MPG quesiton

Hello,

I have 2014 GC Overland 4x2 w/ 5.7L
Purchased on March, 2014.
I currently have about 9600 miles (I don't drive a lot).

I want to share info what other people get their MPG...
I'm getting 9.8 to 10.6 average..I don't think this is normal....or is it?

Re: MPG quesiton

Most people are getting more like 15-20 but I say a lot depends on your driving habits.
If you short trip a lot that hurts mpg. I've only seen it on diesels but I think it can happen on gassers too. If you drive a couple miles at a time your engine is much less efficient while its warming up.

Around town only, which are short stop/go trips, I get 11mpg from a 2015 5.7 4x4. Which is about what I was expecting. Haven't had it long enough to do a freeway trip yet.

Re: MPG quesiton

Hmmm. 19 MPG with about 80% interstate for my 2013, 2WD, 5.7L. Guessing it's your driving habits and a lot of city driving.

Re: MPG quesiton

Lets do something, go fill your tank. zero out your odometer A.

Go take a nice long 250 mile ride highway, do 65-70 mph with cruise. fill up the tank,calc your mileage, compare to trip A.

Bet you will be over 20 mpg easily.

Re: MPG quesiton

There are a bunch of threads that already detail MPG for multiple model years and all three engines.

And no, the fuel economy you're experiencing is not normal in the least. I get ~16 running around and 20-22 highway with my Hemi.

Re: MPG quesiton

Since you have less than 10k miles in about 1.5 year span. I will say your mpg is "normal". I'm guessing your trips are less than 10 mins in city driving.

Maybe idling more than others too.

I had 4 minute commute. Killed my calculated mpg, but a tank will last me 3 weeks.

2012 JGC 4x4 w/5.7 hemi with 40,500 miles and driven most of the time on the highway. Last 15 tanks I've used 89 octane and averaged 19.84 mpg. Really pleased with this and I only had 18.4 mpg when I was using 87 octane. Can't and won't complain.

Re: MPG quesiton

I get about 12 mpg in my 2012 Overland Summit 5.7 Hemi. But, I also drive a little more aggressive than most JGC probably owners do. I do probably half and half city/hwy.

Re: MPG quesiton

I have over 5,000 miles in a little over 3 months on a 2015 4X4 w/5.7L and average 16.5mpg with mostly 60 to 70% city driving.

Check out Fuelly - Track and Compare your MPG to see what other people are getting.

Re: MPG quesiton

Sounds about right to me, I have a 3.6 and do short trips 100% city driving and I average about 17.6/100km or I think that's like 13.3 mpg
