Anyone feel that the fuel tank is 10L or 15L off what it should be, when you get around 220 miles per tank it gets boring at the pump.

I'll normally stop to fill-up at about 350 miles, but always have an indicated buffer of over 150 left in the tank.

This car can achieve exceptional mileage if left in either of the first two automatic shift positions. Manual shifting will dramatically reduce mileage.

Probably because I'm an old man, I don't need to be pushing the limits like some of you younger owners.

Also, I drive on mostly rural roads, so my mileage shouldn't be considered typical.

Does that mean you can get 500 miles a tank?

Yep. It's the same size as the E60 M5, which people complained about. They increased the fuel tank size in the F10 M5, which made people happy and now decreased it back again in the F90

Any ideas why? Weight ?

Yes.

The capacity indicated in my owners manual is US gal/liters 20.0/76.0.

500 miles per tank ? wow i never get more than 270

[DannyA]

Unreal! You sure your not in a 520d

No way..my car shows that number when fuel tank is full.😂
I would like to see you average consuption.

I’ve cleared 800 km (500 miles) 3 times in a single tank; all open highway at essentially legal speeds. It should be noted that all 3 tanks were before the car had 3,000 miles on it. I’m now at 8000 miles and getting more like 700 km per tank. I guess I’m driving it harder as I go along.

The biggest barriers to good mileage are - shifting manually, traffic, high "sustained" speeds, short trips (especially in cold weather) that don't let the car warm-up. My normal drives avoid all these pitfalls.

My rear tires are ready for replacement, so I'm not babying this thing.

Considering that I am in the break-in period, still on my first tank! Mostly on backroads with varying speeds and revs where i switch between economy and sport plus with shift settings D1 or D2.

I will get around 570 km while really having fun, I am impressed! I am at or below 11L - the car is not even broken in and I was maybe only 25% on the highway. I can only imagine what this car could do when broken in and having a trip on a highway at legal speeds.

As requested - Average speed and fuel consumption. The Onboard Computer has never been reset since I got the car 10,000 miles ago. This was just after I filled up and shows projected mileage at 551.

I know my circumstances won't apply to everybody, but at least this shows that a big V8 with a proper automatic can still provide surprisingly good mileage.

yes i can imagine that when you mostly drive on the highway with cruise control and an average speed of 43 mph,wow impressive 25.6 mpg tbh.
this fuel consumption is a dream when its all city driving and an average speed of 25 . i reset mine a week ago and drove really careful and got at best 16.5
i once on a road trip got a range of 625 km (388 mile ) doing the swedish speed limit 110 km h (70 mph) on the highway but never checked fuel consumption

I wouldn't read too much into the 43 mph. This is over a period of 10,000 miles and 15 months. My typical drive on rural roads is moderate (60 mph), with some over-indulgence thrown in where appropriate.

I don't want this to be a recurring theme -

Wow..congrats man! I wonder on the other hand how big consumtion is in X5 M50i or in X5M in city...11 mpg or less?!
