Current fresh gasoline w/stabill added will take on a peculiar odor and color in 6 months time and doesn't start well. So one has to figure out how to deal with this, so you don't have old gas sitting around like Charlie says. Michigan now has Ethanol in 87, today is the first I found it in no lead, the governor ordered that all gasoline be included, so our STC for auto fuel is no longer valid. That just raised the price of flying another buck a gallon. JohnD
There are some corn belt RV-x's that have been flying on pure ethanol for about a decade. If we make sure that the fuel system doesn't have anything that ethanol will attack & aren't flying high/cold enough to cause the ethanol to separate out, I don't see any compelling reason to quit using mogas in a homebuilt. We will just need to plan for the poorer fuel consumption numbers.
Corn's probably the worst source for the ethanol, but the ethanol itself shouldn't be a show stopper.
