Putting a "fiver" in is nowhere near any good enough to get a good fuel reading, the gauge is useless
The best way to actually work your mpg is brim the tank then drive then brim it again
Amen to that to, Gauge is hugely inaccurate! I think it works well when you have over half a tank in, but under that you might aswell drop rocks down the filler and listen for the splash!
Edit: Also some say it differs between what diesel you use.... So try 10quid of shell and then 10quid of asda and see if you notice any difference?
Doesnt even own a 306.
