Also, are you checking real world mpg by calculating miles traveled divided by gallons used for each fill up, or are you simply going by the OBC?

Assuming your dash computer checks out to be reasonably accurate, try getting on a stretch of freeway with light traffic, zero the computer's mpg, set your cruise control for 65 or 70 with the car in top gear and cruise for 50 miles or so (if there is a wind, do 25 miles in each direction). If you don't see at least 28 mpg over the 50 miles, then you have a problem.

My 6 speed 328i averages 28~30 on the highway and 24 overall.

Usually, the mpg reported by the car's computer closely relates to the reported average mph. The lower the average mph, the more fuel consumption. My 328i is EPA rated 18 mpg city (manual transmission) and 28 highway. In practice I can get 30 mpg highway.

This is tricky.
With my previous car lancer, the mileage increased drastically after 10k miles.
My 328i 6MT used to give me 22-23mpg city.
After BMW Perf Exhaust it came down to 21mpg.
I complained to BMW, they checked, no issues found.
Then I audited my driving pattern and behaved properly for 2 weeks, mileage jumped back to 22-23mpg.
If I drive around in Philadelphia downtown, I get 17-18mpg.
Suburbs, I get 21-23mpg.
Highway, I get 28-32mpg.

So I would say wait for a while and check your driving pattern.
This is 6 cylinder car and when you push hard, 6 nozzles pump fuel faster than a 4 cylinder...lol.

This is a good point who choose a car only based on listed MPG. So many factors that influence this. Many people have posted they did not get an m3 in the past due to MPG but I knew with past experience of owning an I6 bimmer that any kind of city or aggressive driving and you kill the mileage and 15-18 is right in the range my old I6 did in the city or any kind of fun driving.

My m3 gets 14 city and 16 combined. 25 freewway. So the real benefit in the 328/335 is highway cruising if you can keep your foot off the gas but if you are someone who really likes to run the car or you never see much of the highway, there is really no difference.

MPG listed is just tricky by manufactuers and testers

Loll. Traffic isnt that bad. The only part of LA that has alot of traffic is around downtown. The thing that suprises me the most is that m3s are getting 12-13 mpg. Why does a 328i only do 5-6 mpg better than a car with more than 400hp. It doesnt make sense to me.

Gets 19.8 on my 330, but I do drive it like I stole it. These cars don't like city driving and stop-n-go. If you can find a nice road, you'll get easy to 30+mpg average (on that section).

Unfortunately N52 is not a power monster nor fuel efficient. I got 22 MPG spirited driving on 335i with JB+ tune. New 4-cyl turbo should be better.

Just sold our old E46 328 sedan, it actually returned an average of 28.5. Great stuff. We have a new addition to the family, an E92 335 coup and I am surprised at the difference in milage. (the E46 was a stick, although we looked for a stick on out new beemer we ended up with the auto)

The new car is averaging 23 so far. Not real impressed with milage, but geesh it is a race car in disguise.

Cheers
