just a cheerful note here-this may have been covered earlier in this long thread,but in my car if you actually calculate mpg (miles divided by gallons),it's about 1.5 mpg less than the reading in the dash display.i've checked this 4 or 5 times,always the same.are others having this experience?
last fillup,car said 14.3,it was really 12.8.
