First off, I want to say that I am SORRY if anyone has started this thread, please don't brand me as junk or rubbish. I have searched part of the forum, but there are just too many pages. I found one similar thread, but he wanted to know about an '04 mileage.
My question is, what mpg's are you guys getting on the '07-'08 4.8i? post the mpg's on the 3.0is too, if you don't mind.
Thanks!
By the way, I am getting 8.2 mpg after 56 miles of driving on the road, and a few miles off the highway.
hmm...thats interesting. i hope my mpg 'evolves' to a better one. I drive ferociously, as I fly off the lights, and averages 40-50 miles on the road. I just could not resist the power of the engine roaring before me. I hope that doesn't destroy my mpg.
Same here, my 4.8 with 40 miles aver. 8.2 street only - kind of crazy. I could imagine when I will start pushing it to 6-7K rpm, it would probably aver. 5-6mpg - no fun
I recommend giving your engine some time to break in...I no longer have my X5 (an 04 4.4) but the mileage improved considerably once I got over 1000 miles on the odometer.
My lifetime average on the 04 (I never reset the second trip computer) was 18.8mpg (combined city/hwy).
The 4.8 in my 650 was somewhat the same....Early mileage really sucked (though not nearly as bad as you report, but there are obvious vehicle differences), and then improved with time. Also, watch your oil usage CLOSELY in the first 1000 miles.
1,611 miles and my wife (a lot more gentle with the gas petal than I) averages about 12.1 miles. she usually drives the kids to school and to the mall. We have not gone in a road trip yet.
Wow, I'm getting 19.5mpg city in my 2007 X3 auto, sounds like the X5 is almost the same. I get 22mpg highway going about 75-80mph. Damn, I should be driving an X5!
just came back from vacation house 125 miles away, with 22.6mpg from house to house. x5 4.8 with 400miles , the only thing - very very light on a gas with speed 65 max, most of rpm in 1500-2100 range :thumbup:
Of course wind direction plays a big role in mileage. On a state 2 lane highway at 63 mph I recently got 25.7 on my 08 3.0 with a tailwind of 15 or so. Headed back the other way I got 21.3
Our 08 3.0 si is returning about 12 mpg overall now at about 1700 miles. We have not taken it on a trip, but in highway driving around town it has been returning about 20 mpg. Unfortunately, most of the time the car is driven 6 miles back and forth to work in DC traffic, true stop and go. I suspect in this driving it is only returning about 10 mpg since with every tank there are about 40-50 miles of highway driving at 18-20 mpg and an overall average of 12. Not good, but essentially the same as what we were getting in our 03 Honda Pilot. If you look at Consumer Reports for their city mileage you will see that even small cars get awful mileage in true stop and go city traffic. The only SUV option that we considered that would have probably been better in the city was the Highlander Hybrid, but that we did not like the way it drove or the cheap feel of the interior (acres of fake wood on the dash and console). We look forward to the BMW diesels and hybrids to come that will improve the city mileage.
i have been flogging my 4.8 this week. madass passing in 45 mph zones, downshifting and lane changes in DS mode. expect i will get 300 / 320 miles to a tankful. hopefully Johnny Law will not sneak up behind me. damn unmarked Durangoes.
