2014/2015 Grand Cherokee Diesel MPG

Hi- I am investigating replacing my 00 Cherokee with a new GC overland and have been trying to find real world MPG reports on the V6 Diesel/8 speed auto trans version. Would anyone with this drive train please comment?
Thanks in advance,
Jim

I have the RAM ecodiesel version. In my last trip between Houston and Dallas i averaged 28mpg at 80. A month ago we were driving in the Florida keys from key largo to key west and return (mostly between 45 and 55) we averaged 32mpg. I believe the Cherokee will do significantly better

My 2014 Summit Eco Diesel with only 2000 miles or so is averaging 25 mpg(not having reset the reading since I bought it). One short road trip(highway) calculated with pen and pencil was a little over 32. Plenty of get up and go for sure! Love it!

A great site to check the fuel mileage of any car available is Fuelly - Track and Compare your MPG
there is no need to join, there is a small tab that says browse vehicles. In any event just enter the make and model of the vehicle you are looking to check, and you will get real people's real world mileage. It is kind of like a social media site. Btw, just checked, and the diesel seems to average around 25 mpg

At the current cost of gas and diesel, it should be better than 30% compared to gas or it is a bad economic decision (that would be a gasser that gets 21 MPG)

RREAM- can you advise what your V6 gasser is getting? I have talked to several folks on the road, and they are reporting 18 to 20.
Thanks,

Jim

I have a 2014 Overland with a V6 and get 22 overall and another 1 or 2 on pure interstate at 70-75 mph. Got about 22K on it now.

I also have a 2014 V6 overland. Just drove 1800 miles of all interstate. The car computer showed 21 mpg. Actual calculation using mileage/gallons 19.3. Car Computer is almost always optimistic.

Just placed an order yesterday for an Overland diesel with the OffRoad Adv II package.

While 30 MPG highway is great that's only one reason to go with the diesel, the other is torque. Love the idea of 420 ft lbs both for towing and off roading. I understand Banks is now making an air intake/exhaust/programmer that will boost torque all the way to 700 ft lbs if you want to go that crazy.

Jeep definitely hit a home run with the GC.

Glenn- congrats on the order. what is your expected date of delivery? In time for Moab? i see from your sign-0n that you are an off roader. do you plan on replacing the TJ with the overland for offroading?
