    Also, the on board computer always indicates 2 mpg MORE than the actual calculated mileage.

    So the only 2.0 Jeep I've driven was a Rubicon. The computer told me it averaged 24.5 on the test drive, and that exceeds the 21-22 average I'm getting in my V6 Sahara (with 11,000 miles).

    Those are good numbers. My stock 2008 gets 18-20 only if I drive it like a grandma. These JL’s are frikkin’ awesome.

    My 2018 JLU Rubicon is all stock and I’m averaging 15 mpg , it was better in summer about 16MPG but I’m in Chicago all city driving basically the best average I had was 18 after driving to Michigan, so city traffic is definitely a factor

    18.3 mpg Sahara 2.0 stock. Not great, but traffic here in Fairfield County sucks. For comparison, my Audi Q7 v8 was rated at 14mpg City 21Hiway and in real life around here was 11.5mpg. So the 2.0L Wrangler in definitely an improvement in that area -apples to oranges comparison I know.

    Has anyone tried using octane booster with 87 octane fuel? Here 93 octane is $.70 more than 87. Have never used it?

    Don't do it. Pay for premium or just run the 87. I pay for 93. The amount of octane booster you'd need to take a tank from 87 to 91 would cost far more than just buying premium in the first place, and you'd have to do math every time you filled up and measure properly in order to ensure you were at the octane level you desired.

    For those of you who want a great octane booster check out boostane. I have been using it in my subaru sti for years and now using it in my new 2019 JLU. Engine only has 100 miles on it so once break in is done and the oil is changed to full synthetic I will report my mpg. Currently about 16mpg but I sit idle outside of work for about 15 minutes a day on cold mornings. Boostane I very safe for turbo engines and does not leave the nasty residue that others leave behind.

    Less than 650 miles on a 2019 JLUR 2.0L. So far I am averaging around 15.5 to 16. I expect it to go up some after breakin and when warmer weather gets here . This is about the same as what I got in the 2017 Sahara I traded in. Considering I am using Premium gas, the spark plugs require changing at 30,000 miles and it cost an extra $1000 upfront, looking back I probably should have passed on this option
