Are you calculating the MPG based on miles driven/gas filled up, or is this the number you're reading off the OBC?
I'm reading the miles driven since last fillup off the on-board computer, and the gallons on fillup. The on-board mpg indicator which measures avg mpg since the last fillup agrees with the total miles driven/gallons pumped. I set the miles back to zero after each fillup.
