Re: POST 2014 V8 MPG's
5.7 4x4. I do an honest 85% city on my 11 mile each way commute, low speed, lots of stop lights but not any stop and go traffic. My worse tank per fuelly was 15.4 mpg.
I'm currently averaging 15.9 with about 4300 miles on the Jeep. The only freeway the jeep has seen so far is with a pop-up camper in tow.
Overall, the mileage is about what I expected. My best tank so far as 17.6, but that was 100% open road towing so actually not bad. I have yet to do a long drive without dragging something to see if I can get the 20 plus others report.
We get crap blended boutique gas here due to proximity to Chicago, in the EPA attainment zone... this is good for a 2 mpg hit based on my experience with my other vehicles.
