I've had my Ascent for a few weeks now and am averaging around 18-19 MPG. I thought it would be better though I am doing mostly city driving. What's everyone else's average MPG?

Thanks!

I'm getting 14.1 city and short highway hops. Ascent Touring one passenger mostly.

My first tank i was up to 23 on the fourth of july when we put about 100 miles on it, most of it highway, but since its dropped to around 20 with mostly around town driving. Only 600 miles so far and just put my 3rd tank of gas in it.

Averaged 26.1 on my last tank mostly highway driving. Mileage seemed to jump up a bit after 1600 miles.

Good to know... I've averaged 19.1 over 700 miles. Was hoping it would get better after break in period.

I'm just hitting an average of 23mpg, and still slowly increasing. I am at 2300 miles so far. Give it 5,000 miles or so...

Just a question. Are you all basing your MPG based upon the car's computer system or are you putting pen to paper and doing the hard math? If you are not doing the hard math, it may be worth trying. If you are seeing something different when you take your trip miles and divide it by your gallons to fill than what the computer is reading, it simply could be something with the calibration in the system. Now if you put paper to pen and are actually getting teens, the question becomes Why? I am not sure why, but about every 3-4 fills, I run manual numbers to compare against my cars trip calculations.

1800 miles on our Ascent and the last tank was 25.3 but doing the math it is 24.4 mpg. 410 mi, 16.8 gal.

As of right now, I'm just going off of the what the car says because I havent filled up yet. But when I do, I'll be doing the hard math and comparing how off it is.

Have about 220 miles on my so far and I am getting an average of 20.5 which is an improvement over my 2013 CX-9 which was only getting around 18.

Sadly, your computer is actually calculating high. I was hoping that for some people, it would be the other way around, to show that the Ascent is getting the mileage that it is supposed to and that something in the software for the car's system is off. The company I work for happens to build spraying equipment and we work with a lot of electronic flowmeters. If the software is off slightly or the meter is not putting out the appropriate signal for it's output calibration is off. I was hoping this was simply a software adjustment.

I'm just under 500 miles on mine, averaging 19-21mpg with a mix of city/freeway driving.

Me thinks thouist might have a touch of the foot of lead ... One thing I hate is watching my average MPG drop after hammering it for a minute or two ... it does seem to really suck the gas when you get on it.

Always the math as I keep track in an app called "Simply Auto" then manually enter them on Fuelly.

Here is a link to all the Ascent vehicles on Fuelly.

If you want to see mine in particular you can view this one.

So...If you're doing the hard math...does it make sense to use the mile markers as your baseline for mileage as well...or a known route (e.g. home to work is 20 miles)?
I'm only saying this because if your trip computer in the Ascent isn't calibrated, chances are that the odometer isn't calibrated as well...no?

Different systems and different sensors (though the data is likely used together for the mpg and range calculations).

That doesn't mean that one or both of them might not be off, but it is least likely to be the odometer/speedometer sensors and calculations.

I would highly doubt that the speedometer and odometer would be out of calibration, but anything is possible. When I have wanted to verify my odometer I generally get to a state highway or interstate and check it against the markers for a few miles. With the restrictions on title changes and everything, I would highly doubt that a manufacturer would release a vehicle without the odometer that is accurate.
