Fuel tank size (F11)
Discussion
I've only had my F11 for 5 weeks but I've filled it up five times already. The handbook says the tank is approximately 70 litres, which would be great; however, I have yet to get anything more than 64l into it. Last night the range was down to 14 miles and the permanent warning of miles to empty had been on since 30 miles remaining, but there should still be ~6l to use.
6l at 23mpg (worst case) would get me over 30 miles so the range reading seems very pessimistic. I'm not sure I'm willing to see how far after 0 miles it will run, though. Has anyone taken the gamble and managed to fit anything near 70l into their F10/F11? I'm guessing the fuel tanks are pretty much identical for petrol and diesel models.

My E61 is also a 70l tank. I too, am a fuel nazi and don't like filling up too early, hence I run it very low. When the range gets down to zero and I've filled up I've never got more than 66l in it, ergo I have ascertained that there is a ~1 gallon 'reserve'.
So, I won't have any qualms running it 15/20 miles from when the range hits zero.

The gauge under reads due to the fact that running the tank close to dry can damage the engine.
Please explain."If the fuel range drops below 50km, 30 miles, you should refuel as soon as possible, or engine function may be impaired and damage may occur."
I presume the fuel system, lines/pumps/injectors etc...are designed to work with fuel running through them?
I struggle to see why you think the fact that the fuel gauge / range is overly pessimistic by a few litres / 16 miles warrants a second thought, let alone a post on a forum. Seems a perfectly sensible margin of error on a 75litre tank / 4-600 mile range (depending on your car).

A gallon and a half of petrol is not fumes. Why would you not want to use the full range of your car?
Tell you what, why not just ignore the fuel warning light?That gives you full use of the 70L tank you BMW promised you, and the added excitement of not knowing exactly when you are going to creep to a sputtering halt!
Or, you could just fill up when the light tells you. That way, if you ever fall on hard times, you can go crazy on the couple of litres that BMW cleverly kept at arms length.

Excellent, you've just answered the question I was about to ask.So, I won't have any qualms running it 15/20 miles from when the range hits zero.
The most I've managed to get in is 63 with 20 miles showing remaining. I assumed the tank was about 66 litres.
