E-10 and E-15 fuels use alcohol as an oxygenator, so if you buy a stabilizer with alcohol you're just adding more of what your fuel already has. Read the labels before you buy. Sta-Bil does not contain alcohol.

Two different types of alcohols, in the fuel is ethanol made usually from corn & evaporates to a sugary type gunk, the alcohol in in stabilizers is methanol a petroleum product used the absorb/disperse moisture.
