Any information out there about acetone or 2 cycle oil as additives to increase gas mileage?
No, just increasing tire air pressure to 36 psi (cold) and using full synthetic engine oil like Mobil One.
I've look at many of these, and have yet to find one that actually works. Most actually increase your fuel consumption, no matter what they claim. A few will actually damage your engine. Always use what the engine was designed to use. Good luck!
All additives are worthless (for mileage) none of them work.
