What gas milage are you getting?

[ShadowsPapa]

Well my "JT" MPG reads that I get around 23 + MPG normally, but I know that the speed is off 1 mile faster than actual speed. I'm on a short trip with my trailer and 4wheeler mpg took a big hit I-State speed pulling it down to about 16.2 MPG not factoring in odometer /speedometer being off a mile. Not quite as bad as some here just lifting and larger tire. I didn't take that much of MPG loss with my 4.0 Jeeps pulling a trailer unless it was close to max load.
A strange thing is the odometer reading normally about dead on with GPS distance just the speed reads faster than actual speed.

MAYBE you are seeing the same thing I see - are you going by the analog gauge on the right, or the digital readout in the middle?
When I have my GPS and the cluster digital readout at exactly 55 - the analog dial ready 56 - even accounting for the parallax effect.
Always - analog on the right reads 1 mile over the cluster digital display.

Brand new JTR with hard tonneau. Only one tank of gas thru her and 3/4 of that was driving home from dealership a few states away. Speed on interstate range from 60 to 85 mph, mostly about 80. Based on miles driven and fill up my MPG was 16.97. Hope that improves a little after break-in.

Watching both digital most, and I use cruz control most of the time..... To keep it at speed limits or few under, at 70 the mpg dropped further down after about 60-80 miles I dropped speed back to about 66-67 mph to get back up to 16 mpg.

70+ is a MPG KILLER on these. If you want more mpg - you're not going to get it at 80 mph.
They do get better - typically 3,000-7,000 miles most see some improvement.
Of course winter months will drop it down in some locations.

Yeah I figured that but just wanted to get home, it was a long day.
Good to know 70 is the magic number for MPG drop off.
Thanks

Lol 13 city 16 to 18 hyway. But I'm on 35s with a 4.5 lift, and a bit of a lead foot lmao. Not concerned about milage though since it sits at work 20 days in a stretch and only driven 10 days when home.

I have many days like that......

My overland stock on AT wheels is getting 21-22 consistantly. The onboard reader is right on too. Every time ive calculated by hand its been dead on.

37”, 2.5” lift:
16-17MPG at 8800 miles

Same as all my previous Jeeps: I get to 1/4 tank, then start looking for a gas station!

Average mpg readout has been around 16 without resetting in a month. City driving and wheeling involved. I have not recalibrated for the larger 35" tires yet either, so it may be slightly better.

19. Has 4.10 rear. Stock everything. About 1400 miles on it so far. Might be a me problem. When my wife drives, we get around 24.

Just got back from a 1000 mile round trip to Pennsylvania. Almost all highway around 70+ mph. 18.3 MPG

Bone-stock Sport; averaging about 17-18 mpg.

 

[FLUndertaker]

14.5 with 4.10 and 37” Nitto. Mixed driving.

Sport S, stock drivetrain.
First 2000-mile trip through Montana & Wyoming at ~85 mph I averaged 17.4 mpg.
I added a Truxedo LoPro, and running about 75 the average has snuck up to 20.4 over the next 2000 miles. I haven't reset the average MPG reading since I started the Montana/Wyoming trip, and I'm a little over 4000 miles total.
