Gas Mileage 2012 X5 35i

[waqiidepp]

Guys, I have a quick question regarding gas mileage on 2012 E70 (35i) with Msport. No matter what I do my average gas mileage stays below 14mpg. City and/or highway driving. Is this normal. I remember getting close to 16 mpg but the only thing I can remember is the dealer changed my catalytic converter a few months ago. Do you think that could be the issue ?

I get almost 18mpg on my 50i. Not a ton of freeway driving either.

Mixed sitting in traffic, wife is getting 16mpg.

Idk how much miles per gallon but I'm at 16.2L/100km with a Stage 1 Tune

[mitch808]

Are you doing actual math, calculating actual miles driven and gallons filled? Or just going by the display value?

[waqiidepp]

I get around 300 miles on a full tank which is 22gallons. and its says the same on the instrument cluster too. i reset it after every fill

[racermp]

Display value says 16.x mpg.

I go by math usually. The few times I filled up, it was between 300-310 for 19.xgal fillup. Boarder line 16

[waqiidepp]

Do you all have Msport with the wider wheels ? I know that can affect the mileage a little

[Klimo]

wow. I'm getting around 370 per tank. I just hit 400 for the first time, but that was all freeway miles and the needle below the mark.

to make everyone feel better, my display is 12.3mpg

14.54 MPG

16.2/3.789 = 4.30 gals
100kms/1.6km/mi = 62.5 miles

62.5 mi/4.3 gals = 14.54

Wow, glad my wife went with the 35d. Over the last 22 months and 35k miles of 30/70 city/highway mileage is 26.4 mpg. Hand calulated. On average, she's getting over 500 miles per tank.

WOW... I guess I am the lucky one here. 35i and Premium and I get around 22-24 depending on my driving. 80 highway/20 local

Coming back from staying with the outlaws for Thanksgiving, which is roughly a 2.5 hour drive, I got 22.x mpg. Around town, that drops to 18 for me.

The fuel you're using matters, I recommend using diesel.

My thanksgiving trip was a round trip from SF to Sacramento and got 29.4 on the way back. 26.7 on the way there. 110 miles each way. 2 adults, 1 infant with baby gear and some bags. Tire pressure set to 41/48. I have 20s, run-flat, and 3rd row.

I get about 12mpg in my 50i. Almost all city driving.

So its all downhill then???

[rusty_g80]

I tried driving without going above 3k rpm for a couple of days and still couldn't get above 14mpg. I don't know how people get 18 in the city driving 50i. Do you guys reset the counter every so often?

On a short stretch between corpus Christi and san Antonio I pulled in behind a couple sheriffs deputies running 90+, reset mpg, and saw constant 21-22 mpg at those speeds over 25 miles. Loving the diesel mpg.
