Has anyone used STP gas treatment on their car?

I didn’t notice much of a difference in gas for my car, but I know some people who use it religiously. I have never heard of it harming someone’s car though.

it saves gas and it will not harm your car i perfer to use berrymans its in a big metal can and it works better that anything ive ever used

You will never see the difference in gas savings,but it does clean you injectors. You can use anything with Petroleum distillates in it. That is what cleans your carb jets or injectors.Use it once a month on a full tank.that will help ensure the best burning of the gas.

You probably wont notice much in the way of fuel mileage, and it wont hurt unless you use way too much for the amount of fuel, it does do a nice ob of keeping the fuel delivery system clean.

dont use gas treatment in your car, if its fuel injected. i dont like stp, i perfer gumout or outlaw fuel injection cleaner.

I have used it in my 98 Honda Accord and never had a problem. Though I couldn’t really tell you if it improved mileage or not
