The onboard computer is not the most accurate way of working out the actual consumption figure.

 

What it does do is work out the complete average from when it was last reset till now. It incorporates all driving and sitting in traffic with the engine running.

 

The best way is to fill the tank to maximum, reset the trip meter, run the car for say 100 miles and then refill the tank again. You can then use the figure for how much fuel you put in and work out the exact mpg.

that is the way I do the calculation in my other car and it works ok. So, what you're saying is reset each time and calculate that way. Will that stop the fuel gauge needle going down as quick as it does now! When I first acquired the car the mpg part of the instrument went up and down the scale as it should even with the fan fault that's now cured.
