Ethanol: Harmful ??

10% or less won't do much damage to your rubber fuel system parts. More than 10% will cause problems.

I took my lawn mower in for repairs last year and was told that the ethanol had ruined a gasket. He showed it ot me and was definitely in sad shape. Not a mechanic so don't know anything more than that - was someplace where it controlled the fuel flow I seem to remember.....

Well it must have been an old mower because the rubber used for small engines was re engineered to witstand ethanol almost ten years ago. What often happens is something else gets dumped in the fuel........cause it all burns right......
