Well mine says I get about 27mpg but I always check it myself to know for sure. I actually get about 21 mpg’s everyday time. I don’t know why this thing reads so far off. My other cars normally only ready about 1 mpg off. Mines a 2018 1.4 by the way.

I started with 30 highway, 25 city and avg of 27
Now my average is 18.8
It seems like with every update I lose miles 😭

Those are impressive numbers Larry. I can't get anywhere near that. 27-ish on the highway is the best I can do, and that's if I really behave myself. Best average in mixed driving is 25-ish, trending more toward 22-ih in the cold temperatures.

It gets better for me and worse for you guys.

I only ever reset odometer 1 and yesterday when sitting outside the shops waiting for the wife I noticed that odometer 2 had some figures. Now I wish I taken a picture as the figures from just over 11,000 miles showed an average (UK)mpg of 48.9.

Why is it possible for my fuel consumption to be as low in comparison to your car in the USA?

  • Is there a difference in the grade of the diesel?
  • Are your engines only petrol driven?
  • Could your engine be enhanced a little?
  • Has anyone chipped or remapped their car?
  • Does very cold weather cause a rise in consumption inversely does a warm climate cause a drop in fuel consumption.
I am sure there will be many varied answers but what better place to explore them than on this awesome forum with so many knowledgeable Jeep owners.

That's certainly wonderful fuel economy, and I wish we COULD get a diesel here in the States, but it is not available. We have 2.4L Tigershark gas, and 1.4 (now 1.3) turbo charged gas, and that's it.

I know for me I was averaging, if I drove conservatively (which I don't always do), in the high 24s. It seems to like to indicate 24.7. Now that it is colder, I'm in the low to mid 22s.

Using the 4wd with it's extra drag drops the mileage some too.

I've always been one to keep a log book. Don't know why, just always did. I can tell you every gallon of gas I've ever put in any of my vehicles. Thus far, my paper calculations are consistently lower by 1 mpg or so compared to the dashboard display. I feel like this is a more "real" number, particularly as time goes by, and I can average all the entries on a page, and average several pages together.

Winter gas formulation does not help with gas mileage. I notice a 3 mpg drop in late fall when the weather cools and the gas formula changes. Winter blend gasoline contains 1.7% less energy (according to EPA) which in turn causes lower mpg. The winter blend needs to evaporate faster so the engine will run better in the colder temperatures. It is just the opposite in summer, the gasoline needs to evaporate at a slower rate.

☝ I forgot about that.

Hello all, I'm curious to see what your average gas mileage is. I have had my 2019 Renegade for almost 2 weeks and I'm at around 250 miles (I live 5 minutes from my job) and I'm getting 17.1 which is mostly short distances with a decent drive both ways on weekends. I understand the average car's "break in" period, but does this seem normal? It's EPA is 23 city and 26 combined which is where I hope to be. I guess my question is if it's normal to be almost 10 mpg off on a new car's fuel economy rating. I have had a Subaru Crosstrek and a Chevy Sonic and drove under the same conditions, short distances and mostly city and averaged around 24 mpg. Will I gradually see my average climb over time? Just seems very low to me even if it has only been a few weeks
In my country we measure fuel consumption as lirtes/100km. I have had my 2018 Trailhawk for 18 months and the average is 10.4l/100km or 22.6mpg which I consider very high.

Everyone here seems to have a 1.4 or a normal renegade.

does anyone have a trailhawk? my 2018 trailhawk does 16-18 mpg and it does not move from there. my commute to work is about 20 miles each way. they only difference is that I changed the tires.

Our TH with about 14500 miles and with all the stuff we done to it plus testing out Madness go pedal we are getting about 19/21 in the city and on a 2 hour highway ride we got up 31 MPG.

Are you clearing the trip odometer / mileage calculator with each fill-up, or is that an average for your whole time of ownership?

With two trip odos, I clear A with each fill-up, and I let B roll for more of a lifetime average.

I think the official stated fuel consumption on Renegade's is crazy optimistic. I've had both a 1.4 petrol and 1.6 diesel and here in the UK, the real MPG for town driving / slow traffic is the urban figure minus about seven. For motorway driving, it's about 5 below the combined figure if you're doing 50-60mph.

DK search for a few of my posts regarding fuel consumption. In the post is a "chip" for £125 and it's a UK company.

I won't try to convince you as the evidence speaks for itself. I must be one of the lucky few with exceptional fuel economy. I drive the Renegade Longitude 2.0 4x4.

Also, we guys from the UK need to remember that a UK gallon is different from a USA Gallon. its the equivalent of 1.2 UK gallon to 1 USA gallon or 1/5th therefore if you get 40mpg they get 32mpg. ;)
