E39 Fuel Tank Size

Can anyone tell me what the fuel tank capacity is of the E39?

I'm sure I have read that it is 70 litres and elsewhere (i.e. Haynes Manual I think) that it is 78 litres in capacity.

I was on the yellow light low fuel level warning on Friday night and on Saturday morning I managed to fill it with over 68 litres of V power.

The needle was the lowest I have seen it when driving with the low fuel level warning light on.  I was that concerned that I didn't go to the petrol station that I normally use and went to one nearer.  Just as well if I only had just over 1 litre left.

Thanks

70L seems about right but probably excludes the expansion space.  I brim mine (I know I probably shouldn't but the petrol generally doesn't stay in there too long!) and so probably squeeze in an extra 3 or 4 litres.  That would be reasonably consistent with the figures I calculate for consumption (or else the obc is massively underreading consumption - unlikely!).

The warning light on mine typically comes on at about 65 miles remaining which should equate to about 8 litres remaining in my case.
