Question for Mojave Owners

[Biggy]

I average 18.5 mpg with 37" tires and stock gears. I would say 80 % of my driving is highway.

I get 12 average with both 35s and 37s.

Hey Guys,

I am considering a Gladiator. Prefer an EcoDiesel, but my local dealer has a 2023 Mojave 3.6 V6 automatic that is heavily discounted.

The window sticker says the V6 gets 17/22 MPG. Is this true?

What are you guys getting for MPG on a stock Mojave?

Thanks in advance.

If MPG is a big concern, a Jeep is not the best choice. The gas engine is a good choice for shorter trips. The Ecodiesel is a good choice if you do a lot of long distance driving. My last diesel was a 2006 Duramax. I do not want one of the newer diesels because of the emissions requirements.

I have a gas engine Overland that is mostly stock. I get up to 22mpg on highway trips. Daily driving is around 15mpg. I do a lot of remote start and sitting idle so that the cab is comfortable when I get in.

When I was stock I saw anywhere from 15-27. Highly variable depending on speed and hill climbs. Now, being heavy, I average 13-16. But if I dropped interstate speeds from 80 to a more reasonable 60, I bet it would be in the 18 range.

I've got a mostly stock Mojave. My last tank of gas, I got 17MPG from 80% city driving and 20% freeway driving at 70mph. My last roadtrip, I was averaging 21-22MPG on the freeways.

I guess it’s all in how you drive. I have steadily gotten 18-19 with in town driving work commute. Best hwy has been 22.9. Checked and verified the old fashioned way. I’ve got 41k miles. 3.6 Pentastar. Best truck I’ve ever owned.

Around home hilly area 18, 4MPG uphill and 99 mpg downhill, I travel Pa. To De. Highway heading to beach mileage averages 20, go pretty often ,stays the same, once I get out of PA. and hit the lowlands in De. Mileage gets much better and brings average up to 20. Towing a 4000 lb. Camper 12-13MPG.
Most Diesel owners are happy with the power but all seem to agree Maintainence costs are high, fuel is higher , fuel
pump hopefully is a past concern but lots get in high twenties in mpg. Plus the Mojave didn’t have that option….Jack

Edit: Stock Mojave tires and gears no lift, with winch (70lbs.), RSI cap (170 lbs.) a ARB fridge in bed (75 lbs.), skids and diff covers(perhaps (50 lbs.), Mopar performance steps(perhaps 75 lbs.) total of 440 lbs. added weight. Drive the brick slow don’t go much over 68, mileage drops pretty much after about 60 mph. I am happy with what get, and think it’s great actuallly.

Truth be said, there aren't any good MPG choices when it comes to body-on-frame 4X4 vehicles. Tacoma, Wrangler, Ranger, Bronco, Colorado, Canyon, Frontier, Gladiator are all in the same ballpark.

The gas engine is a good choice for shorter trips. The Ecodiesel is a good choice if you do a lot of long distance driving. My last diesel was a 2006 Duramax. I do not want one of the newer diesels because of the emissions requirements.

Good to know!

14.72 mpg over the life of the truck. 35s since 300 miles or so. The single best tank I have ever gotten was 19.9, once. I didn’t buy it for mpg. I’ve got 44K+ on the clock now.

 

[Jeep-of-Eli]

I‘d get anywhere from 17 to 18.5mpg on mostly empty bed, tonneau cover, 37” Recon Grappler, @31psi, and stock 4.10 gears.

I get 12 average with both 35s and 37s.

This is exactly my experience with my 2” lifted Mojave with 37’s and 5.38’s. In the truck’s defense, I’m pretty heavy on the throttle and the speeds on our interstate hover between 70-80. I noted that when I drop my speeds on rural highways my MPG’s jump 2-3.

Mine is a Rubicon, so I’m not sure if they are the same or not. I picked my Jeep up on Tuesday. 300 miles of inner state driving at 72 mph yielded 16 mpg. The last 80 miles of 2 lane roads yielded 20 mpg at 60 mph. Both according to the Jeeps calculations and both disappointing compared to what the window sticker says. It’s a 6 speed manual, so I’m sure that hurts the interstate mileage

Hey Guys,

I thought you said goodbye to us Jeep peasants a couple months ago? Already coming back?

I bought a 23 JTM in October. I immediately put 37's on it so I have no idea what MPG would have been stock. I do know the winter blend has dropped mine about 1mpg in the past month. Yes, Florida gets winter blend fuel.

I've had it up to 18.3 and down to 17 in my daily driving.

 

[Choatecav]

I've had my '21 Mojave for over 2 1/2 years and stay pretty consistently in the 17-18 range. Occasionally, I will have a 19 in there. Oh, and it is a 6 speed manual.
