I'm blown away by the MPG on the 2014 3.6L
 
I felt guilty for a long time even owning an SUV. My old GC would get 21 MPG on the highway on a good day. It always seemed to average 19 MPG. Which was not bad. 4.0L Select Trac II (I think it was, 2WD, Part Time 4WD, Full Time 4WD and 4 Lo).

I put off buying an SUV for a long time because I was looking for something the same size, with the same towing capability with a step up on MPG.

I kept looking at the Toyota Highlander Hybrid. But it was so damn ugly/plain and pretty damn expensive.

I hated the prior generation GC's (round lights). Ugly. Terrible MPG, friend had one and then dumped it.

The new Jeep was growing on me. But so much bigger than I really needed/wanted. The old one was the perfect size. Why waste gas on a larger SUV I don't need.

When the new 8 Speed Transmission was announced, that was enough for me to pull the trigger. I was temped by the diesel too.

The diesel was too expensive and not that many more MPG's for the cost. The added Urine and poor initial reviews always turned me away. Not to mention Diesel is usually $0.50 more a gallon. It just didn't make economic sense.

I reluctantly got the 3.6L.

I'm blown away.

I did a 120 mile strip and averaged 28 MPG !!!

I'm still on that same trip and added another 80 miles of City Driving (suburbs) and I'm still averaging 24.5 MPG. And that is with it out of ECO Mode.

I'm just blown away that I can have this larger, heavier SUV. And have the optional Sport mode and Paddle shifters and get pretty damn good MPG when I behave behind the wheel.

Someone in another thread said they averaged 15 MPG. You have a lead foot or something is broken.

By the way I do have a few extra pounds in the tires.

The truck isn't even broken in yet.

I've yet to pull my 4500LB boat in sand, that will be the final test. My old Jeep pulled it out easy. Many other SUV's (neighbors in the same setup with lighter boats failed with their SUV's). Possibly this weekend.

The digital readout can be VERY optimistic BTW. I took a trip with my 14 Hemi last weekend and got 22.5 on the freeway in ECO mode. Total trip was roughly 600 miles. I truly hope you are getting the 28 mpg because that would be pretty damn sweet.

Last weekend on a 688mi trip home from N.C. to NYC the EVIC said I was getting 28MPG! 27.5 door to door, 99% HIWY. Even if the EVIC is off by a few I still think that is way good. BTW I let the car do most of the driving, ACC set all the way home. She did a stand up job, always the right gear it seemed. Better than I could have done.

My experience with Chrysler EVICs has always been around 95-100% accurate.

Thats cool, others on here have done the math and confirm your experience. I still have not had her home long enough to see what my every day #'s will be. I can say the big girl gets greedy on the city streets. BTW I love my jeep ,thank you great job!

Holy crap Marlon_JB2, where've you been? Nice to have you back.

Back on topic...is this a 4WD or 2WD Grand Cherokee?

60 psi tires, tailwind, downhill, both ways. LOL!

Seriously, that's awesome economy. Certainly way better than the average reported here.

I'd love to see your hand calculated mileage. Top off, reset tripometer, drive, refill to same topoff. Miles / Refill Gallons.

Glad your loving your new ride!

Thank you,

she is all I expected and more. Truth be told I was getting a bit worried hanging around the garage, with 2,000 plus miles my fears have been squashed. I made it from Asheville N.C. to the mason Dixon line (P.A.) on 3/4 tank of gas. Evic said I still had 200 plus miles to empty. I filled up because I was worried I would hit a traffic jam and start eating fuel like a sumo wrestler. I tried to take pics of the EVIc while I was driving, they all came out blurry. I'll go out to the car and snap a photo as soon as my daughter picks up my grandson. I love being a pop-pop!

Me too, VW's have been very accurate for years.

Over long distances, it's not that hard to be accurate.

Oh my 28 MPG was with A/C running and running Cruise Control (non Adaptive).

But I don't drive 75 MPH. That is with it set 65 MPH (MAX) and often below that. That can make a huge difference too. Change it to 70 MPH and you'll probably drop to 25 MPG.

My calculated averages are coming in 21-22 mpg per full tank (70% highway work commutes). EVIC running around 1 mpg more optimist for me (showing 23.x)

You got that with the 5.7L Hemi ???

Did you get the high ratio differential? 3.09?

What pressure do you run your tires? That can make a significant difference too.

By the way, my wifes VW CC can get over 40 mpg on the highway 2.0T with a stick (with Hyper Miling some, nothing crazy, Neutral in long hills and looking ahead). When dealer changed the oil it dropped 5 MPG. I researched a ton and found a lighter weight oil that meets all the strict specs. VERY expensive. $9/QT. But I immediately got the 40 MPG back. I've done oil tests etc. to verify everything is in ship shape. I believe the car was shipped with the oil I now put in it (or similar). I ended up with Castrol LL03 Professional 5W30 (only VW dealers sell it). Dealer put in 10W40 (which is within spec and was a very good oil).

I plan to do the same on the Jeep.
