Believe what you want, but I get so much better gas mileage using NON-ethanol 85-87 octane gasoline than any of this 10% or 85% ethanol crap.

(Highway mileage)

2003 Toyolta Camry: 30mpg (E10) 33mpg (Non-ethanol)
2000 Focus: 31mpg (E10) 33mpt (Non-ethanol)
1983 Honda Motorcycle: 32mpg (E10) 36mpg (Non-ethanol)
1994 F250 : 9.5mpg (E10) 10.6 (Non-ethanol)

Luckily non of my vehicles can use E85. I'd probably go broke using that stuff. Plus it's not even any better for the environment. Most places aren't so fotunate. Our neighbors to the south is almost impossible to find gasoline without ethanol in it. Not sure how much longer Exxon can keep doing it, but I will keep supporting them. The price is the exact same as the E10 gasonline at other stations. But I get better mileage which means better for the ecology and environment. Later... Mike....
