Fuel Economy
Love to get my hands on one of these and see what it really would do with E85, E85 numbers are currently all calculated at 1/3 loss.
Interesting E50 is 96-97 octane, some E85 proponents would like E50 to be the standard due to the lower reduction in mileage than E85. I'd prefer every pump be a blender so I could choose the blend I like based on my cents/mile. E50 would be under $2 a gallon today.
No idea what it would take for the refiners to make 96 octane without ethanol, race gas down the street is $7 a gallon I think it's 104 octane. So a guess would be it would take a 50/50 blend of 104 and 85 to make 95, around $5 a gallon.
