I do a moderate amount of fixings on older snowmachines in Alaska and I see occasionally cases where the pick up hose in the fuel tank splits because of certain fuels coming from Anchorage years ago, they tried adding something to the fuel years ago to create less clouding in arctic temps, well it immediately screwed up several thousand cars and the oxygen sensors.
I bought an older Honda CX 500 some years ago, had some ethanol type of gas in it and was in storage, ate all the rubber diaphragms apart. Fortunately where I am in Wasilla we do NOT have to be forced to buy ethanol added fuel here, no two hose pumps with vapor bellows or febrile pumps that just trickle the gas in to reduce vapors escaping while fueling.
Ethanol is good for race cars and engines designed to run off it, you cannot even use that gas in older boats with fiberglass fuel tanks, eats the resin up.
I know 2 homebuilt aircraft pilots running auto gas who's fiberglass tanks did just that. One landed on a highway, the other limped along, called a percautionary landing and this was during the test flight phase. He has since had to do a major redue to remove the tank and put an all aluminum one in.
