30 mpg 4.4
 

Worked a long day today and decided to take it easy on the way home.

In fact, I decided to see what kind of mileage I could coax out of the X.

Over a 15 Mile section of 55MPH state road - with stop lights, I was able to get about 26.7 MPG @ 54MPH.

At 46MPH, I was able to get 29.7MPG. (This is as read from the computer.)

I was impressed that it would do that well.

I tried that once...eking out every ounce of mileage during a trip. It was very hard work! Frankly until gas hits $8 a gallon, I going to just drive it and be happy with my usual 14.9 mpg. :D

it's not accurate until you go 100+ miles.

at least that is what Ive experienced.

The best I've ever seen is about 22 mpg over flat ground, 70 mph, air off. My running average over 10K+ miles is 16.2 mpg.

yeah, I've seen 25+ WHILE IN MOTION, but most of us use actual mileage calculated after filling up the tank (miles/gallons=mpg) - only political spin doctors play with numbers your way:rolleyes: :rofl: :rofl:

My average over 30,000 miles is about 16 mpg according to the computer.

While not great it is not bad considering I drive a fair amount in traffic.

what?? that's great - my avg is 13.7!!!! and im no speed demon, i'm actually careful with accelerating

2001 X5 4.4i sport - 100k

what am i doing wrong? is it the car?

Thats awsome, I can get close to these numbers after I reset the computer...

I am getting 12.9 mpg city driving 03 4.4 with 69K

What type of fuel are you using? City or highway driving?

My 2001 X5 4.4i sport has 104,000 miles and I get around 19.2mpg. Sometimes it dips down to 18.8mpg. About 75% of that is highway driving. I use Shell V-Power (93 octane). And I'm not that careful with accelerating! :driver: :zoom:

For about a year, I was 80% city driving. I was getting around 14mpg.

Don't let the computer fool you. Try resetting your computer while you are going 50mph on the highway. MPG galore!:rofl:

To find your actual mpg, do a full tank fill up and reset your trip meter. On your next fill up, divide your total trip miles by how many gallons it was for full tank.:thumbup:

That's what I do. :thumbup:

Doing the fill up and divide method (actual values, vs. usually wrong values that the computer provides), I seem to get about 17 mpg city/hwy mixed driving condition consistently. (2005 3.0 with 45k miles on it.) I drive regularly, no hard accelerations and no babying it either.

'06 4.4 running '91 octane and I'm averaging 18.2 mpg with mixed city/hwy driving. As long as you don't constantly reset the computer its on par with the calculated value.

i averaged 24 mpg.. ac on and off and 50-53 mph.....

around 70 degree

I find the computer is always shooting high. Upon comparison with actual mileage driven divided by gallons burned (obtained on fillup), I find the computer is always overstating by at least .5 using numbers from a full tank (so over 100 miles as previously mentioned).

:iagree: ...in both our X and our Vette. The tank arith is much more
accurate, imo.

My display keeps displaying 15.1 mpg (over the last two months), and I am measuring 17 mpg, so the computer (if that is what we mean by it) is definitely not showing the right value in my case.

Today i did a run on my 3.0L Diesel and got 35mpg.... Steady 70. Think that not bad. Still looking at getting a bit better. Maybe turn heating and lights off. :stickpoke

I use the miles divide by tank fill up and in winter I average 14 mpg(50% city, 50% highway). In the summer I can get it up to 18 mpg easily. Accelerating pretty hard both times.

gotta love it??

I only use premium 93 octane. I'm going to try doing it the old fashion way like mister suggests, maybe it's not that bad.

Can't remember from the summer but in winter my computer has been saying the same average as I calculate. Well almost same. It is like .1 or. 2 off and I think that is very normal.

So I guess I shouldn't complain about the 12.1 I'm averaging in my '02 4.6; sometimes I actually see the needle move.....

i'd give up 1.6 mpg for 60 ponies

The other thing to consider is whose blend you are using. Some people blend in a bit more ethanol, and with that, down go your numbers.

My fiance rarely drives on the highway. Work is about 3 miles up the road from our home. Averaging 10.3 mpg :D

the only way my 4.4 is seeing 30 mpg is if im going down hill with a south wind on the back of a trailer being pulled by a hybird :rofl:

I don't get when people nickle and dime their X... I just enjoy the hell out of mine. I dont try to squeeze a few miles on my gas consumption.

:iagree:

With gas at less than $3.00 a gallon why skimp?

Funny but posts like this remind me that I should check the consumption on mine once in a while. I have never paid attention. As long as it doesn't break I'm happy.
The gas is cheap, and I really appreciate it every time I come back from Europe where to fill up an Opel Corsa (Honda Fit type) I spend around $130. $50 to fill up my X5 is close to nothing.
