On Saturday when I filled up the tank v e r y s l o w l y, the indicated mileage was ca. 46.5, yet when I divided the 433 miles by the 7.73 gallons, I had an mpg of 56!
On Monday, I again filled up with an indicated average 49.5 mpg. Again I put in 7.73 gallons but this time I'd only driven 276 miles so my actual mpg was 36.7.
There is an obvious problem with the way the MFD calculates the "average" mpg. Is there a way to calibrate it or should I take it in to be fixed?
