I haven't seen a thread on users experience with MPGs on the EcoDiesel, just assumptions before the truck got into peoples hands.

With a quick description of your vehicle (tires, gearing, etc), what MPGs are you achieving with your 3.0 Diesel.


I know a Jeep isn't a Prius, but a good/decent MPG with the added weight and larger tires will have a longer Mileage Range and more fun & less worries.

600 miles on my stock Overland mixed driving was 20mpg. Highway at 75mph looks to be 25mpg or maybe higher.

Keep in mind you’ll get a decent amount better fuel mileage after the truck has some miles on it. I’d assume you’ll see gains through the first 20k, maybe more.

Had my 3.0L diesel Sport S for a little over 2 weeks. Right at 20 mpg overall based on the computer. 515 miles mostly around my small town. Nothing really on the highway yet. It's been cold here (20-30s) during that time so that is having an effect I'm sure. I'm coming from a GMC Canyon V6 that would have been getting probably 16 mpg during this time. I'm hoping that warmer weather and more break in will make it even better. Another good thing here is diesel is only running .20-.30 cents more than regular gas.

I guess those who have the diesels have only driven a few miles and not gone out cruising.

Can't trust the computer. It's usually over quite a bit from everything I've seen

Winter blend is going to hurt your MPG right now too. My old ED took about 15k miles to break-in, but you could always tell the moment winter blend diesel made it in the tank. It’s good for another 1 or 2 MPG once summer gets here.

Isn’t the Mojave the 3.6 gas motor?

You might get more of those gas engine posts because you didn't put the word "diesel" anywhere in the title of the thread.

In fact.... the actual word "diesel" is not even in your first post either.... only a reference to ECOdiesel.

But I posted it in the 3.0 Diesel section of the forums...
