on the way back from Atlanta from picking up my 535i averaging 75mph I was able to get 33mpg for around 200 miles...
I consistently get 20mpg in town in traffic, and my wife says I have a lead right foot.

I really have just now got the car broken in and really have not driven alot of highway. So I kinda expect for the numbers to go up a bit.

Someone posted to lighten your car like removing the spare ....etc., way back....

I also have an xi and tank to tank mileage varies from very low 20ish mpg to mid 20s mpg ... I have seen that easy cruising on a long drive (40-50 miles +) at US-legal speed limits yields very high 20s or even touches 30 mpg. But a couple of traffic jams or heavy go-pedal action and BAM!

No doubt a RWD 530/535 is going to do even better simply because of drivetrain drain in an xi/AWD vehicle.

And while I'm trying to personally conserve a few drops of gasoline, I'm constantly passed by guzzlers blowing by at 20 over the limit ... Every time I experience that, I hear a major "cha-ching" in my XOM holdings Thank you ... thank you ... may I have another!

im right there with you... the best MPG i've seen is 26.5 on my way to Walt Disney World. sucks that the V8's are getting better mileage than the I6's

doing what?

The best I got with my old 550 was 28 mpg hwy doing between 55 and 65 mph on a level surface and being gentle on the throttle. When I wasn't trying to be conservative, I got 25 mpg at best. (Doing the same thing in my M5 gets me 19 mpg when 'trying' to be gentle with the throttle).

I have an 04 545i and easily get close to 30mpg highway. My friend has a 325 and never gets that, which, I believe is due to higher rpms for similar speeds. I have an 08 535ix as a loaner currently and it also cannot obtain the mpg the V8 gets.

I have a Dinan cold-air intake & throttle body, and a Remus cat-back exhaust. When you're not driving aggressively I believe these items can lead to higher mpg as well due to better air flow and less weight.

Yeah but that's no fun!! Seriously, there is a <big> difference in mpg results depending on your level of "enthusiasm". Just for kicks I compared a week of driving the same routes and traffic conditions more or less, driving around in D, to a week driving in S but same style of driving. About 1.5 mpg's lower. I then drove a week in S and had fun while doing it, and another 2 mpg reduction.

A guy told me one time if you're going for mileage, pretend there's a raw egg between the sole of your foot and the go-pedal.... That style will max economy, but again... It's no fun and not why most of us bought bimmers!

I have a 65-70 mile commute to work each way and if I take a detour (which I usually have to because of traffic tie ups) it adds 10 miles each way - so I usually put on 150 a day. Then if I travel... its even more. Its a grind... and I knew it when I took the job.... which is why I bought the 535xi - I knew I would look forward to every opportunity to drive it!!!!! I had a Z4 but given the miles I was going to be putting on it I wanted something with a bit more margin of error in case of an accident!!!!

I have a new saying when people ask what I do. I tell them I'm a race car driver. I race twice a day for 1 1/2 hours in a combination enduro and demolition derby around Boston. In between I sit in an office.

That is basically my drive, about 150 miles per day back and forth. Just like you said I knew it was going to be a grind and decided to get the best driving machine I can afford to enjoy yhe ride.
