Bad idea, too much ethanol will seriously harm older engines.
Boaters with older fiberglass fuel tanks know this all too well.
And its almost impossible to store a high ethanol fuel unless its in an air tight storage device, it naturally draws moisture, and adding chemicals like Stabil won’t work.
You buy a high ethanol fuel you must use it within a month unless you can keep moisture away from it.
Yep, and rots/rusts the gas tank.
Your spot on ethanol fuel is hell on the fuel system many new cars are going through fuel pumps at a high rate of speed the pro ethanol people say it’s only because people let their tanks get lower than 1/4 of a tank BS ethanol is crap.
