Right now my tank is sitting at 39.9 on the MFD, which last month would have been around 43. (calculated MPG is less - around 41). I'm hoping to nudge the MFD up over 40 before I fill up (only about 400 miles so far on this tank) as it might be my last 40+ tank until spring :-(

Having said that my old trailblazer used to get about 16 in the winter so I'm still way up :-)
