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.

It should do around 0-60 in 10 seconds. You must have a problem like maybe boost leak, I average 27 mpgUS and a lot better in summer.

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.

Yes I tested mine when I had that crappy Trifecta tune. When it didn't work they had all these theories why. One was boost leak. So I made myself this contraption to measure boost leak.



It didn't leak so they went on a different theory. lol Don't fall for their sales pitch, they are thieves.

I have a '15 AWD. I reset the MPG on the dashboard last June and left it. My commute to work is 5.5 miles 1 way and I usually have a stop after work. I peaked at 28 something during last summer. End of January the average is 21.7 MPG. I do start the engine before and after work, and let it run about 5 or 6 minutes. I don't know what the ideal speed is to get maximum mileage. However, letting it idle will lower your average. If you tend to drive slower in winter due to ice and snow, that may lower it also. (65 in 6th gear may not be the same as 45 in 4th.)

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.

Yeah no that sounds like there’s an issue. In the summer i’ll get around 32mpg and so far in the winter i’ve been hitting 29-30range. I had an issue with my coil pack that made it sluggish and then misfires occured along with gas mileage tanking to mid 20s... keep an eye out for that i suppose but it would be highly unlikely at only 3000miles. keep us posted!

I don't know. I have approx 2,500 miles. Filled up now:
Fuel range 166 miles left. 5 buttons left on gas Guage. Just now at 5 buttons. Driven 79.2 miles since fill up. I calculated from that 17.51 mpg. I just wish I'd get better. Wires Trax got in the summer 27/28 average which I'll take. I hope I can get that too. I know it's not summer but I'm just saying.

Just filled up. Put 6.65 gallons of gas in and drove a total of about 103 miles. So about 15.49 mpg?

Not really. Is your gas tank leaking or are talking about a 3/4 tonne Chevy Silverado? Is your turbo working? Are you delivering mail in a rural area? You should be getting minimum 23mpg. What was your average speed? Something very wrong...

According to the dealership it is. He said it's due to the cold and to wait until it warms up. I'm in central Illinois Temps have been around 5 degrees average lately.
