Highway Commuters - x5 35d real world gas mileage?

This just proves my point: people report amazing MPGs based on short, exceptional experiences. Drive for few thousand miles, and you'll get more realistic mileage.

24.5 over the first 2,300 miles per the computer

I'll check this recent tank today to verify that the computer is close, but I expect it will be, it was a 24.5 average before this tank fill and I've got ~450 miles on the tank with a range of ~100 left. If I read the Owners manual correctly its a 26 gallon tank with a 3 gallon reserve correct? Which means the computer would use about 23 gallons to compute the miles to empty?

I think when you look at higher cost of diesel you have to also look at, your maintenance long run should be much less then a gas car,and if BMW makes a engine like MB you should get 400K out of it.

The tank is 22.5 gallons.

How exactly more frequent oil changes, DEF refills would make it cheaper than a gas car? And let's not forget potential visit from a turbo lady...

472 miles on 19.1 gallons - 24.7 mpg

Mostly my commute for the last 2 weeks which is 10 miles of 70 mph interstate, 4 miles of 45-55 4 lane highway with 4-5 stop lights, twice a day. Plus a weekend semi-road trip which was mainly 2-4 lane highway at 55-65.

Driving style matters a lot.
In my usual town driving (shopping, school, etc), I get about 21MPG city-only.
A few times since purchase, I took a relaxing drive (25-40mph) on roads along Puget Sound roads with wife.
Instead of going down, the "miles untill empty" meter was going up! I think if I drove in that manner all the time, I could have gotten 25mpg city.
But then again, it wouldn't be fun.

I probably do about 75-80% highway driving with some hills throughout northern/central NJ and am getting 25.5MPG. Computer says my average speed is almost 40MPH. I am consistently going 65-75 on the highway without cruise. I agree with the other poster on here about the sweet spot to really gun the car. You can't floor it if you want the thrust - it's kind of in between. Great when coming out of a toll. WOOSH! So what gives with the diesel gas prices? Isn't it less to process but it's costing more around here in Northern NJ than Premium (like 20 cents). The price thing is probably on another thread, but it's annoying. But I love the car too much to care!

Wrong. Over the next 200 miles, the mileage only changed by .3 mpg lower. If I hadn't been driving over hilly terrain, it likely would have gone up.

Driving for a few thousand miles will include more variables (city and highway) and will have an impact on mileage. But that's not what the OP asked for.
