just one bottle, All the ping went away back to use regular gas again. I highly recommand this product for anyone if your car is pinging.

I have a high mileage Durango. Since I bought it a few months ago secondhand, I have done some work on it. I tried the Shell and STP cleaners and I did notice some improvement, but I still had some valve noise. Also, the others were just and injector cleaner. After putting this cleaner in, I noticed an improvement in power, the valve noise has been reduced by a large amount, and even better mileage. Yes, you do pay more for this than the rest, but it cleanses the whole system, not just the injectors. Recommended

I saw a marked improvement in performance and sluggishness, for my vehicle, post applying this product. If you've never used it and have high mileage, 2 applications are required. Also, it's important to first pour this and THEN the fuel. Ensure your tank's at least 18 gallon, if you're using the 20 oz. or else go for the 12 oz. bottle. I would not recommend any additives but this and Tufoil. These are really good and most importantly, don't cause any harm to the engine.

This fuel system cleaner is definitely the best. I've used it for the 1st time in my Bimmer since it has been praised by many BMW fanatics. Keep in mind I have never used any fuel system cleaners in my car before. The power of the car is so much smoother and so is the pickup. The car just feels so much better. The lag is gone. This will be part of my regular maintenance for sure. I urge u to do research on Cheveron w/ techron technology. Very good info to be found....
