^^^ and drive like a granny. 
GP20 says"300 miles in an Z4M is EASY. All you have to do is average 20.1 MPG"
On waht calculation is that unless u have fitted an ultra big tank. Mu tank capacity is 55lts. Even if I drive with miles miles left to fill up showing 0 miles and fill the tank i can only get close to 53-54lts. cant get the maths right here. its more like 225miles or so.

Fuel Tank capacity of 55 litres = 14.53 gal (US gal).
20.1MPG X 14.5gal = 292 miles. Close... probably looking at 20.7 MPG to achieve 300miles theoretically.
I get about 240-260 miles before I freak out on the needle and fill up.
I've been averaging <19MPG lately.

Mine's regularly giving me 300 miles on a tank and even then it'll only let me put a max of 50 litres in the tank. If I fill up as soon as the 'low fuel' light comes on I can't get over 40 litres in and the OBC shows that light at 60 miles to empty.
I work that out at about 26mpg average - although that's probably 240 miles of motorway at 80-90mph and 60 miles of A/B roads at 30-60mph.
If I cruise at 70mph for a good few miles I can get it over 30mpg, and if I put it into 6th and use light throttle at 35mph I can get over 40mpg although I can usually only do that 6th gear low throttle in 40mph roadwork sections on dual carriageways as that shoots down very quickly once a set of traffic lights come into play.

The only problem with getting 40mpg is you just can't move your foot on the pedal once it's at the correct speed & revs, otherwise it either slows the car or you see the MPG figure dropping quickly - you can get higher figures, but you need to be going downhill 
just for the record i've had my new one for 15000 miles (the old one it did 10000) and this one definately seems more economical... the more miles i do the better it seems to get... (sorry i'm obsessed with MPG thats what having a co car and fuel card for 10 years does to you lol)
on the way back from the petrol station tonight (its 2.5 miles straight flatish Aroad) at approx50-60 mph i got the clock to 39.4! just didn't hit the 40mpg 8)
