I put 5 gallons of e85 in my tank of 10 gallons half of which was e10 and I want to say mpg went up as well as performance.

I saw upwards to a 10mpg increase,but that was a difficult test to repeat with all this cold wet, frozen weather on the east coast.

I think its due to more of the octane rating vs ethanol.
