Karl, NOT disagreeing with you on this, I'm right with you on it.|
Just an FYI: the fuel economy change is a bit more than you express.
Adding 10% alcohol should cause a 4.7% loss in fuel mileage assuming the same energy output of alcohol (which is a false assumption) based on a 14.7 to 1 A/F ratio for gasoline, and 8.1 A/F ratio for alcohol.
My informal testing shows an approximately 5.5% loss in fuel economy in my vehicle.
But since, in the lab, a 10% alcohol mixture reduces emissions, we must use it, never mind the pesky mileage issue, right?
