What has been your best MPG/range on your X3
 
I know we have done this before, but what has been your best MPG and range you have achieved in your E83?

After 3 years of ownership of my 2009 and a little over 77k miles I just hit my best single trip MPG and range on a 417 mile trip from Sacramento to Los Angeles. Although I did fill up before I hit rush hour traffic I was on track to a 460 mile range and a MPG of 25.1. My average speed before traffic was 72.1 and after arrival was 64.5 (darn traffic).

My consumption 2 hasn't been reset in 7 months on my nav board computer and it shows a combined city/hwy (mostly hwy) of 22.8.

Highway 25.

100% highway, no rush, trying to achieve good mpg ->28.5MPG
Everyday driving though ( 99% city ) -> 20 MPG

Interesting website, hadn't seen it before. Collects a lot of data for X3's, as well as other cars. Worth taking a look at.

For what it's worth, my best MPG was about 26.5 running about 70 - 75 down I-5 to L.A. Never tested range, always try to fill up before that becomes an issue.

Click the signature..........current tank is averaging 9 l/100km according to the BC using midgrade, no-ethanol fuel.

I've noticed around 70-75 mph seems to be a good economical speed range. I travel between Seattle and Chico, CA often. The mountain passes put a dent in my mpg. I think my best was 24.2.

CleanKM 02-05-2012 06:21 AM

18 city, 22 highway (using gas from AAFES). When filled at sunoco, i usually get 19/23. Overall comp averages around 19.5ish, but i also have a lead foot (high speeds 85-95 mph).

X3-terrestrial 02-05-2012 06:38 AM

Never gotten more than 17/23 and 20 combined, also have a lead foot. You gotta stop thinking about your gas mileage if you want to enjoy your drive! If not, get a Prius! ;)

Usually about 17 in town and 22 on the road. Best speed for my '06 3.0 is 70 mph, seems to be happy there and returns decent mileage. I think the trip down I-5 going south is "down hill" as I always did better going there than coming home mileage wise.:angel:

Evlengr 02-05-2012 07:36 PM

I average 22, but that is mostly highway (at 70-80 mph mind you). On our trips to the beach which is an 8 hour cruise we were getting close to 27 mpg. That was doing about 65-70 and no dramatic speed changes.

I still think whatever they treat the gas with during cold months and the temp itself eats about 1-3 mpg, but that could also be the added heater and ac/defog adjustments.

Those things certainly all contribute. As well as the fuel mixture, which remains richer for a longer period of time after start-up (until the engine reaches operating temperature). It just takes a bit longer to warm everything up during the winter months...

I generally get ~18 mpg in pure city driving; ~22 mpg in mixed; and 25-27 mpg on the highway.

Very interesting that we all get the same ranges of economy throughout the country. I wonder what the true effect regional fuel blends actually have.

gzep23 02-06-2012 05:52 PM

I live on central new jersey and idk of its because I have 135k miles or a lead foot and a 2.5, but my gas is like at best 22 on the high way...if I reset as I'm coasting at 70 to 80 between 2500 and 3000 rpms I get like 26 but idk if thats true. Given I went from driving a Mercedes s500....which I also had a lead foot, but getting 16 highway keeping it below 2000rpms

AzNMpower32 02-06-2012 06:37 PM

Generally with the smaller engined 2,5 litre, I find that above 120km/h (74mph) the fuel consumption decreases rapidly. When I cruise and average closer to 150km/h (93mph or so) I usually get no better than around 20 US mpg (11,6 l/100km) dependent on terrain.

Cloudy 02-07-2012 06:07 AM

19.8mpg combined, still looking for the elusive 20!

gp500 02-07-2012 01:28 PM

Combined during winter: 13l/100km(18mpg)
Best : 7.7l/100km(30.5mpg) on a 100km short trip, 8.3l/100km(28mpg) on a 520km long trip.
Those numbers are with an average speed of about 70km/h(45miles/h)...

jrapo 02-07-2012 02:03 PM

Dashboard indicates 19.0 with mostly city driving. BUT calculating the gas used over mileage indicates 18.5. The nog computer seems a bit over-stated

A lot of the time, I wish I had the newer, more efficient 2,5si engine. But then when I step on the throttle.....it's all okay (prefer the sound of the older M54 engine) :p

My BEST mpg is 24.8, at a "partial" fill-up (took only 8.9 gal). At a more complete fill-up (took 15.7 gal), my best is 23.7 mpg. I've had the car just over 3 years now, and I'm still averaging 21.2 mpg overall, with a daily mix of hi-way and city driving in central Jersey, but lately my mileage has been going down -- only averaged 20.8 over the past year. Perhaps this is due to the new tires, Michelin Pilot Sport A/S Plus (versus the OEM Pirelli Scorpions).

My best MPG over approximately 660 miles of interstate driving at around 70 - 80 MPH has been a solid 24.5 - 25 MPG per the trip computer. Recently I made that same trip, without AC in the cooler fall weather and nailed 28 MPG. All this on ethanol free fuel. 2007 model, 60k miles, new primacy tires, good inlfation/alignment, oil changes, etc.

Dominic49 02-09-2012 05:44 AM

how many of these claims are based upon the trip computer and how many are based upon actually calculation at the pump?

p.s. 11487 miles driven since October 8th when I purchased the car with an average price per mile of right around $.15 for gas and $.05 for maintenance
