E85 burns faster than gas, so you'd get even worse MPG than you currently do even if your engine was able to run E85...and you had it available in your area.
Adding up to 10% ethanol in engines is a way to increase the octane ratings in fuel and still have it run in all engines.
^^ what he said. Running 10% ethanol itself is giving me slightly lower mpg's (houston just changed this past month).
It shouldnt be that apparent in E10 blends.
E85 drops it MPGs about 10-25%, so E10 would drop it no more than 2-3%, which isnt even 1mpg. (Ethanol blends also are higher octane - E85 is somewhere from 100 to 110, so theyll also make more power in engines equipped with the Ethanol-fuel sensor that current "flexfuel" cars have.)
Ethanol also reduces emissions, which is one of the reasons E10 is getting spread. E10 is mandated in a few states already.
You may not have a problem using E85 in the short term, but it will corrode your injectors and other parts of your fuel system if it isnt built for it. And obviously, they won't warrantee this.
