2.0 Turbo average MPGs

[RatherDashing]

After a two hour interstate drive, about 30min stop and go and ther rest at 70+, I averaged 27mpg. Very happy with that.

Filled up for first time at 300 miles with a tank of good Top Tier 93 octane from Costco

Computer says averaging 22-23 on this tank.

90% Stop and go city driving.

Best mileage seems to be around 50-60 mph where computer claims I am getting low 30s.

Taking it out of town next week, interested to see how I do with 500 miles or so of interstate driving in high 70s.

Using premium averaging around 70mph almost all highway from SLO to South Orange County. Everything stock.

The question is, have you guys removed the front bumper sections that connect to the flares? Those pieces may look bad, but prevent air flow leading into the wheel well. Should be the difference of at least 2-3mpg.

I've always thought there would be some MPG benefit from those (I kept mine). I'd love to see before and after figures!

My Rubicon didn't come with them and I get 23 MPG.
Granted it is a 2-door but still has 4:10 gears and is heavier than a 2-door sport.
Not convinced they save much MPG.

The biggest MPG difference is coming from the smaller tires I suspect since Sport>Sahara>Rubicon based on my anecdotal observations from reading the forum, but it would be interesting to see someone do a scientific test on the same road and conditions.

I get 17.2 Mpg stock rubicon 91
If I drive really conservative not letting go over 2 k rpms and slow starts and coast I can go up to 19.8 Almost 20
I live in Las Vegas most of my driving is city and off-road

Getting about 20mpg in my JLU sport. Only 450 miles on it though. Using 92 octane gas. I saw someone mentioned tires might make a difference... mine has the 18" sahara wheels and 33" tires.

They don’t have to save much if they help to keep the CAFE numbers lower. One mpg can make a big difference on Jeep’s best selling model. But to actually know rather than guess you’d have to compare the same Jeep with and without...in a controlled manner. Comparing two different vehicles won’t work.

You have my attention! My 2015 gets about 14mpg, and that's almost entirely city driving too lol.

I am still on first tank -- but getting under 17. is there a potential issue that I should have checked out?

Give it's few tanks. Let it break in some. After 5,000 miles mine started to get better.

I've been bumped down from 21mpg average to 18.1 mpg on the 37's Nitto M/T's. Honestly, thats amazeballs to me. I've been driving a Power Wagon on 37's for a long time now with way worse gas milage. LOLOL.

I'm still only two tanks into the new tires and lift as they went on last Saturday. So TBD if that holds up.

I still need to go to the deal and get my computer re-flashed for the 35s.......I was getting 26 mpgs prior to the lift and 35s on my Rubi
