I wish I had the OBC mpg readout. I'm basing my mpg on amount of fuel at each fill-up and the miles traveled since the last fill-up. This number has been pretty consistent over the last, say, 10 fill-ups or so.
I had the OBC mpg readout on a 93 BMW 325is and it was usually fairly accurate compared to the real world, do-it-yourself calculation at the pump at each fill-up - but it was important to reset the computer mpg calculator at each fill-up to make a valid comparision.
