I just recently added two bottles of STP Gas Treatment (they only had the small bottles), and another of Fuel Injector cleaner.

Oddly, I'm getting some sputtering when I first start the rig up in the morning.

I don't know if the sputtering has anything to do with the additives (spark plugs are brand new, and engine just got new fuel filter, air filter, etc.), but it got me wondering if that stuff is worth adding to the fuel tank at all.

Thanks!

P.S. - Is their ANY validity to the idea of running a tank of Premium every now and then just to clean out the engine? I've heard equally convincing arguments that the idea is bunk.


Injector cleaner is ok every 6-months, other than that your wasting money on it if it's a regularly driven ride. For us out here it's a benefit to use it because of the high humidity and salt air. Things Rust like crazy out here... Even a tank that's half empty.

Gas treatment well, I never used the stuff before so I wouldn't know *sorry.

As for your sputtering woas, sounds like you got to much of that stuff in there or it's actually working and you motor is eating up the junk that its cleaning out...

Premium gas is good if you can afford it, otherwise your motor should run fine on the lesser grade stuff. Have your timing checked if your not running as well on low octane fuel.
