We've got 20 or so gasoline burning pieces of equipment at work. We used to buy all our gas right from the airport. The alcohol content has been so high that anything aluminum in the system is eaten up. Or, the old style o rings and rubber lines are eaten up and we have had to replace many components due to the ethanol and alcohol. We have been buying our gas from quick fuel for the last year and that was the only way we could get a no ethanol gas and be certain. When we met with the quick fuel reps, I couldn't believe the stuff they told us all the gas stations were doing. It's just as bad, actually worse on the biodiesel.
