Actual fuel economy

[ecanem]

So I drove my x5 tonight and my long term mpg is 19.9 (and it's rated for 19 city) so assuming I drive similar on the two. I would expect 16mpg. I'm getting the mpg equivalent to using e85. I wonder if the cup somehow thinks I'm Using e85 and is adjusting performance.

I am getting 13 MPG in the 15 Denali. NOt as good as I was hopping for but not that surprised either....

I am getting 18mpg through the first 2000 miles. Good balance of city and highway. 5.3L Tahoe.

Never reset the trip on my '07 and it had 15.8mpg at 120,000 miles. So I'm happy so far with the improved engine.

Once you get her broken in a bit it will improve. Also, if you are not run premium to and see if that helps your numbers. Quality of gas can have a lot to do with it.

I get 14-16 in around town with a lot of stop and go. Average about 20-21 at high 70s and 22-24 in the 60s.

Overall average is 18 in 3,000 miles.

We just got back from a 3200 mile trip. Keep in mind no mountains between Oklahoma and Florida but got 22mpg going out and 21.7 coming back. The difference is probably attributed to taking different route there and back. The trip back had higher speed limits. Our previous vehicle was a Volvo xc-90 and it would have done about 22-23mpg but with quite a bit less space. The kids love the rear buckets.

I've too seen 21 pretty easily on highway with a 4x4 Denali.

I have just ove 8k on the XL now and when we went to Florida we hit 23.4 on thr ride down. I average 19.2 day to day driving

Ok. I drove across PA 400 miles 95% highway and got 18 max. Something must be wrong.
