Well I knocked off 64.7Mpg around town today on a 4 mile drive in town, during lunch hour(heavy traffic)
I can't wait til I get MpGuino showing real MPG numbers they are low right now, I am guessing 64.7 was actually over 70 based on old tanks.
Edit:I hit 69.8Mpg on the return trip 3.5 miles one less place to stop.
