We just traveled from S. Florida to Sugar Mtn over Xmas. Great car, great riding comfort! Distance ~ 1500 miles. We averaged 20.4 mpg!! Bummer for a bimmer! I expected at least 24 mpg!

What are others experencing??

Thanks

17 in the city, 21 on the highway. Most tanks of gas are coming out at around 18 mpg based on mostly city driving. One caveat, we live in Pittsburgh which is an extremely hilly area.

Like you, I was hoping for a little better mpg - especially now with gas hovering around $3.50.

How many miles on the SAV?

My drive consists of 20 miles highway and 10 city one way to work.

The first part is usally 80 mph and the second stop and go 5 - 35 and get 22+.

On highway at 65 - 70 it has reached 26 mpg.

Wait till the engine breaks in for lower fuel consumption. It'll slowly increase, and by 10k miles you should be happier.

On a highway trip down I-85, I got 23 miles to the gallon, average speed was 84.6mph. I'm not joking.

On a trip to NYC, with roads clogged with traffic, I got 27.8 miles to the gallon, average speed of 50.6mph.

The above consumption figures are slightly corrected for the "optimistic" calculations produced by the computer.

Im getting about 20.6 mpg with combined city/highway. I also have a manual. On a trip to Nashville, about 2 hours away and over some mtns, I averaged about 26mpg at 70mph. This is in a 2004 3.0. A 2008 has the newer N52 engine. That is supposed to be more fuel friendly. Its probably just a break in issue.

You probably had a low average to start with maybe around 16-17mpg. Then with 1500 miles of hwy miles (around ~23mpg) your average would be around 20mpg. To get a real idea of hwy mileage, you have to reset mpg average by holding the button down on the stalk to reset.

I have 11000 miles on my 2008 X3si. Have not ever reset the mph or mpg. Mixed city, highway = ~45mph, 19.3mpg.

Bobert - to reset, do you press the stalk till it displays the thing you want to reset (i.e mph or mpg) and then press and hold?

Has anyone noticed change in mpg after any of the below:
First oil change ( any brand ? ) and break in period (above 10K Miles)
Gasoline Grade (Octane 87 to 91 or vice versa) and Top Tier Gas
Any fuel additve or mpg improvement service (eg: Fuel and Air induction ?)
Change in Driving habits / Low resistance tires.
and so on ....

Star, yes to increase in MPG after first oil change (6500) and further increase after reaching 10K. Decrease after airing down tires (for ride comfort - helped a little) from max pressure. No difference between premium and midgrade gas that I could discern. Current MPG avg for city/highway is 17/23 in '06 A/T. I have gotten as high as 28 mpg with hard tires (and a tailwind!) on I-5 at a steady 75.

Not to start another octane thread, but don't use regular. It does raise fuel consumption and your engine won't run as smooth, esp. at higher speeds. Some nitwit did this to me at a NJ Turnpike petrol station, I felt a difference, then checked the receipt that confirmed my fear.

Fuel additives don't do anything. I don't bother. To clean out any potential buildup, I use reputable quality gasoline and occasionally do a couple full-throttle runs.

Driving habits make the biggest difference in fuel consumption. Sudden actions in brakes and throttle adversely affect it. I keep the tires inflated a bit above the recommended pressure, at 34psi front and 38 rear.

2008 X3 w/AT, less than 700 miles, hasn't beat 19.2 yet. Driving over 80MPH definitely drops the mileage.

Lance Alot
01-08-2008, 10:20 AM
I averaged just below 19 mpg on my ED, and I put 600 miles on a 2008 X3. My average speed was around 45MPH, but it was a range of city driving to over 110mph on the Autobahn. My E46 got better mileage after breakin, so I'm expecting the same thing on the X3.

I got 20.6 miles to the gallon on our loaner X3 that had 5 miles upon um, "delivery" for one day :rofl:. It was 50/50 stop and go, highway mix. Oh, and some mildly aggressive right foot to test for any transmission problems.

I did a first road trip during christmas time in canada under a -10 celcius and, with 50% at 115 km-h and 50% at 95 km-h, I have got almost 31 mpg (its canadian gallon so, deduct around 20%)

By the time I got to 15K, I was getting ratings that were around 3mpg better. I'm expecting similar improvements in the X3.

