Re: Regular with up to 10% booze-a-haul, or high octane w/out?
The "stabilizers" in oil are there primarily to make it sound good on the container. They have nothing to do with storing the gas or protecting your engine. The stabilizers that are sold separately are of a much better quality, and not very expensive. few dollars for a pint or a quart, forget which, that you only need a capful or two to mix with a whole gallon of gas. I dont use fuel stabilizers myself.
