40 LARGE ? I VE SPENT USD 91000 ! AND THE COST / LITER IS 1.3 USD !

ITS NOT A MATTER OF MONEY ! IT IS ONLY IS ENGINE WORKS ALRIGHT

I FULLY AGREE WITH YOU.THE DEALER SAID THE SAME FOR MY PETROL. I SAW 22 FOR THE FIRST 500. ITS GOING BETTER KNOW. I WANTED AN SD BUT NOT PERMITTED HERE. PERHAPS AFTER 1-2 YEARS. KEEP ME POSTED WITH YOUR CONSUMPTION. IT IS INTERESTING TO KNOW.THANKS

funnier still is that "by" was caught but many posts here don't have 3 words in a row spelled correctly.
This thread started out by a guy driving his new X3 down the hiway for hours at 70mph and 4000 rpm. It's turned in to a spell check???
We still haven't got to the root of 4000rpm at 70mph.
How'd I do? Eervytinhg splel chcek OK?

what you dont understand ? 4000 rpm & 160 KM(about).

If my math is correct 160KM per hour equates to about 99MPH
A new car with almost no miles on it, traveling at 99 MPH for extended periods of time = bad gas milage. What you don't understand? This thread has become a waste of bandwidth. Tell us what kinf of milage you get when you get 16,000KM on the X3 and start driving like you want better milage. Doing 160KM isn't going to give it to you.

1st...the car had 400 km or more
2nd... nobody said extended. the oposite. here we dont have such long ways, and the trafic is alway bad. i was able to maintain it for max 5-10 mins, then down to 3500 then slowly back to 3900.
3rd... neither bmw nor dealer have a doubt on that ! manual says no more than 4000 rpm.
4th do you think that going low is better ? as a mechanical engineer I realy think that there is no prob at all. from one side the perfect machining of these engines, the quality of metals and the progress in lube oils will not do any harm at all.
To be honest with you, i dont understand that last 3 lnes ...!
why do you think that bmw gives you 25,000 km for the first oil change???
the times have changed. Let your car breath !!!

Sounds like this guy is determined to drive in lower gears and higher RPM --3500 to 3900 RPM is way to high for normal driving--Just because the manual limits to 4000 RPM does not mean to cruise at 3900 RPM---put the car in "D" and drive (or 6th gear if manual)--Or just drive as you are and quit complaining about gas mileage. :rant:

No one speaks of harm to your engine and no one doubts that BMW engines are engineering masterpieces meant to be driven. You original post had such little info in it that I'm still suprised it went on for this long. Your concern was for gas "consumption" We understand you have a 6 speed, that's not your problem. Keep your foot out of it and watch you consumption go way down, that's your problem. Going "low" is better for mileage going fast is better for fun. Lastly, I don't know why "BMW gives you 25,000 km for the first oil change". I change mine at much sooner than that.
Ok now, I have to go watch the grass grow.

Whats going on here?
Last time I checked and read , all YES ALL SUVs , SAVs consume more fuel because of its weight. PERIOD. NO IFs or Buts AROUND IT. Only way to get around it is by buying a Hybrid or compact cars.

I disagree--most SUV's consume more--the '07 x3 is EPA 18/26 about on par with larger cars. It gets better mileage than the Audi Allroad I traded in--a station wagon--it was rated at 15/23.--in the SUV group it gets good mileage and does not require premium fuel.:thumbup:
