What is STP and how does it work?
Sep 25, 2014 · the STP red bottle is no better than the Gumout Gas treatment (also red bottle). It's a lightweight kerosene and can't even clean a lawnmower carb. Why people buy it is only because of the price and advertising. STP I think last year was advertising "Jet Fuel" on their labling.. didn't mean it was good then, and it's still pretty bad now IMHO.

The only problem I see here is the engine may get used to this boost, and am wondering the long term action on the injectors. I used HD Duralt for years in my Evos, I am leary of any thing added to my gas any more tho there is too much junk in the gas now catch 22 IMO

Most injector cleaner's have alcohol in them and it is hard on the O rings in the injectors I was told.

Across the country Ethonal is becoming common place up to 10% and hear say has it Uncle Sam wants to make it up to 15%. May be a little octane booster in the right measured dose per tank might become the norm for these high octane Iron Horses we all have such a passion for.

Using Gas Treatment in too high concentration may stress seals in the injection system, but in at proper level should not hurt. But it is not gasoline, so actual performance may suffer as it by quantity displaces the designed proper gas fuel mixture.
