Basically i think the data is meaningless for all the reasons given
The way I use to do it you could try this…
1. Fill the tank up to the click.
2. Zero the tip meter.
3. Drive as you normally would until your next fill up.
4. Now fill the tank up to the click again.
5. When you pay get a receipt and note the mileage you have done
6. Then do the following calculation.
7. Number of Gallons of Fuel = No of litres of fuel ÷ 4.5461
8. MPG = Miles Recorded ÷ Number of Gallons of Fuel
e.g.
No of litres = 35
Miles covered = 250
35 ÷ 4.5461 = 7.699
250 ÷ 7.699 = 32.472 mpg
Do this a few times keeping a note of your mpg then you can assess the average.
