One thing I'd like to see is direct comparason between 0% and 10%. I'm wondering how much of our 'lost' mpgs is really due to the colder weather, as opposed to the added ethanol. since i can't get 0% regular now, i think this would have to be either done by someone in southern states, or i will have to wait until summer to do it.

-edit- i just saw where you live Giant, do you have 0% regular there?

This popped up into my mind because last week I finally had first hand experience as to how drastic the climate affects MPGs: it dropped to 15-20*f for a few days, and my average dropped to 38 from the previous week in the 40's getting ~43mpg! i cried, lol
