3 and a half even.
Compared to my 5 fill ups a week over the summer, this is a major improvement. Not really concerned that my actual MPG is dropping (The 3 weeks was 23 mpg with no scangauge) since I'm still using 12 gallons a month compared to 120+.
I'm going to shoot for a solid month next, but it's going to be hard considering winter is almost here and I'm going to have a hard time convincing myself to walk/bike when it's cold and wet.
