Default Mileage Change
I just found this site and am pretty excited. . . Hoping I can get all my questions answered. . . Is there any logical reason I could have a drastic drop in mileage. The first 2500 miles I was averaging 13.5. Now I can't get over 12. . .?

Make sure you live in a place where you can get away with the deletes. If you can, do it.
