What type of diesel fuel?

[Paul_13]

No its the other way I think, rather than being generous the 'next' pump gives you less by clicking off early due to foaming or whatever, which makes it appear that you've used less fuel than you actually have... Same can happen when the tanks really empty I find.

That's why I stand there and brim it for bloody ages until it's literally at the fuel cap level, waiting for it to go down and level out each time