01-12-2008, 02:12 PM
Just came back from ED for wifes X3. At autobahn speeds of 100 miles, average of 75, the X3 provided a 19 mpg average. On hilly byways, about 20, however I reset the trip computer several times from city to city and in some parts due to traffic you had to go at 60-70 MPH, at that time I got 25 MPG. I have 335 coupe also, and just passed 8k miles, it was like a barrier, after that the car start giving 3 mpg better. So just wait, it will get better. I was also expecting better mileage than my twin turbo, but is a different engine, transmission, weight, all wheel drive, etc...

Good Luck with your new X3, ours will be arriving soon, I hope.

I am averaging a little over 300 miles per fill up. during the winter months for some reason that is down from the summer driving months when I was getting 350 miles per fill up, werid.

I do have a question, what should the tyres psi be? will softer tyre pressure give you better or worse gas milage?

Donn
01-18-2008, 02:54 PM

More tire pressure will give you a better mileage. I personally use a maximum of
0.2 Bar = 3 PSI extra in my tires, I for myself would not exceed that because it alters the handling of the car.

With only 3,000 miles so far since April 3, I found that around Long Island I was getting a little over 19 mpg, and recently on a trip to Buffalo and Niagara Falls, we were getting 25.5 for the trip. Coming out of a Touareg V8 where I was getting 11 to 13.5 around Long Island, and if I was lucky, a bit over 18 on long trips, I am quite pleased so far.

And I am not babying the X3 either. I think the MT helps as well.

I'm gettin pretty good mileage from my CPO 2005 X3. Average 22 mpg (mixed driving), 18-19 city, 24-25 highway (depending on driving style). I tend to drive around 70 on the highway. Premium gas only, of course.

Bobert
05-26-2008, 06:42 PM
With 2007 3.0si (auto) ~19.5 mpg in pure city driving, and all highway 29 mpg at 65-70 mph. This is with lowish tire pressure at 30psi.

Probably @ 35 psi would gain ~1 mpg -- but the roads suck so we run slightly lower pressure.

Sonoman707
05-26-2008, 10:27 PM
With a 33/33/33 mix in my '04 3.0l averages from 20 to 22 on any given week.

The breakdown being 33% stop-n-go commute, 33% city and 33% @70-75 MPH on the freeway (when it actually moves).

Had some good numbers on trips to Palm Springs. 27 MPG on I5 well above the speed limit most of the time.

I routinely get 28.5+ on 180Mi r/t's from Northern Jersey to the shore; 30.3 was the best so far w/ cruise set at 65 and about 600lbs total load. Around town is 20 using 1-3-5 gears on the 6M. Some may think I'm lying but the computer says the numbers are real. For those who buzz along at 80, you'd too would probably get what I get at 65. I'd like to do the 80 thing but not at the expense of my license or life.

...had just reset the ODO after a refill, but left the MPG on during a long, recent PA TPK trip from Harrisburg to the area of Meyersdale and Sand Patch to do some rail-fanning. This also included a fair amount of offroading (hey, that "hill descent" thingie actually works!).

First 10K mi: Averaged 21 overall w/o reset.
Improvement: After 10K MPG up to 23/24 on hwy, occasionally up to 27.
Gearbox: Manual.
A/C: On and off.

Zac, I agree with maximizing effiency; here's my protocol for my 08 X3 6M:
1. Keep momentum linear as possible. 7. Use few gears as necessary.
2. Use brakes little as possible. 8. Keep onboard load light as possible.
3. Use cruise when possible. 9. Pretend an egg is between foot and gas pedal.
4. Anticipate light changes. 10. Avoid lane jumping.
5. Tire pressure +5 over recommended. 28.5+ hwy, 30.3 best; 20 city 1-3-5 gears.
6. Keep revs 2500max. bobkap

If you are only taking your revs out to 2500 rpm, then it sounds like you might be lugging your engine on the upshifts to 3rd and 5th.. not sure that's healthy for your engine, and worth saving 0.5 mpg... Going directly from 3rd to 5th wouldn't be bad, if you were already at cruising speed, but I wouldn't skip 2nd gear on a regular basis...

