Oxygenated gas has alchohol in it and higher octane than gas alone. I don't know why, but it gets worse mileage. I remember the word was you needed to double the fuel delivery to run alchohol classes at the track. I guess it is just the more you mix in, the lower the mileage will be.

Well I guess the winter blends are gone. I took a 250 mile trip and got 15.3 (hand calculated). 15.6 on the overhead console. I think thats pretty good for a V10. The last trip I took on winter fuel it was 11.5.
