Turns out our area doesn't have summer/winter fuel, maybe my tires are just wearing in or the air being warmer.
Anyhow I've just resolved another small issue that was affecting my gas mileage. I had a small leak around the intake manifold gasket and it was causing a very soft idle surge on cool mornings when rolling. I just averaged 45mpg on my way back from school without using EoC, where my previous best was 38.
