Do you use the recirculate button or keep drawing cold air from outside.

At 45 you should be in 6th still and doing much better fuel mileage than 65 because of less wind drag and friction. After 60 you're almost always in boost so much harder on fuel, in the winter time you lose volume of gasoline just from shrinkage becaus of the cold. You fill up with 12 gallons coming out of the ground @50°F and 2 hours later you only have 11.2 gallons @-10°F. So there goes 8% mpg right there, then all the CVjoint grease that's like cement when cold, the 2 differentials full of molasses. Wheel bearings, driveshaft U-joint and steady bearing all get harder to turn in winter. Mine goes from 7.3l/100k summer to 9.3 winter. Winter is hard on MPG.
Sometimes I counted up shifts while starting, but never paid much attention. My average MPG somehow managed to show 99.9 (which is in no way correct). I filled the tank, reset the average MPG, turned on my OBDII gauge set, and went to a friend's place. set cruise at 70. flat road boost gauge showed 3 PSI, Tach read a bit over 2100. some minor inclines showed boost PSI between 6 and 7. 18 miles out, 18 back. 22.5 MPG. Idled 6 or 7 minutes before return trip. My normal daily driving rarely gets above 50 MPH and that gets 0 to 1 on the boost. Thanks for pointing this out.

my 2019 I bought new has 35k miles on it. I reset the Average MPG on the dash when I got it and I'm sitting at 29 average which is great because I just moved and I'm about 30 miles away now all highway so it should creep up. Before I was about 6 miles from work and it was all city stop and go.

21.9. Winter Fuel and letting it idle before I go to work. My average started dropping last February compared to this time last year. I suspect it has to do with a shorter commute and a little less time at 50 MPH

good day

2019 awd Trax 2,450 miles currently. Been averaging 20mpg. Is this normal? I hope not. For a little 1.4 liter engine. Seems like low power on the interstate. Takes forever to get up to speed.

good day.. you can get better than that as I too have a 2019 and this is what I have noticed.. I do try to use my cruise control almost all of the time and let my vehicle computer do its job.

When I used regular unleaded 85 octane, I got that type of mileage. Now I use migrade 87 sometimes 91 premium. With 87, I now get between 30 to 35 and with the 91 I average 35 or more and have seen it as high as 43 mpg at an altitude of 6000 feet above sea level. When I go to 5000 feet it gets better mileage.

Hope this helps.

Currently my mileage is about 22 mpg, mostly because I warm it up for about 20 minutes before I leave for work. No issues with highway speeds either, my biggest problem is not realizing just how fast I'm going.
Use your cruise control.

Yesterday (1/2/22) hit a scorching -15F. I used the auto start twice before I went to do a bit of errands. I saw this for my mileage. I realize this isn't real. (Perhaps this post belongs in a different listing.) Today I have 2 for the temperature and the mileage hasn't changed.

Where do you live? Here in Colorado temps have been around 13F at night. I never prestart my car and let it run. I will go out start it wait about a minute or two and go. This will help on MPG. what Octane of fuel are you using? You should be using an Octane of at least 87 or higher. The higher the octane the better the mileage. I travel approx. 22 miles one way to work and will average 28 - 32 MPG in the winter at 6250 elevation. When we go to a 5000 foot elevation, I see my mileage go to about 32 - 42 MPG. I rarely go over 65 mph and maybe this is where I am saving my mileage. I know if I stay around 55, i will get the best mileage.

Hope this helps.

Southwest of Minneapolis. I rarely get over 50 due to my commute. I typically use 85 octane. Thanks for the suggestion.

That would explain the cold temps. When I had tried the 85 octane, I also noticed that my mileage would drop to around 25 and i was not happy with than. So I figure, I will have to pay a little more to get the mileage I feel I should be getting. Try it and let me know if it works.
