Weather permitting througout the month of February I quit using my Auto A/C. That combine with more moderate tempertures led to a pretty dramtic improvement in my fuel efficiency. My LMPG as of Feb. 1st was 44.2 My LMPG at the end of Feb. was 44.8 But, my Feb. MPG was 48.2 !! A full 4 MPG improvement over my previous lifetime numbers and 3 MPG better than my previous best month. And that was with some pretty dang cold driving days and a lot of short wasteful commutes. At this point I'm going to be really disappointed in any tank that comes in at less than 50MPG (my last 2 have been at or over that). I'm very pleased, as you can probably tell.
