I do not know the answer, but you do not need the actual tank capacity to
make this calculation. All you need to know is that it was full to start
and then again after refueling. If you know the amount of fuel consumed in
gallons and the distance traveled in miles then it is a simple math divide
operation to compute MPG (miles divided by gallons).
