It is not the ethanol in the gas that rusts tanks.Old plain-steel tanks will rust quickly from the 10% ethanol gasoline that we more or less have to use now. Ditto steel fuel pumps and lines. Worst are the early mid-80's to 90's fuel injected cars that were not made with ethanol in mind. Plastic or stainless is the way to go.
Moonshine, attracts water from the air, So it is the water that is in the moonshine, that rusts fuel components.
There is a couple of stations here that sells E-Free gas, at a quarter or so more cost per gallon. :vs_mad:
Another rip off, just like in the '70s when unleaded was new, it costs more to not add something? Balderdash.
