The Rotax engine is approved for up to 10% ethanol. The various Phoenix fuel components and fuel tank are also protected from up to 10% ethanol. However, ehtanol has such a corrosive nature to plastic, rubber, and composite materials that it is best to stay away from it.
Here in Melbourne, we have 3 gas stations that carry 90 and 93 octane E0 fuel. Four 5gallon jugs typically last 2 weeks around here, so it is not a big deal to ferry fuel to the hangar. The 100hp 912ULS engine requires 91octane minimum so we use premium. E0 gas stations are usually located near marinas, airports, and racetracks.
