I do everyday going to work on the hwy, cruising speed at about 120km/h and have been for years.



What's wrong with your uconnect?
Starting day two, it will reset itself daily. It’ll make a popping sound then turn off for about 15 min. Then work again but the settings are partly reset. It’s driving me crazy and uconnect doesn’t seem to care about fixing it.

2018 JLUR
I have just over 1,000 miles on my manual JLUR. Averaging about 16.5-17 in the city and close to 22/23 on the highway.

22 mpg on the first tank measured by odometer / gas pump. Computer said 21.6. Standard city/suburban driving.

That's about 10% better than my '08 JK is now, but just barely better than it was when it was new-ish. Engine tolerances should open up in a few thousand miles, though, so it should go up from here.

22.7 mpg on the second tank. Computer said 23.1. I went 463 miles between fill-ups, which is fine by me. Some people want to pay the least for gas; I want to fill up the fewest times.

I have about 7800 miles on mine and average about 21 mpg, about an even mix of town and highway driving. I don't shift into 6th under 65 mph unless it's pancake flat or slightly downhill.

2004 Honda Accord coupe, V6 6-speed manual; ordered 2018 JL Sport 6MT with A/C and anti-spin. D status.
I ordered a 2 door Sport 6spd w/ softtop--the lightest, smallest tire 6 speed JL.

I'll see if I can crack a 30mpg average on a road trip.

Possibly one between SLC and M O A B

Nah, rowing through the gears is too fun to granny it like that! I was stoked when I finished the 300 miles breakin so that I could wind ‘er out a bit... gas mileage is for Priuses. :)

JL Rubicon Manual
Hello; mine is a JL Rubicon 2 dr manual, currently 2500 miles. Doing city 15 mpg, highway 19 mpg, combined 17mpg. Something like that. I was told that higher octane gas gives you better mpg; I am not sure about that. I am not willing to commit to pay for the more expensive gas, I don't see the need for that. What do you guys think? Also noticing some jerkiness on third gear: I am not sure what is that. Will be paying attention to that to see if it is more reproducible, granted that when you go to get it checked it doesn't do it.

Your numbers are very similar to mine. (Manual unlimited rubicon).
No jerkiness on mine. Can you describe better?

7,000 miles later... average moved to 18.9
Is yours a Rubicon manual? Because I see those numbers on other models but my Rubicon manual not even close.
