I averaged 20.5mpg on a 300 mile trip yesterday (stock tires), mostly cruising on the freeway at 70-80. Surprisingly better than my 3.6 on 35s ever did.

It was in and out of 4 cylinder mode as I was driving on the highway.
That's not bad really and beats the claimed 17mpg on the highway. This Jeep would be perfect to be if it had a larger fuel tank. Say like a 30 gallon or so. I'm going to wait till long range america makes an aux fuel tank and add one.

I drove from PA to NC and drove her gently at the speed limit on the highways mostly in 4 cylinder mode and I actually did average at my best 18mpg for a good leg of the trip down!

It's all in the gentle peddle control and barely pushing it down to accelerate for good mpgs lol

You’ll get 20+ mpg on the highway especially with that cylinder deactivation. It’s in traffic that everything dips. Would definitely love a bigger tank.

If you get 20mpg on the highway why does jeep list it at 17?I would think they would definitely would be trying to spin the mpg as best they can. If it can achieve this number why not list it as say 15 city and 20 hw that sounds much better.

Those numbers aren’t at 80mph.

Who knows. I bet if you put the 392 on a dyno it also has 470RWHP. Underrating is the new black.

Oh now I wanna know how much wheel hp it's putting down. I guess with the awd it may read lower than the rwd woukd though. More drivetrain loss.

2019 JL Rubicon Just sold. On the prowl for a 392
This is where we ended when we pulled in the driveway. We hit heavy traffic at times as well so there was idle time in the overall trip as well.

Thats amazing. My R/T durango with the regular hemi is at best 21 on the highway with a very light foot

Hey Mike, this is not in relation to MPG's, but where did you get the Carbon Fiber Gauge surrounds?
Ahh must be the stickers that cut into my mpg.

Took them off my ‘18. I think I got them on AliExpress but you can find the same thing on Amazon. Can be a pain to find the matching weave direction and color if that bothers you.
