My first tank was 33mpg. When I filled yesterday (159 miles / 5.1 gal), I was down to 31.17mpg (and I didn't even get it quite as full as I started with). Hopefully this is the bottom though. It was -15f yesterday morning going to work and only +4 on the way home. I have the windshield all the way up and was running between 75 and 83mph indicated on the freeway for most of these miles. Add to that the winter fuel blend (if there really is such a thing) and I've ended up with some pretty poor mileage. I know that others in the group have hit these numbers as well, but that's usually from playing hard. I'm actually taking it pretty easy and using the cruise once I get up to speed. I'll save any fun for this summer when the traction improves.
