your methods of calculation seem legit. That is REALLY impressive mileage. I would be ecstatic to get that kind of mileage in a 3rd row SUV!

This was very telling. Thank you for this link. Your 'nerdy' research is actually very relevant, interesting, and enlightening.

made a trip to the in-laws two weekends ago for Memorial Day and had the QX60 in 'sport' mode. I would guess probably about 70% highway, 30% back/side roads for the tank I was measuring MPG (although even half of the highway was under construction and traffic was heavy, so not 'typical' highway conditions, I don't think). Anyway, by the time I arrived at the pump, I want to say the screen was reading like 22.1 MPG, somewhere close to that, which was near as high as I've ever seen it by the end of a tank. Did the calculation by hand to check on the accuracy of this, and hand calculation was 21.4. So the screen was inflated by .7 MPG. Not too far off, but not exactly correct, either.


I believe the PSI in my tires are usually 34-37PSI depending on temp and how long I've been driving on that trip. Quick google research indicates that fuel mileage can increase by about .2% (a VERY slight increase, really) per 1 PSI increase in tire pressure once considering the 'normal' range. so whether I have tires at 36 PSI or 40PSI, really wouldn't amount to much of a difference in MPG at all. I have the upgraded, larger wheels. Probably 20" I think. no tow package, though it does have every other option possible. On this trip we did use the A/C quite a bit, both front and back climate controls were on as we had all 4 kiddos packed in the back. So again, a vehicle this size with my whole family in it, I wasn't necessarily displeased with the mileage. Until I see some of these other posters' information LOL Glad Rooster brought me back to the 'real' numbers so I don't feel as bad about it LOL

I bet if you were on ECO mode with ECO pedal on, your MPG will increase to 23 to 24... By the way, what grade of gas you were using? 87 regular?

To whoever is interested, i am happy to report my current 100% non highway commute mpg is 26+ mpg with 26 mph avg (a lot traffic lights). I know it is not a full tank yet, but i just want to share this to everyone. This car mpg is above my expectations.

Just filled the gas. Here is the number: 368.3 non-highway commute miles (Chicago Suburb), on 87 regular, 15 gallons fill up. Dashboard shows 26.5 MPG, hand calculation is 24.5 MPG. Tire 35 PSI cold on 20" wheels.

I am impressed

yes, using 87 regular octane fuel. I think when I am in ECO mode, ECO pedal is also on, as it feels really heavy and hard to depress even driving around casually, I don't think I've ever seen 23 mpg, let alone 24 and that was when consciously TRYING to drive in a way to optimize fuel mileage. That being said, I have not done hand calculations in full ECO mode conditions, so perhaps the real calculated numbers will be better than the on-screen ones and my mileage will actually be in the 23-24 range, though I doubt it. I will give it a try though and see and reply back on here sometime in the future with those numbers

Every time I fill up my tank the range is between 360 miles to 430 miles. How can it be a that wide of a range from one tank fill up to another. Same costco has station and same gas type. Lucky to get above 20 mpg on my 2017 Qx60 AWD. I calculate mileage every time if fill up by mileage driven / gallons filled.

City is pretty poor for us but average about 21 in mixed. Just got 24.5 (computer said 25.5) on a 500 mile trip with 500 lbs of stuff in the car and basket on the hitch and going 75-80 on the highway so was pretty happy.

Here is a prove that OP's number is possible to accomplish. I fill it up yesterday, 363.3 miles driven, 20% Highway & 80% suburb commute, trip computer shows 27.9 MPG, filled 14.23 gallons, hand calculation shows 25.5 MPG

I use 87 gas only, and car is in 100% ECO mode with 35 cold PSI. My next tank will be in standard mode, I want to see if these number possible in standard mode...

Let me know if you have any question
