Can I use gas that's been sitting in a tank for bout a year if I put a 12 oz. bottle of ISO heat in with it?
No get rid of it I would not try it
Agree,that gas is mostly water by now.
Okay thank you both (: I recently bought a 91 stealth and it was sittin for a year. It had a full tank of gas in it. But at the price of gas I wish I could use it for somethin but I definitely ain't gonna ruin the engine over a tank of gas.
