Ethanol free gas

Yup...I should have mentioned that too....either know your source of special fuel, or stick with a high volume, tier-one producer of gasoline.

Dont' forget we are also stuck with only 91 octane on the Premium gas (not 93 like other states).

Not sure if the information still hold true today, but I do remember ASTM lowering the E85's min ethanol requirement to 51% back in 2011 or 2012.

My Evo runs E85 (flex fuel) and my gauge pretty much shows it at a consistent 80% all the time. While it's supposed to fluctuate between summer and winter blends, I don't recall the last time it dipped below 80% (except when I top up with non-E85 of course, so yes, the gauge is accurate )

Thanks!
