Gasser real world fuel economy

[JoeyD]

Stock Sport S, Auto, with Willy's Wheels and KM2 tires, normal tow package
week day mixed of city/highway I get about 16.7mpg, freeway averages 18.5 to 20. I noticed that somewhere around 75+ (in theory........ ) the MPG starts to tank

When I had the stock Sport S tires I was averaging 19-22

I drive what I would think is average, I don't try to hyper mile (in the real context) but I do watch myself usually with the daily drives.

With my stock Mojave I was averaging about 15-16 avg total. I do a lot of hilly street driving which kills me. Getting like 10-12. Highway cruising at 75-80mph I’m getting 18-22 easy. Just changed my 33’s to 35’s and haven’t noticed any major change in mpg yet. I’m curious to see what happens.

Fuel up is the app. I've tracked every tank of gas so far.
Mpg stuff is fun to me I try and do it like a game. Even in my little 4cyl car I had I'd try and see what I could squeeze out of it. If I were to do it all over I'd probably do a sport diesel.

I tried to find it but fuel up comes out as a Kroger app…

Stock Gladiator with an Alu-Cab canopy out back.

I get 18 to 18.5 in mixed local driving and between 20 and 20.5 on Highway trips.

The altitude affects mpg too.
In Colorado area at 7000 alt the hwy avg was 22.8 even hitting 23 once at 70.
Thats running back and forth between same points.
Central Tx dropped to 18.2-18.8mpg city hwy 20-21 range.
Running 33" AT3 4:10 with 6spd.

Completely stock Mojave with a/t's, drive slower than grandpa, easy acceleration, mostly highway but some city. I'll turn off the climate control just to make sure the start stop kicks on. My best "average" 16.6, current 15.4. I have no idea why I dropped 1 mpg average overnight either, just got in the next day and it had changed.
I'm still under 2k miles though and it was only getting 14.x.

I have a stock Mojave and do the exact same thing mentioned here and getting 16.6 so far. I took the doors and tops off and drove around town and it dropped to 16.2. I have only had mine for 4 days so far, but that’s where I’m at.

It gets better with miles to a point. Mine was much lower the first 6 or 7 thousand miles, then I noticed a bump up. Of course then I put on A/T tires, added 150 pounds to the front and the dealership flashed the ECU because others were having issues and my VIN apparently matched some pattern (even with no issues) and that dropped it some.
Still, for a vehicle the shape of a concrete block standing tall in the air, and following the 'wind tunnel? We don't need no damned wind tunnel' design, it ain't bad.

Just did a trip from Scottsbluff Ne to Breckenridge Co last night had a 16 avg. and I was at that before heading up the mountain. Bone stock Mojave with MTs and 1400 miles.

I don’t get it we are road tripping now from Texas to California and getting 10mpg as we speak. Never really noticed until now trying to figure what could be wrong?????

21 Sport, 285 75R 17 tires, Quadratec steel bumper and winch.
From central Alabama to Northern Indiana I got 21.1 mpg.
On the way back, fighting a headwind most of the way, 18 mpg.
Not bad for a 4X4 pickup loaded with passengers and essentials.
Can't complain.

I am either puttering around a little town or blasting down the highway. I do need a re-gear. 35s on 3.73 is getting me about 6.7 mpg. Maybe 7.3 on a good day. Obviously that's a joke but it's not not good.

My Rubicon on 37s with 2.5" lift is averaging 13.6 and I'm watching my throttle. On my next fill up I'm gonna see what it actually is if I drove it freely (without looking at the mpg meter).

 

[brancky3]

I track mine on Fuelly every time I fill up.

2020 Sport S automatic
Stock for all intents and purposes that would relate to fuel mileage. I live in a rural area and drive around 15 miles each way to work, but that drive does cross two school zones so it's sometimes stop and go. I only drive highway on road trips.

Total miles tracked: 14912 from 47 fuel ups
Average MPG: 20.0
Best MPG: 24.0 (this was a 9 hour drive from OBX > home last week)

I'm putting on wheels & 285/70/17 KO2's tomorrow so I am curious to see how it will impact fuel mileage

Going over 65 mph? Plus either going into the wind or a strong crosswind??

I see 13mpg all the time "on flat land" if the answer is yes to both of the above.
