>>a certain amount of fuel has been added. About 3 gallons I guess.
This issue was at the heart of my original post. I read the manual for the car and it talked about resetting after fuel was added, but that is not how mine was working. On my first 2 fillups, I added 8 and 9 gallons. About 30 seconds after starting back up, the # Miles on the MFD reset, but the MPG calculation did not. It stayed right where it was prior. That's why I asked the question whether people were resetting the MFD on their own or were using it as a "lifetime" MPG calculation.
Has anyone else experienced this discrepancy in what the manual describes versus what actually happens at fillup?
