Is 21 mpg highway low enough to suspect a problem?
 

Hi All,

I've got an '06 3.0.

I'm getting about 14-15 mpg around town which hadn't concerned me that much since it's hilly terrain and stop and go.

But I just took my first long highway trip and only got 21-22 over 400 miles with two adults in the car and cruise set at 65.

Is that just life with a heavy car and smallish motor? Or low enough to suspect an issue?

Thnx

I averaged 17mpg highway this past weekend with a roofrack and 2 snowboards on it. I am starting to think it may be a bit too low even with the wind resistance...

:confused: huh?? What mpg are you expecting? You're already getting 2mpg OVER what the car is "supposed" to get:

EPA says 19 MPG highway

Gas Mileage of 2006 BMW X5

Don't know what the speed limit is where you are but I hear there would be a big MPG difference between 55mph and 65mph. Of course, I don't know anyone who actually drives the speed limit. :D

That's about right. You're driving a 5000lb vehicle. I am more concerned about cruising range than gas mileage. 2-4 mpg isn't too significant to me and I really didn't buy a SAV for mileage. I actually get around 19 mpg on the freeway doing 75-80 with a 4.4...very acceptable to me.

Whoops, I withdraw the question.

Had it in my head it was rated at 24 highway for some reason, but obviously 20 looks about right.

i would love 20! I am sitting around 16-17

:iagree:....

I do.... When i'm on I-75 i go 75mph. when i'm on I-80 i go 80mph :D