I really like #2.. that is what I concentrate on the most.... that pretty much ensures that you are doing the rest of it.. I'm not sure #7 is helping you that much..

Just my $0.02..

Those are imperial gallons. One must minus 20% for U.S. gallons. So around 26MPG is more like it. :)

Also, drive the X3 at 65MPH, not 80. Fuel economy should increase 3-5 miles per gallon.

Some of you folks have lead foots. As a result you are getting X5 6 cyl mileage.

Has anyone noticed change in mpg after any of the below:
First oil change ( any brand ? ) and break in period (above 10K Miles)
Gasoline Grade (Octane 87 to 91 or vice versa) and Top Tier Gas
Any fuel additve or mpg improvement service (eg: Fuel and Air induction ?)
Change in Driving habits / Low resistance tires.
and so on ....

My X3 is not yet delivered. It's possibly being carried by NYK Lines on the Singapore Express with expected arrival to Long Beach on 6/13. Is it Long Beach?

Based on another car that I have kept careful records...

After first oil change? Unknown. Data: 9/19 fill-up 26.9 mpg on previous tank
9/20 first oil change
9/23 28.5 mpg (higher)
10/7 24.6 mpg (average)

10K break-in period? Yes, lower economy; 19.9 mpg-28.5 for the first 3000 mi., 27.2 on the next 15,000 mi.

Additives? No experience.

Non-Top Tier? No experience.

Octane? Yes, EPA rates 1 mpg better with premium. I noted 1-1.5% better at 93 octane compared to 90 octane. 90 octane was a mix of 87/93. At 91.5 octane, there's a 0.5-0.75% better mpg than at 90 octane. I used the same brand of fuel and mostly at 1 station, occasionally at a 2nd station, and rarely at other stations. The type of driving was constant over 1 year. Bottom line is that you cannot justify the higher cost of premium by better fuel economy although you do recoup about 1% or 4 cents a gallon vs. mid-grade. You may be able to justify premium based on higher performance. Note that I did not test mid-grade but mixed regular and premium. The lowest the octane rating in the tank was 89.66.

With gas prices higher, I plan to use no higher than 91 octane obtained by mixing 92 and 87. When I drive on 90 octane, I save about 8 cents a gallon compared to 92.

I still keep careful records. In the winter, I drive on 90 octane and 92 in the summer. I always use one brand of gas but every two years, I drive about 3 tankfuls of another brand of gas. Very compulsive!

I don't rev past 2500rpm in any gear under normal acceleration. Of course, this is with an AT and torque converter, but it gets you how leisurely I accelerate..........:D

(Of course, when needed, I use more throttle. I don't hold up traffic for no reason)

Evlengr
05-29-2008, 08:19 PM
Hahaha I have never shifted under 3,000 and normally shift at 5,000.

My AT typically shifts at 3,000 without pushing it.

Then again I have topped this thing out already :eeps:

However top speed for me has been over 150 mph (not in this).

If I wanted to drive like some of you folks I would have gotten a Lexus and driven slooooooooooooooooooooooooooooooooooooooooow. :rofl:

Vodka,
This is an ongoing experiment to see how many mpg's I could wring out of my X3 6M, not necessarily my general driving style. Generally speaking, I think getting ~30 mpg hwy and 20 city from a >4000lb performance machine is quite a feat; agree?? If I'm not in the mood to drive like an "old lady", I'll jump in my '72 Tii,'80 B6 Alpina or my '65 GTO Tri Power and happily make the Arabs allot richer.

I was driving my dad's Mazda mx-5 today in my usual driving style around town, which is optimised for minimum fuel consumption. This means light throttle, and staying in gear at all times until revs fall below 1500rpm when braking for a stoplight.

My dad was like "you need to push the gas pedal more. You're probably only using 40%"
"Actually, more like 15%" (the mx-5 has a jumpy throttle calibration)
"You're accelerating too slowly. Someone will run into you."
"Well, they can pass. I'm trying to minimise consumption"
"You're in a sports car. Stop wasting your life worrying about saving on fuel."

I bet some of you think just like my dad............
