My usual filling station (in the UK) has just installed new pumps that state on them "Volume corrected to 15 Celsius, this does not apply to biodiesel" (Gilbarco Veeder-Root made pump, replaced a Wayne Dressler made pump)
I wonder if this means the old tip of filling up at night/in the cold to get more fuel is now no longer possible?
I usually fill at night and I don't think I have noticed a change.

*if* there was significant temperature fluctuation (which there isn't), then the old advice would still be true, in so much as the fuel would still change volume slightly on a temperature change. However as Ciderbarrel notes, because the tanks are underground, the temperature does not significantly fluctuate.
At the moment I have a slightly different take on filling up at night.
My car has a very small fuel tank (30 litres nominal--can get 31.5 when brimming it) as a result of a wheelchair conversion (the full size tank was removed to allow the rear floor to be dropped and form a rear entry ramp). Not that I need a wheelchair, it was just a cheap low mileage car when I needed one.
So getting a little more fuel in the tank (because the CAR's tank is cold) increases my range just a little.
(In case you are asking: Nissan Prairie Pro M11 with Brotherwood w/c conversion).
