I think i understand the confusion. If i fill up reset the trip then use quarter of the tank(about 10 litres thats where it came from) then fill up To full not what i think i used then use the actual litres from the pump and the millage off the trip computer to work out the mpg![]()
I'm with you. That's fair enough, and like you day you can calculate the MPG. I think I miss understood you myself and assumed you were on about putting 10L in from when the red light comes on etc. So sorry if my last post sounded patronising, although I think a few others now realise what I'm on about with tank level vs guage level read out.
