on top of the crappy gas...cold air is denserone thing I noticed is, if that instant mileage is remotely accurate, my truck hates a headwind. I was doing 65 into a strong headwind on a flat highway an was showing 15/16....at least a 6 mpg drop. Since the weather has warmed up an the winter blend of fuel is gone I've gained an easy 3 or 4 mpg compared to what I was getting over the winter.
