my old X - 3.0i petrol: 23.9mpg best, 20.1mpg worst.
my 4.8iS, best so far 24.5mpg, worst 20.9mpg (unless you count the MPG when collected from the dealer - 7.9mpg!!!!! By the time I'd driven it home, it was up to 20.9!!!)

2003 3.0d manual transmission...

Worst 28mpg
Best 40.3mpg, over 240 mile round trip. Never repeated as I have no self control remaining!

My old 3.0i best: 27mpg over a 400 mile round trip mostly motorway (OBC rather than brimming the tank)

You do know that you shouldn't have said that don't you

Long trips this week - best 29.7mpg......I'm amazed by it! Approx 300 mile run got this, at some points it was over 30mpg but when I stopped at the end it was 29.7. I probably won't see that too often......

Best : 2004 4.8is = 27.1 & worst 2005 3.0d 19.1, though it was due a service

2004 X5 E53 3.od Sport Auto - I regularly get between 38mpg to 40mpg driving on the motorway to Scotland from Hampshire. This is both via the computer and a distance/mileage calculation myself

Hi,
2005 3.0d Auto.
Mine averages around 26 mpg although it has gone down slightly recently ( wife's lead foot ) this is mostly town driving.
Best so far was on 280 miles round trip of about 180 miles of motorway doing 70 - 80 mph & the rest single carriageway 30 - 60 limit.
Returned 32.0 on that trip
All according to the trip computor, never checked it properly yet.
On same subject but different car, I recently had a trip with my mate in his RR Sport 2.7d Auto.
When he picked me up it was showing average 16.9mpg
He re-set it & we did 120 miles of motorways at 75 - 80mph & it only went up to 23.7mpg.
I drove back, same trip but sat at 70ish & could only manage 25.6mpg, seems very poor to me, anyone had experience of RR Sport. Wouldn't have minded but it was quite a bit slower then my X5
