Finally got my Rubi! Now, I have questions.

Sounds about right. Your sport numbers were on the low end so your driving style is probably a big cause of it.

Be very easy on the gas pedal and youll get a little better MPG.

I have the same build (color and everything) minus the cold air intake, but same engine/transmission. I'm at 1300 miles after a month of use, I'd say it was roughly 600 miles highway (coming back from Tennessee), 60 miles off-road and the rest city.

I'm at 19 mpg, 87 Octane. I also have roof racks.

My 21 JLUR has also always had about 14MPG average. Half street half highway and I rarely drive in rush hour traffic. I never understood how other rubicon owners get numbers like 17-18 city and 21-22 highway. I’ve never seen above 18, maybe 19 on the highway. And it never changed with mileage and my odo is now at 8k. I didn’t even see any noticeable difference going from the stock 285/70r17s to 315/70r17. I still average around 14MPG and 18-19 on the highway abd I still see 8th gear all the time on the freeways.

Congratulations on the new ride, is that a 21 or a 22 and if so which gears did you get 4.10 or 4.88's as one will definitely lower you mpg.

Your Jeep should get better mileage after it breaks.

Jim

I feel that if it's broken it will get WORSE fuel economy.

My 2020 Challenger got 16mpg new, now almost 22mpg after about 3000-5000 miles.

HEY!! WHAT DO YOU MEAN BY 2 DOORS on a SMALLER TIRES??? You making fun of my 2 doors Rubi??? As far as I am concerned they are the SAME SIZE. Be nice or I am gonna set my fluffy dogs on you!

Oh and yes to the OP aka FknMeow - Congrats on the new Rubi!! Woot Woot!

No, I'm talking about the OP's previous 2 door Sport that he had before the new 4 door Rubicon.

Don't worry Ken, your JLR has very beefy tires! It's a JURASSIC BEAST!

Same as everyone else mostly. I get anywhere from 15-16 all city to 18-21 highway. I will say that driving style is a huge factor in MPG with this vehicle. I can get 2-3 MPG better if I drive 65ish vs 75ish on the highway. The thing is a block, high off the ground; aerodynamics are not its friend.

I was being a smart ass.

I've had a Rubicon Unlimited for 2 years with a 3.6 automatic and have never seen 18. Not once. I actually went down to 12.5 after putting on heavy 35 x 12.5 inch Nittos. After re-calibration I'm touching 16, so I'm pretty happy with that.

Didn't catch it, should have been breaks in, typing on a phone...

21 JLUR, Hard top, plastic bumper, 3.6 engine, 2.5 inch RK lift and K02 C rated 37s. I get almost 18mpg on the highway when I drive speed limit (65-70mph), closer to 17 if I push it 70-75. Drops to 15 or so when on the street. However, I'm never on the street long enough to see how low it would really drop to give a good assessment of the true street MPG.

 

[fknMeow]

To be fair, I will admit that I have people tell me things like "Dude, you're not in Iraq anymore. You don't need to drive like a maniac."...all the time.

Perhaps if I stopped driving it like a Humvee, I'd do a lot better. But then again, there's more to life than gas mileage, right?

Anyways, thanks for all the info, I appreciate it. I just wanted to make sure that the thing wasn't messed up or something

well the window sticker is full of shit....I never get close to what the window sticker said as this fat girl gets about 17 mpg on average city/hwy combined...2021 JLUR auto/ 2.0T with 35's

at $4.50 a gallon here in So Cal.....good times

-Both are/were 6spd Manual with the 3.6 pentastar. I was getting 17-18 city and 21-22 highway with the sport. This Rubi is 13-14 city, and highway is substantially lower too, but I don't have an exact number yet as Ive only had it for a couple of days. Is this normal?

You are driving a vehicle that is ˜15% heavier, has ˜20% lower gearing, ˜10% wider/bigger/heavier tires, and you are reporting 20-25% worse fuel economy.

Yes - I'd say that is about right.

I get 13-16 on my 2.0T/A8/37s/JLUR. Depending if I'm driving like a human being or a Tasmanian Devil.
