Mojave Gas Mileage

[arskemp]

Im getting 11.6 driving like a responsible adult. Bizarre.

I'm going to take the tire pressure suggestion and see if it helps me. I'm at 33-34 PSI cold and am getting the same as you (11.8) intentionally driving with a light foot 90% of the time. All city. That being said, I'm hoping this is also due to the engine not being broken in enough yet since I have about 900 miles on it at the moment.

I did hit 12.0 for the first time yesterday, woot! Felt like the birth of my first child. But I'm back at 11.8 today, lol.

I get low MPG as I do alot of in town driving. The issue is when you put an after market bumper on it, you remove the air dam. Its there for a reason! Now you really are a brick in the wind!

Mojaves (like the op has) and Rubicons don't have air dams. Actually, do any of the models still come with an air dam? Mojaves and Rubicons never did.

I’m between 14 and 16 with the factory Falkon M/Ts after a year. Barely any freeway driving. I have a Pedal controller set pretty aggressive though.

No way 11.6 average?? Stock Mojave? Have you checked that against the pump/odometer calculations? Something is definitely not functioning correctly and BTW you probably can go back to dealer for this.
On flat ground at 60mph whats the consumption?

Ill have to check flat ground at 60. I havent manually calculated, just going off the mpg display. I know, seems way too low.

Oh Ill mention I have 25K on mine already. I run AT tires at 37/38 cold per door sticker. Id have to drive like I as 17 to knock my millage down to 12.

Just have 600 miles on mine so far. Averaging 16.8 mpg. Mostly open road 55-60mph (rural) driving. Sold the stock Falkens and went with same size KO2's. Running 36 psi. Burning 87 octane E-10.

I am hoping for a slight increase during break-in and warmer weather. Honestly, I would be happy getting 18mpg. These are not designed to be fuel misers.

I have learned that mid-grade (89 octane) may result in better mpg numbers. Probably not worth the additional cost per gallon though.

Your Mohave is different than my Overland, but I didn’t start getting the EPA numbers till about 11k miles. It was like 4 mpg less before that. My Overland is pretty much stock except Rubicon take off suspension and 285s vs the stock 255s. They’re heavy though as they are E load. My mpg sucks in town, but it’s mainly my lead foot. I only get 16-17 mpg in mixed driving, but It’s pretty easy to get the EPA 22 mpg as long as I don’t go over 75 (non corrected). The computer is about 1 mpg optimistic, but when corrected for my tire size, it’s pretty much dead on.

I also get a few mpg less on winter gas…

^^ wait till we get E15 this summer.

E-15 is only an option that I won't be using. Most smaller stations here don't even have it. All other choices available up to 104 octane racing fuel. ?

Has anyone tried a tank of ethanol-free fuel yet?

the best i have gotten on my Rubi is 17.8 and that didn't happen until i got over 11k on the odometer. I use cruise in to work 65 and try too keep the rpms at or below 2k at that almost impossible. 17.xx is still better than my 04 taco
