i am your grandfather (72 yrs old) but nobody ever accused me of driving slow, just don't need to be the first one at the light ... click on my fuelly link and see all the data, manually entered .... dash mpg is mostly worthless, ours has been plus or minus 0.6 off .. no changes to JT, stock tires, 3.73 gears and automatic

Well thats a good point. Just how well does the dash mpg track calculated mpg?

Looks like your columns are one row off. Makes no sense otherwise.

I can squeeze 24 mpg out of mine in the right conditions but in real world driving I can't sustain that, and it averages back to about 18 mpg. Manual transmission Rubi, stock, Falken M/T 33s.

yep, copy and paste did not work as it should ... click on my fuelly link to see the whole story ... sorry

My manual JTM gets about 17.5 around town unless I baby it. On hwy its 21-22. This is at 200 feet so fairly thick air. I suspect a manual will do worse in town and better on hwy mpg wise.

I’m getting about the same as above, manual JTM. Recent tanks have been in the 19s with a mix of city and highway.

I drive basically a 50/50 split of city/highway weekly. I hand calculate my mileage with each tank. It's always consistent like clockwork.

I've had 4 of the P-star engines. In a Jeep they all would average 16-17 MPG.

I've had 2 of the EcoD engines. Those are 22 MPG average.

*This is with 33-35 inch tires.

How were the EcoD engines? Maintenance cost on them much different than the gassers?

Got the worst fuel mileage yet. 13.3.
It's just getting worse and worse.
Completely stock Mojave (well softopper, datinfab, decked). I drive short trips and mostly highway. I never idle the truck, I don't use a/c and abuse start/stop whenever I can. Easy on the skinny pedal.

 

[49Gramps]

Just got back from a 2260 mile round trip to Florida. Average mpg was 23.4. Mostly stock Overland, 1 1/2" up in the front, 3/4" rear, Artec skids, stock wheels & A/T tires.

Have noticed mine dropping a bit in the last few weeks as well with normal driving patterns.
I suspect the cause of this is the refineries are switching the gasoline formula over to the winter blend which doesn't deliver as good of mileage as the summer formula.

WTF are you hauling something? If you smell your exhaust do you think you're running rich? You may want to take it to the dealer if you aren't in manual all the time and just revving it as high as it can each gear. You're getting literally half (just a bit over) what you should be getting highway.

 

[Jeeperjamie]

I'm still getting 17.2 MPGs in my max tow with stock 4.10 gears on 37 12.5 17 Kanati trail Hogs. Just got 18 over the weekend on a day trip to and from the beach. If you only getting 13.3 you got some issues going on somewhere.
