Alcohol is harder on the materials used for seals on older and smaller engines. Plus if it sits the water absorbed will accelerate corrosion leading to pitting in say carburetors.
( this is for e10 not sure what would happen to a lawnmower with e85 lol)
Run whatever you want but if it were my money I wouldn't use e anything if I knew my car sat for more than a few days/ maybe a week at a time.

This idea that Ethanol is hard is really a misconception based on Methanol and its effects on Rubber.

Tests have been done quite a few times showing the lines even from a 91 MR2 can handle it with no ill effects after a year and then further. The only real issue that has been found running E85 has actually been sporadic and last I checked there wasn't a clear cut reason. Its a clear buildup at the tips of the injectors that varies. You can find it on the Turbo Buick, Evo Forums and LS1Tech but it will skip area's sometimes states and then appear else where so its thought to be a mix of additives in the gas possibly or how the Ethonal is made, aka what its made from.
