Well, just comparing the 550+ miles my wife has from the tank she bought in Oregon, plus the fact that there's still 1/4 tank in it and California gas only gets her 450 miles per tank, I'd say there's a big difference at least in legislated blends.


Well, our Oregon gas is now 10% ethonol year round too. It sounds like your wife just took a very long trip and I guess that and the highway only mileage and type of driving is what increased the mileage, rather than Oregon gas being superior, because I can assure you, it's not.
