X5 35d Mileage

jwscfa · #1 01-17-2009, 12:24 PM

I took delivery in Georgia of my X5 35d on December 11, 2008. Since delivery I have put 2000 miles on the car and averaged 24 mpg split as 60% highway and 40% city usage. This is calculated mileage versus the car trip computer which on my car seems to read about 1.5-2.0 mpg higher than the calculated number.

hi, congrats on your new car. i always heard that actual mileage are a few mpg above EPA estimated numbers. and since it's a new car mpg is normally a bit higher until it's fully broken in...? still, 24 mpg is great for a car with that amount of torque

My diesel said 21.9 for highway use. When I filled it up after some city driving on that same tank, I got 18.2 MPG, but I don't think the dealer filled my tank all the way full.

I went through another 1/4 tank and filled up with just city driving and got 16.1 MPG. It's been really cold here, so that has something to do with my mileage. We also use a winter blend of diesel here as well.

I use a calculator to figure my mileage. My trip computer in the car is also higher than my actual fuel mileage.

Keep us posted on your mileage and I will do the same. The shop foreman told me, it would take 5-6,000 miles before the engine is broken in. My engine is really tight right now.

A lot depends too on your length of journey, especially in cold weather. It'll probably take in excess of 11 miles to get to full operating temperature when it's cold. During this time, the fuel economy is dire. I noticed too from one of your earlier posts you commented on the fuel consumption at 80 MPH. Keep an eye on the real-time fuel consumption gauge, you'll spot a significant difference between 70 and 80 MPH.

Thanks, what's strange, there is no temperature gauge in my car. Does the European version have a temperature gauge? I have noticed that the further I travel, the mileage on my computer goes up. I will look at consumption the next time I travel on the highway...

The european version doesn't have a temperature gauge either.

Thanks, I find it strange there is no temperature gauge. First car I've owned without one...

yeah it's a bit annoying

You guys should really avoid highway miles during break-in. It's bad for ring seating. And your ring seal will affect mileage and oil consumption.

I didn't have a choice, the dealer I purchased from was 110 miles from my house... This is my 4th BMW and I haven't been able to purchase any of them locally...
