Fuel Consumption - Does it improve ?
 

I have had my SD now for 2 months and have covered 2000 miles...absolutely love the car. The fuel consumption is good but not fantastic I would say currently. My previous car was the 535d with the same engine. I am getting high 20's mpg at say 80 mph and probably averaging high teens around town. I would be interested to know if owners have seen their mpg improve with mileage? The engine has started to loosen up a bit more but I think needs 5000 miles at least from experience with my 535d to get the full beenfit of the engine.

Give it 10,000mi for it to get optimum fuel consumption.

What kind of improvement did you see at that mileage from the consumption at 1000 miles?

geez 10k. I'm only at 250mi. after 25 days. I literally need to make excuses to drive more. I'm seeing only 14mpg suburbs so far. Hoping for 17mpg+ one day like the sticker suggests.

I am at 11K averaging 13.2 mostly city. Long-haul trips right around 17mpg at around 75-80mph. i have a 4.8i

don't feel bad...i'm still showing 12mpg on my 3.0 with 800miles!!

highest i've seen it go is 12.4

taken her on just 3 longer highway trips... the rest is mostly around town...

I must use good gas. I drive between 60-70 mph to work (highway) and get roughly 18 mpg on a 3.0si.

You don't get good mileage until your done about 10,000klm and could take even longer. Also it won't be due for one but change out the air filter at 10,000klm.

You will be suprised that by that change alone you will get better economy. Apparently BMW only changes the filter after the 3rd service and that is to long. With turbo's there sucking a lot of air and with that all the city crap straight into the filter.

It wasn't a sudden increase, but rather gradual.

In the US, the X3 was officially given window sticker numbers of 17 mpg urban and 23 mpg highway. (All of these figures are US mpg). In the beginning, our X3 was getting around 14-15 urban and about 20 on the freeway. By 10k miles, it was about 25% better overall.

Today, with 56,8k miles on the clock, urban is about 18 and freeway is easily 28 miles to the gallon. The biggest improvement is obviously the extra-urban driving, since it takes a lot of fuel to get 2+ tons moving!

what's your current total mileage?
