WK2 2013 Grand Cherokee What is your AVG MPG?

I am curious what the WK2 2013 Grand Cherokee and around that date are getting for average miles per gallon...

When you respond please let me know:
  • What is your avg mpg?
  • 4 Wheel Drive or other?
  • Year
  • Do you have a V6 or V8 Hemi's?
  • What type of terrain are you driving (hills, flats)?
  • What is your average road types (city/highway if highway is it a lot of traffic or none)?
  • What is the climate like?
  • What gas octane are you fueling up with?

I know I saw another thread on this but it was for WK and there is a weight difference I am sure between WK and WK2 plus different technology between both. I did not find anything for WK2 giving all this type of info as well and apologize if posting this is considered duplicating.

Why do I ask... I am trying to figure out if I should be getting better average mpg then I am. If others are getting better then I want to work on what I maybe doing wrong with the V8...or if maybe I should think about changing it for a V6. We were told upon purchase it being a differential engine it can be just as good as a V6 because it will often run as a V4.

So my answers.
  • My AVG MPG has been between 16-17
  • 4 wheel drive
  • 2013
  • Driving a V8 Hemi.
  • I hit a mixture of hills and flats.
  • I do a mixture of city and highway, mainly city and when I hit the highway there is no traffic and it is for short trips.
  • The climate here is at the moment 30's-65's
  • I am filling up with 87 but plan to do test runs with 89 after a couple more weeks and see if the cost of the higher octane fuel gives me a difference that is worth it.

THANK YOU for your help ahead of time.

There are several threads for WK2 here that discuss the topic, if you want to add that to your research. You may get a better feel, but most eventually turn into peeing contests. There is a wide range of production variances as well as driving styles and V8 mpgs between 14 and 20 are not uncommon. You are right in the normal range. Some get 12 with a lot of towing mixed in. Just saying.

The mpg benefit of MDS (v4) is only apparent on long open highway drives. The V6s get at least 2 mpg better in everyday driving mixes, but there are a lot of variables. All the typical mpg driving techniques will work a bit, max tire air pressure, don't idle long, don't exceed 65 mph, drive as if you have no brakes (anticipate and smooth throttle).

Oh, if you happen to get a vehicle on the low end of the mpg curve, what are you going to do about it? There doesn't seem to be anything that can be done about it beside trading for another an hoping for the best. So don't worry, be happy, enjoy the miles of smiles.

-Average MPG goes in between about 18 and 22 depending on my mood.
-I work in downtown Seattle and live in the burbs, so its mostly highway/city driving but it is hilly in the city. Plus, my in-laws have a cabin up in the mountains, so we like to get up there at least once a month.
-Climate: warm (70s-90s) and sunny in the summer, cool (40s-60s) and rainy in the fall and spring, cold(30s-50s) and rainy with occasional snow in the winter.
-I use regular gas. 87 octane

2013 Summit, 5.7 litre hemi. In cold weather I'm lucky to break 11mpg! Summer time 12 - 14 mpg city. Cannot, absolutely cannot get past 17.9 mpg freeway only. What the heck's the matter with this big pig? I'm not in "race" gear! Any answers will be helpful since the dealer is brain dead on this issue.

I had a 2013 Ram 1500 Hemi and those are about the mpg numbers that I was getting.

Your Hemi has MDS which shuts down 4 cylinders when cruising and the engine is not heavily loaded. That's been standard since MY11 and continues into MY16.
