The OBC uses a flow meter to calculate MPG and if anything it is consistent--manually dividing the gallons at the pump into the miles traveled is not very accurate--every pump nozzle shuts off at different times and you never get a fillup unless you overflow the tank--and that will trip a fault in the computer. Also the gas from the underground tank may be cold--pump it into your tank and it will warm up and expand--
BTW this is the 21st century--computers replaced pencil and paper  |
hhmm lets see if i understand
our hand held GPS says we've traveled 100 miles and the OBC says 105 = OBC correct
our hand held calculator says 20 MPG calculated by using OBC provided miles divided by gals provided by pump, OBC says 21.5 MPG = OBC correct
these calculations have been made for every (almost) tank of gas for 40000 miles = OBC correct
