OK, my best estimate so far is that the new E10 gasoline is not doing much to my MPG around town, but is lowering my MPG materially on extended freeway runs.

Around town, we are getting 43-45 MPG, same as last year this time. Maybe a touch lower, at most 1 MPG change anyway. So, that suggests a 1% to 2% hit.

But I just drove from Portland to Olympia and back, averaged 53 MPG, I should have been more like 55-56 MPG. So that suggests a 4% hit.

Makes sense, in town the gasoline engine is running less of the time, while on the freeway it is running almost all the time.
