Stock Rubicon JT MPG--What are you getting?

[Blu542]

Stock, just turned over 5000 miles today, 20.3 mpg with 80% hwy. I definitely saw a gradual increase starting around 3500 miles.

37s, stock gears. 17-18 around my area, 20 on the hwy.

Great inputs everyone -- thank you!

Stock Sport S at 1200mi

Half city half highway. Currently at 20mpg

It will get better as I adjust the driving and avoid passing semi-trucks going up hills

At 4k mileage gets better.

undercarriage parts start rusting and falling off so you drop significant weight.

A Harley guy would know, lol. (I have one, too).

I have about 3800 miles on my stock Rubicon with 33s. I filled up today and got 19.2 (city, highway and off-roading/4WD). I drove a windy, hilly state highway home for maybe 50 miles and got 20.2 on that short trip.

I have 2,100 miles on my Rubi Gladiator with 35” tires, auto trans, with no lift or added weight. The computer was accurately recalibrated for the taller tires (as checked against the Waze GPS).

Lately, I get about 16 mpg when cruising at around 78 mpg.

I got 18 mpg on a recent trip cruising for 220 miles at 68-70 mph.

Unsurprisingly, I just got 17 mpg in a 260-mile trip where my speed ranged mostly from 55 - 80 mph. On that trip, I was loaded down with about 200-lbs of children, and a bed and storage rack full of camping and hunting gear.

I got 23 mpg when cruising at 60 mph on relatively-flat terrain for about 20 miles with no load to speak of and no traffic slow-downs.

BTW, something is incorrect in the numbers pictured below.

If I really was going 267.2 miles in 2 hrs 25 min, I would have been averaging 114 mph. And I wasn’t. It was right at 17.0 mpg until I turned into local traffic.

Wow. What types of speeds are you doing on the hwy?

I set it to 63 and relax

Just above 19 mpg with 12,000 miles on it. Running stock Falken mud tires and no lift. Tire Pressure around 33 cold. Mostly freeway around Denver at 75 or so. Drops to 14-15 over the Ike and loaded for a week.

I didn't see any kind of increase after 4k miles lol. I've got about 5800 miles on mine and average 14.7 mpg. I've taken 2 road trips, one from TX to CO, and another shorter trip of about 300 miles, all highway. I got 15.5 both trips. And the trip to CO I had camping equipment and a RTT. On the 300 mile trip, I had nothing but a couple of duffle bags and nothing in the bed. I do have 35's but even when I had the stock 33's, mine still only got about 15 mpg. I don't understand how these trucks can vary so much in mileage from a highway trip getting 15.5 mpg, to others getting 19-20 mpg. Everytime mine goes up a slight hill on the highway, my mpg drops to about 10 or less, then when the hwy levels out, and it shifts back into 8th gear, it goes back up to maybe 17 or 18 mpg. So the constant up and down hills on the hwy's knocks my average down to about 15. And Texas is relatively flat.

I definitely saw an increase in mpg after about 3000 miles. As my JTR sits right now my odometer is showing an average of 17.8 mpg with 12,128 miles. The last couple days have involved running all over the Denver area during rush hours so mostly sub 20 mph with our traffic and lots of stop and go. Some bursts up to 55 or 65 but mostly a traffic jam.

In October I went for a 2 week solo Elk/deer/pronghorn hunting trip and hauled my trailer with all my camp crap (not a light weight camp either). Driving up I-70 I was running about 65 mph until the last 10 miles which became a parking lot moving at about 5-10 mph. This held steady to the Eisenhower tunnel (11,100 feet and 60 miles from Denver at 5280 feet). Right at the tunnel I was at 14.7 mpg which held at about that mpg all through the dirt roads to my camp in the Flat Tops and through 200 plus miles in 4low.

I came home for a couple days in the middle of that trip but left my camp and trailer there. When I headed back I was basically empty and got 16.7 mpg over the pass.
