LK: Yes I don't think there is any "pure" gas available in PA, only "Up to 10% Ethanol" mixes. Oxygenation is another mileage ding ontop of ethanol however.
I just filled up tonight for the first time since Oct 3rd, I forgot to look for the oxygenation label cause I was in a hurry, but we'll see how the mileage is now.
That's a shame about the 28 MPG... something has to be going on. I actually cleared 29 on a tank once in the STi (with a lot of concentration). This last tank in the Fit was 39.5, and less than half was highway.
That means I could drive an extra trip from Philadelphia to Stamford, CT on every tank of gas at 39 vs. 28 MPG.
