Yes, I reset the gauge after every fill up, and I also compute the MPG myself, based on how many gallons I just pumped in and what my trip meter says. On my last tank, the car said I got 17MPG, and my calculator said I got 16MPG... Either way: the 330i gets horrible all-city gas mileage.

Had enquired with my CA on my poor gas mileage, as you recall I was experiencing 14-16mpg on mostly city driving loop. Undoubtedly painful with current gas prices.

Well, not much can be said as the car was not producing a fault code, so they chalked it down to the use of ethanol in gasoline leading to poorer gas mileage. I have been using exxon and mobil gas for some time but perhaps a change to one of the top tier recommended gasoline might help....I'd recommend the same to others in the same boat.

I use Chevron exclusively. I still get ~14MPG in all-city driving. In California I don't think there is much of a choice for non-Ethanol or even less-Ethanol gas.

same type of driving with a lead foot, and i get 21.5 mpg in my 325i steptronic according to the obc. i was getting around 22.5 during the winter and spring months. i guess the drop is due to the warmer weather and ac usage.

iirc, the first month i had my car, mpg was really crappy too. gotta give it some time.

Who cares? Why on earth would you buy a BMW to bitch about fuel economy? Most americans buy SUVs that are much worse (maybe not my wife's RX300 gets 19.8 and my old Ford Escape 17 (city only)0.

Buy a hybrid. Gas is cheap anyway, I probably spend just as much per week on coffee

I didn't buy a BMW for fuel economy reasons. However, I did buy it expecting to get more than 14MPG. I wasn't expecting good fuel economy. I also wasn't expecting super-horrible fuel economy. 14MPG is super-horrible. 14MPG is also not mentioned in any of the sales literature

I get about 20.4 mpg on the computer. I reset the computer each time.

I did notice if I drive fast, the MPG will go up, too bad there are traffic all the time.

For those new to this thread and just reading the newest posts - I get super-horribe fuel economy during all-city driving (95-100% = 14MPG). During highway driving I get 25 to 30 which is nice. Unfortunately I almost never spend more than 5 minutes on a freeway.

I'm 100% with you on that

I can't say driving style is to blame (its on auto and no DS & manual-too rough in stop and go) and non-aggressive driving in traffic. Also, I do not think a/c usage is to blame, most of the time is in the cooler mornings and evening so no need to blast the a/c.

Either way you cut it 14 mpg is bad, especially for a 3.0l 6-cyl compact sedan.

Just checke dthe G35, 17mpg in city only driving. I drive with total disregard for fuel economy so perhaps your bmw is broken with 14?

i still manage to get 22-25 MPG city/freeway combined. i get less than 20 when i always try to accelerate fast. maybe people are not efficiently using their gears for the MT. i dont know about the step.

In my case, the break-in procedure was adhered to and the tire pressures are as per OEM specs. I am debating whether to do an early oil change at 7,500 miles-halfway point (my oil meter says I'm down a 3/4 qt anyways at 4,500 miles on the clock). Perhaps that might help. Or maybe I should increase the tire pressures. Or definitely switch to Shell...

To add my 14-16mpg city driving while babying the accelerator...

I'm a huge Shell fan. It was Optimax in Australia and of course V-Power here

325i with manual tranny.

Recent 600 mile trip (all highway) with 2 adults and 2 kids and a Thule cargo box on the roof and got 30.1 mpg (computer said 30.5) while averaging 75 mph.

Yesterday I drove just under 100 miles (all highway) with the two kids in the car (no roof rack) and tried to get the best milage I could. Averaged 55 mph and got 35.3 mpg (calculated by computer).

I'm quite happy with the highway milage. I'll get back to the city in 5 weeks and will check the city milage then.

Yup. I just finished a pair of 940 mile drives, average speed 77.9, 29.9mpg/29.6mpg for each direction. Maybe 20,000' of total elevation change. Top speed was 122, and included maybe 30 miles of city crawl on each leg.

On flat highways, my 330xi will average ~33mpg with cruise control on at 85mph.

FWIW, I have my tires inflated to the "high speed" setting of 35/41. That might make a difference, since higher inflation results in lower rolling resistance.

I have a 325i says i get 19 city and 28 highway but last time I did a 300 mile road trip i calculated around 30mpg going between 85-95 Mph And if you have a Bmw who cares how much it burns as long as it still goes when you floor it

Expected better Gas Mileage

I previously owned a 525i (2005) and was getting average 19.2 mpg (70% city/30% hwy), and 29-30 mpg hwy only. With my new 2011 328i (only have 500 miles now), I only get 14/25 city/hwy. I realize its a bigger engine, but also a lighter car. The dealer said it will get better when I get around 5,000 miles. Also, said the tire inflation is the key factor in improving mileage. He also indicated that what I am getting is typical. For a test, I used the cruise control set at 75mph, and did a 20 minute drive each way on the freeway. I will try on a longer trip later this month, and see what I find. It would be interesting to do a poll of owners by State and see what each comes up with for the same model/engine.
