I used to road race motorcycles that had fuel checks on occasion. Most of the guys filled the low compression bikes with 110, I put 87-91 out of the pump in mine. Went to a race and the oxygenated fuel was in the pump and I almost got DQ'd for failing the fuel test. They pulled a sample from the rental car and it tested bad as well. No DQ. Once I realized that the fuel check would fail on pump gas, we put a nitromethane mix in the pump fuel. Bike ran pretty good then! :-D
I saved a bunch of money and it ran better than the race gas guys. Never told them my fuel source.
