real life gas mileage for X5 diesel

[Gaucho]

2012 X5d 15000 mi
Combined freeway and city 25 mpg
In weekend trips at 75-80 mph highway get about 28-30 average. Some climbs some downhill mostly flat.

In fact my overall consumption with lots of city miles is around 17 mpg, and I believe the engine is the same. Look for gasoline puddles under your car when you park

Weight difference, yes. And keep in mind its NYC, everybody here drive, like they just stole they car. Not mentioning the traffic nightmare. Plus I have BMW tune up, so I have instead of 400 hp i have 450. I guess they just tweaked the ECU.

Gaucho (from Argentina?) I don't believe you, but . . . if true I'm very happy because it means that my 35d will be getting comparable mileage when it hits 15K miles. Did you measure the 30 on the downhill section of the trip?

I get 30-31 mpg on freeway w/ cruise set at 72mph on my 300+ mile trips. Avg 23-25mpg in town. Better mileage than my old 535xi wagon. I love my X5d!

Dated technology only means less problems .

I agree with you and that is one of the big reasons - among many others - I bought my 35d. My Xd does not need an 8 speed transmission, the gearing of the 6 is perfect for the power curve of the engine. The engine itself is just phenomenal and I for one don't feel the need for a better one. Some people must have the latest and perhaps for those the "dated" X5d is not cool enough so they must buy something else - that's too.

2011 with 35k miles and then 2012 with 4k miles, both right at 22.6. 60/40 city/highway.

Was getting 19-20 90% city but since I installed the JBD tuning more like 17-18 now.. What to do??!?!?!??!

I would love some real life figures vs the epa.

Thanks in advance.

See my previous Post on mileage. It all depends on your speed and tach rpm's.
I recently got 29.7mpg driving at 65 mph and a tach reading of 1850.

At 70-74 mph I have gotten 26=27 mpg.

The fuel you use will also impact your mpg.

On mixed driving in city and highway I have averaged about 23-24 mpg.

I documented the 29.7 by taking a picture of the screen so if anyone doubts my statements I would be glad to send them the picture.

With my fill up today my calculated fuel mileage was 10.14 liters/ 100kms which is 23.2 mpg US. This is comprised of 50/50 city driving and highway at 75-80 mph. Needless to say, I am very pleased with this mileage from such a large vehicle. I do use Stanadyne diesel additive which seems to increase the mileage about 10%.

Exactly what I get.

Just a quick question, having 20 inch option wheels with wider tires makes a difference on fuel consumption?

Mine makes 20.1 mpg 80% city with alot of stop/go and short trips.
2012 x5d with 1293 miles.

2012 35d 15 500 miles:

24.7 mpg mix of highway/city = 40/60

This at an altitude of 7 000 ft +

Big + is the range....

Sure will. The 20's are heavy, even more so with the RFT's. Plus more rolling resistance. Not sure of the impact on the diesel, but on my 4.8 I have rarely seen 18 on the hwy, even trying hard. Typically low to mid 17's all hwy.
Looking hard at purchasing a diesel. Love the torque and mpg.

If you read someone says he got 28.5 mpg, that is probably a little bit downhill with no passengers, no cargo and a bit of tailwind If you read someone is getting 15 mpg overall, that person wears lead shoes and does rabbit starts from every stop light. I feel that mine is super fuel efficient and I love to get 500+ miles out of a tank of diesel. My overall mileage is around 21 to 22 mpg but YMWV.

Actually, passengers would help INCREASE gas mileage while driving downhill.... just sayin'

Here's an MPG update on a 35d
LA to San Diego, about 98 mile drive
75-80 mph speed
25.5 mpg
I have 20 inch wheels on my X5d
5 passengers: 3 adults/2 kids
A/C on at all times.

Acceptable mpg considering its size/class.

Folks, don't post the numbers taken from a trip's length of 100 miles. Just not serious, as anyone can get an mpg number they desire by choosing a certain road.
Post your range on a single tank of fuel.
For those new, my 1.5 yrs of owning 35d sums up to this:
460 miles in 90% city driving on a tank of fuel until fuel warning displays (which means there's about 2 gallons left)

575 miles on a tank (until fuel warning) on out of town road trips.

So whats your average mpg then based on your post?

2012 x5d 18k
Avg: 26.5 85%highway 15 city
Love this truck so far, for the power and size I can't complain!

[mastek]

23-24 mpg around town = 50% stop n go 50% Fwy
28-29 mpg on long hwy trips

Computer shows average lifetime mpg 22.9. Average speed 30mph. 80% of miles put on the vehicle since purchase are city driving.

This is what I get for long HWY roadtrips

Ha ha, you wish :-)
That's computer's estimation after you came down Snoqualmie pass. You were probably getting 35mpg while descending form the pass, filled up, and the computer was thinking you would continue with those high MPGs, therefore gave you this rather optimistic MPG estimation.

Drive to Spokane and back, then let me know if you made it on a single tank of diesel (you can easily do it, btw).
