What kind of gas mileage are you experiencing on your 2011 Grand Cherokee? (V8 engines only please)

On non-mountainous highway at 65mph or under I'm seeing 20-22mpg and got a bit better than that a couple times where I was forced to drive slower and had some tail wind. I've only had one cross country trip (IL to GA and back) and overall, with stops and a couple very short excursions, it was just under 20mpg (averaged to and from). This was with four people and gear but no trailer. If I get pass-happy the mpg drops down to 17-18mpg highway driving.

The V8 drinks a lot in city, stop and go type driving. On the highway it does great, as others have posted. It is also much louder than the V6 at normal cruising speeds. The V6 gets annoying if you are climbing a hill and it is at higher rpms because of it.

19.1 @ 80mph with light traffic and light hills (calculated over 120 miles using EVIC)

Around town, heavy foot, on/off 65mph speed limit freeway, tons of idling, stop and go, warming vehicle up......12.5mpg. If I change my habbits and drive like a normal person and limit idling, 16mpg can be achieved.

We averaged 17 on EVIC on a trip to VT, car loaded with dogs, luggage, etc....I average 12-13 around the city.

Similar to what I saw, fully loaded, 2 adults, 1 child (you know how much stuff comes with them less than 1yr old), 3 golden retrieves, roof rack with cargo bag, 75mph, 16.5mpg is all she would do.

From my observations the EVIC is a little "too generous" with the mileage estimations :)
From my observations, this is the closest mpg calc from a vehicle I have seen. Couple times I checked it it was spot on (plus/minus .5mpg). You must remember to reset as soon as you fill up, you have to take into account idling and accelerating. You can't reset once you are moving and then hand calculate when you are done and expect the same results!

I have just under 3000-miles and i've had my Jeep for almost 12 weeks.

The majority of my driving is done in-and-around town. Most of which is my daily commute; 13-miles each way (130-miles/week) averaging 20mph and 45min of travel time, i.e. lots of idling. And, we run errands and visit the parents over the weekend; nothing crazy. Only three "long" trips (each about 150-miles one way). I remote start each morning for a few minutes and recently its been in the teens/low 20's in the morning. I live in the mid-atlantic so its coastal and flat here.

My EVIC is always between 14.9mpg and 15.6mpg at every fill-up/reset. During my "long" trips I averaged around 20.

I haven't seen a gain since the K&N addition, but I haven't seen a drop either and its been colder.

The spring & summer will def bring higher numbers because I won't be remote starting.

Overall, I am happy with the MPG - but, lets be honest, MPGs are not the reason I, or any of us, drive a Jeep. If you are finding yourself stressed about your MPGs and your wallet is screaming at the pump... well, don't buy V8 w/ permanent 4WD.

And, following similar logic, don't drop $40k+ vehicle if you are worrying about filling it up with gas - maybe you are out of your comfortable price range. It's like those people who buy McMansions and can't buy furniture to put in the rooms - whats the point?

Am I out of line to pose the following? If gas mileage is important, then why purchase a Hemi? I have owned Hemi's in the past. I know tool around in a 2011 Overland Hemi. I was fully aware of the mileage the beast is capable of. I did not purchase the engine with mileage in mind. Performance was important.

Well I drive 4.5 miles to work so 9 miles commute. I havent driven the car on long trips just yet so no highway as of yet (havent had a change to go skiing).

Anyway, EVIC say that my mpg is 11.5 but I am a real heavy footer.

I agree with mhassler so I dont worry too much about mpg but I do keep an eye on it since it could identify possible problems that are growing with the car.

I would like to know how many of the 20 plus MPGs are 4x4 models? (I'm sure there are a few) Also as everyone knows speed is a big factor as is using the cruise control. I've had a few local highway trips of a little over 19 (that’s with winter blend fuel and very cold weather). Also I have only used 87 octane Phillips 66 as this is the best fuel mileage fuel I got from previous vehicles owned. I think that I can get 20 or more once my vehicle is broke in and the highway trip is longer than my recent 50-60 mile highway trips.

Overall this is a good poll….great idea….and a good job setting it up.

Is there a reason you are neutering the performance of the Hemi with sub standard fuel? Recommended octane is 89, 87 is only in a pinch and the motor will pull out timing (i.e. power) when 87 is being used.

I average 10-11 mpg city. Well technically we don't live in a "city" being on Long Island but I suppose theres lights, and stop and go etc.. I would like to see it closer to the rated 13mpg city or at least know the conditions they had to achieve 13mpg for "city" driving but I know that won't happen. Using cruise control achieves better results obviously speaking however highway MPG is a completely different ball game. I haven't gone anywhere far by any means yet but I can keep it near 19-20 when I reset after a fuel up and jump on the highway for half an hour.

I agree with the last post. I use Shell here in NJ with no issues
In a vehicle that is suppose to have 91 octane. Car runs great
So I plan to do the same with the GC.
