I don’t think 500 is realistic - when the regen kicks in and the exhaust fuel injector starts spraying your mpg drops by a few. The best I’ve done on a tank is about 400 which is still pretty good.The torque of the ecodiesel already has me interested in trading my 2.0.
27 mpg in a JLUR is fantastic. That’s almost 500 miles range.
But my motor is still breaking in (about 1,600 on it at the time of 27.3MPG) I hear these eco diesel will pick up another 2-3 mpg highway after they are fully broken in. (8-10k)
When I got 27.3 it was driving from Palm Springs to Redondo Beach basically so it was a very flat drive with elevation close to sea level. If you start going up grades it will go down also.
That being said I literally can’t get this thing to get less than a 22.3 MPG average even around town no highway, and I have a heavy foot. So it’s definitely super good for a JLU
I went with the diesel really though because I want to still be getting over 20MPG with the 40” tires.
Jeep going to shop this weekend to get its makeover so next year I should be able to tell you what kind of mileage I can get with the 40’s in a similar scenario.
I bet if I was actually driving 65 I would’ve achieved 30+ MPG in that drive from Palm Springs to the coast. It was just a really long drive so I was hauling ass though.
