Does gas mileage improve after a certain mileage?

On Audi boards/forums, it is well known that gas mileage will improve after 10,000 miles. I experienced a 3 mpg increase in gas mileage between 10000 and 12000 miles at 77 mph steady cruise in my 06 A3 3.2 Q. My X3 gets about 23 mpg at 77 mph. Will this improve at some greater mileage like my Audi?

Yes. After about 10k miles, fuel consumption gets a bit better. 3mpg like your Audi is reasonably likely.

I can confirm that too. Around 10K miles I noticed a jump from 23 mpg at 70-75 MPH to 26 mpg. City improved also, but only around 1-1.5 mpg. I have to work at it to get 16 in town. If it weren't for the terrible programming/synchronization of the stoplights here in Ft. Worth I'm sure it would be better. I'd swear they think because there's a light at an intersection they HAVE to make you stop there, even if there's no other traffic from any other direction.

I noticed a small in town (.5) increase after our 04 had the transmission software upgraded. If you haven't had your pre 07 transmission reprogrammed you might want to check it out.

I actually made 1 of those lights on Hulen St that's ALWAYS RED, but on the way home the REPAIR truck was there correcting the problem.

...correcting the "problem"...

I have studied and learned the stoplight timing on most of my main routes at various times of the day and that helps a lot on mileage. There's one area on Camp Bowie that if you do the speed limit you'll stop at every light. But if you do 23 mph from this one light, with a really slow start

, you can make it through the next without having to stop but then you have to speed up to at least 45 to make it through the next two. Only problem is the speed limit is 35!

On the programming thing, I'm pretty happy with the way it is and I'd rather not have to go through retraining it!

Thanks for the tip though, neighbor!

I stopped paying attention to those signs awhile ago. I find it easier to just pick a speed (in km/h) I feel like going at the moment and seems appropriate.

My X3 gets way better mileage than my CLS! I can go all week on one tank of gas in the city. With the CLS, I had to refuel every other day! Although both use premium, I get to pay less overall for the Bimmer at the pump and go farther per fill.

I got a whopping 28 miles to the gallon today driving on mostly flat land back from Charlottesville, average speed was 52.6 mph. A moderately slow car in front of me prevented higher speed (or fuel consumption).
