With my 6MT 2DR Willys, I get about 8,5L/100km on the highway when the weather is good (27,6 MPG). Cruise set to 112 or about. This thing eats miles.
This September, after breaking my Sport S in for 5 months and 5k miles I did a 4,600 mile trip in two weeks from Colorado to Washington state, down the coast to San Francisco and home across Nevada. Stayed off interstate as much as possible preferring secondary, two-lane and dirt. I was shocked when I got home and saw my average mpg was 27.4. Stock Sport S with All-terrain tires, 3.6 and manual trans. significantly better than my previous Subaru ever got, with all the benefits of a Jeep. Happy as can be.OK, forgive me if this has been talked about many times before. I went on a four hour drive, all interstate, yesterday. I had the cruse control on probably 90% of the time. My Jeep, 2019 JLU Sport S with 2.0 turbo said 26.3 MPG. I don’t know how far off this is, but it sure looked good. Jeep is totally stock with HWY tread.
