I get anywhere from 28 to 30ish MPG on the highway in my JL. Entirely stock Unlimited Sport S with the 3.6L eTorque and automatic transmission. I am so impressed with the milage! I do go the limit on the highway (which is either 100km to 110km).Translation: 33 mpg and about 620 miles per tank!
That’s pretty impressive! Can you share a little about your driving style and speeds, etc? Lots of highway?
