What is your experiance?
Stock 87 CRX 38+ w/reg---33 w/E10, more than 10% loss.
In testing E10 I find 3.5%-15% ethanol, about impossible to do ANYTHING with fuel adds or tuning on a regular basis.
The only save is a few 100% gas stations here, that will change I'm sure.
I am in Boise, Id. They just brought on a E plant, all my cars do worse on E.
And its no cheaper. And I use more gas+E. SNAFU
How is this 'GREEN'?
