Default Re: Fuel stabilizer

From what I've heard from a few good mechanics the harm to auto engines happens if the vehicle sits for a while and the fuel sepperates, since alcohol is higher octane than gasoline the higher octane fuel has more. Alcohol being water based will settle to the bottom of the tank and be burned off first, leaving very low octane fuel that can damage the engine. On small engines most carburator gaskets and seals were not designed for alcohol and swell or deteriate causing leaks or problems. I replaced the carburetor on my 70 GMC with a edelbrock in 2012, the instructions stated that using ethanol would void the warranty.
Your results may not be the same,Greg
