Yeah it could be driving habits. I baby mine, and I'm running stock steel wheels. Couldn't tell you what they weigh but I've been told 26lbs, if that's the case I'm only at 96lbs a corner.Between wheels & tires I'm at 117lbs per corner and I'm averaging 14 mpg.
I baby mine too. Most of my driving is short trips at 50 or below so I don't see 7th/8th gear much. Best tank so far was 15.1 and that was mostly a long trip doing around 60-65. I turned ASS back on for this tank for science. Don't think it's going to make much of a difference.
Around 55k with my local fuel prices. I'm just plugging numbers into Excel for fun and the price difference between regular and diesel will definitely change regionally. Gas owners may also opt to run plus or premium in response to pinging which would of course sway the cost side of things into the diesel's favor much sooner.
Absolutely my Sport S Jt diesel on 35's i get about 24.6 hand calculated my Rubicon Jt diesel on 37's i get about 21.8 hand calculated diesel is the way to go
The one thing i don't see in your calculations is resale value? As a dealer so far any diesel Jt on the market brings significantly more then the gasser i think mostly because theres way less on the market but the difference is enough to consider in gas vs diesel in my area
I'm in Colorado 5280 feet and on 37x20's Nitto TG's running 5.13 gears & I'm getting 13.8 mpg. I was getting 16.5 MPG but I recently added a smart cap EVO A which weighs 250 lbs. or so. I would double check that your tire size is calibrated properly and that the gearing is set right in the computer. I've seen those settings revert with the Tazer attached. Either that or you have more weight that I do. I plan to swap out the bumpers for steel one's add a winch, I'm adding power steps next week and side body armor. I may be down to the 10 MPG Mark before it's all done lol.I keep seeing mileage all over the place from individuals on this forum. There are several that don't understand why I don't care for my JT as a daily Driver, well, 1st of all, I love my JT, but with 5.13 gears, 5x 76lb tires, I am truly getting just 10 mpg's on the highway. Now to be fair, when I throw my 33's with the stock wheels on, I get 20mpg. When I had the stock baloney skin Desert Dueler's, I got 22 mpg, great right? When I have the 37's on, and I go about 45-ish, I'm up to 18. and I'm not complaining about my JT's mileage because I know how to get better mileage, but once again, I have a car for that. My truck has never done better off road since I put the 37's on and changed the gearing. I wouldn't change a thing. My main point is, It's all a trade off, and different parts of the country require different setups. I live in the Rockies, go to MOAB and Ouray every year since I've had it, 2 now, going on 3. I hate the mileage going to the play areas, but I love the truck when I'm at the play areas. Big Bear was the deciding factor for going to the 5.13 gears. Rock gardens were painful with 37's and stock 4.10 gearing. Now that its assembled, it is a blast. I don't mind it being amazing for trails, and horrible as a DD, it's the nature of the beast with a 40 mile round trip to work. Gas cost alot, and the tires were $450 ea. last time I checked, so while I am a true believer the JT is not the ideal DD, it is a hell of a truck if you build it the way you need, and I'm sure I'm on the off-road end of the spectrum. So what ever you use your JT for, make it the best and share with everyone here what you use it for, so we can all learn. I love seeing JT's everywhere, but my favorite place to see them is in the wild, on the trails, in the Jeep Meca country and I love seeing the smiles and the side panels plastered with BOH's. So until gas is completely out of hand, I will save the bulk of my miles for trails, and the not the pavement jungles of the city. I'm going to hit 4-5 more trails this year, and I really hope to see you and your JT on those trails, because thats where the smiles are the biggest and the JT was meant to shine.
I do have an RTT on as well that sticks up higher than the Soft top. But like I stated, Its all good. Even if I got 12-13 mpg's, (which might be the case once the RTT is off) so what, I'm not going to disassemble my JT for every use, when all I have to do is park it in my garage and drive my car. Right? Why run the miles up on an "Off Road JT" just so I can drive on pavement? Thanks for the help, but I'm happy, as I'm sure you are, for whatever it is you use yours for. See you on the trails.
Sadly my Costco doesn't carry diesel, a Costco about 20-25 minutes out of my way does though.Around 55k with my local fuel prices. I'm just plugging numbers into Excel for fun and the price difference between regular and diesel will definitely change regionally. Gas owners may also opt to run plus or premium in response to pinging which would of course sway the cost side of things into the diesel's favor much sooner.
Perfect answer. It's all good. If I could, I'd do the same, build a dedicated off-road vehicle and have a daily for the street. But my daily would probably be a stock JLU Sahara or something, because I like the 4 door convertible and doors-off aspect. But I'd have a built JT or JL for the trails, and a civil one for the street. I had to choose between having a daily-drivable jeep or no jeep so I picked having a capable enough, stock-ish, daily-drivable jeep. Ever since we sold our last one, I missed it.
My Diesel Rubi with 37's with stock gearing gets 23 on the road. The torque is a blast. I don't have any wheel spin. You forget what you pay for the Diesel options after driving once in the hills. I can drive 75 in 8th gear. it's a hoot to drive.
Not trolling with this -- I haven't done the math -- does the MPG improvement on the diesel offset the costs in the fuel?
