You still might be in the engine break in period. I think the most efficient way to get the most out of your mpg is to quickly accelerate (not racing) to your desire speed and then cruise as much as you can without giving it much gas. So if you want to cruise you have to stay at the lower rpms. I'm driving 95% city with moderate traffic and getting around 17 to 18mpg. The few times I was on the highway I was getting easy 20 mpg.
I am in the same boat. I love my JT, but I do miss the low end torque.
Still running it like that. I did not recalibrate the speedo. It’s only a couple weeks old so getting the feel for it then maybe rehear and recalibrate. Thinking 4:88 would be a good gearing
So, question is... how’s it run and handle now? Before regearing? ;{
The Overland is marketed for “Overlanders” traveling long distance, mostly pavement, some off-road. But very MPG oriented. Rubicon is marketed for off-road Wheelers and Crawlers, who basically use pavement to get to their off-road locations. MPG ranks low on the off-road Wheeler’s priority list. 40’s reduce MPG. Towering lifts reduce MPG. Dana 60’s & 80’s reduce MPG. Beefy low torque differentials reduce MPG. Hellcat and Hemi engine swaps, reduce MPG. All of the above rank higher on a “Wheeler’s” priority list than MPG!
Regear is changing the size of the gears in the differential. A different gear ratio allows more torque to be applied to different gears, depending on what you want. More torque in low range gears gives you more jump off the line, more low range pulling, or climbing, power, etc... more torque in the upper range gears gives you more speed, in higher gears, at lower rpm... like overdrive, for highway cruising. The Rubicon’s factory gear ratio, 4:10, is FCA’s effort to provide the best all-round gear ratio for both scenarios. ;{
If you're used to V8 power, you're going to be a little disappointed in the JT. It does not have a ton of torque, and will definitely feel a bit sluggish.
Shameless post jumping, but I have the Mopar kit and 37s and stock 4.10s. Tazer for the size change, sorted. Power is plenty. Not thrilling, but more than adequate. Run the RPMs higher and it feels peppy... for a brick on 37s. Just have to have your perspective screwed on straight... it's a Jeep with a bed on big honking tires! It's great!
This is no doubt. It's EPA oriented. But I'll take it, so that it will continue to exist, and the beauty of the manual is I can defeat their meddling with a downshift!
Yeah, it's an RPM game, low as you can go and still go. I do more babying than standing on it, and I'm averaging close to 17 running 37s. I run 5 and 6 on flat and downhill, coast a fair bit to stops. Go fast slowly.
I can get near 18 with mixed city and 55 mph highway use. Mileage drops like a rock once you hit the open road. About 15 mpg at 70 and more like 12-13 at 80.
