i guess one thing i still find strange is that my mpg still has not strayed from 45.7. before i took my trip i was getting close to 48 mpg doing my regular everyday things. when i commute to work on the 280 towards palo alto i drive about 70mph for 20 minutes. if i wind up in stop and go it changes a little but not much. so i guess i'm just surprised that my mpg hasn't gone back up yet after the long trip. basically i'm getting the same mileage doing everyday commute things as i got doing a 6 hour 70 miles per hour trip, which is 45.7. whereas before i was steadily getting better and better mpg until i got to 48.
