Mr.T

I'm new to the JK -- Curious what kind of ball park MPG or range off-road (18 gal tank) you are getting, and on what type of trail driving.

Mr.T

10 mpg and a 150 mile usable range would suit me fine. Planning a trip this spring, need >130 mile range, but that includes some pavement. I've been used to about 5 mpg with full size diesel PU, and less with another old PU (with a carburetor). Anyone else?

I feel like my JK doesn't use any gas when it's in 4-lo on the trails. I take it nice and slow when I am off road, but still... I think you'll be fine on a full tank of gas. If you're really worried just get a Jerry can.

I got between 6 - 8 mpg per day during a Jeep Jamboree in October.

Mr.T

Thanks, Ranjr. I hate carrying fuel containers, but I'm thinking about it.

Found this: http://www.rotopax.com/Rock-Slide.html that straps onto the spare tire and holds two Rotopax mounts. Anyone used this, or have an opinion?

I too average 7 mpg in 4lo with a fair amount medium rock crawling. More like 5 with heavier rock crawling.

Putting around Rausch Creek my dash gives me about a whopping 3mpg.

I only use 4Hi and 4lo when I have to on trails. I have done 150+ on a tank. I think 10 is a fair estimate.

Mr.T

On the 150+ mile trip, do you remember about about how much was 4lo?

Thanks again everybody, good info.

Maybe 35-40 miles. It was raining and late summer snow melt. Made for a crappy afternoon but challenging (fun) driving.

Stony Pass to Silverton, then Black Bear Pass to Telluride(?) Imogene Pass toward Ouray then Mineral Pass/Cinnamon Pass back to Lake City. We left Lake City about 730am and got back about 8pm with a lot of side trails and stops. It was a blast but long hard day - doubt I can get family to do it again.
