Real world MPG, what are you getting in your Diesel?

[Free2roam]

Man, y'all are killing me with these posts. I'm beginning to wonder if mine is defective. LOL. I have only seen 22 mpg once. Averaging about 20 mpg with mixed driving.
Stock except for 35" BFG KM3's, and Tazer Mini to adjust tire size. Granted I only have a little over 1,000 miles on it, so hopefully it will improve as it breaks in.

Dunno. I've only got 1192 miles on mine.

I'm seeing 21.5-22.5ish on the regular with 37" and 4" lift. The diesel tends to shine on long hwy trips but I haven't been on one since I installed the lift and tires. My driving environment is mixed in a hilly area. I did do the necessary Tazer adjustments.

14.5 mpg towing this 6x12 that is 7.5' tall while driving 72mph. Its a brick wall for sure. I have Rubicon take off tires and 1.5" leveling kit on the front.
After 4000 miles I average around 22mpg with mostly highway/country road driving.

When y'all hand calculate at the end of a tank, is it 1-2 MPG lower than what the dash display shows?

That seems to be the case on the Ram trucks with the same powertrain. Dash is very optimistic.

Looks like there are only 10 people tracking their JT EcoD mileage in Fuelly. We need more! Although, the 22.8 average across those 10 Jeeps lines up really well with the JL and DT guys that have the same powertrain, and there are millions of combined miles on those now.

Guessing Fuelly is an app?

It's a website, but it does have an app I think.

It relies on odometer readings and amount of fuel entered to do hand calculations and statistics for you. It's nice because it takes all the guesswork out and shows real world numbers rather than inflated claims like we typically see all over the internet.

I have found over the years that Fuelly averages for a particular vehicle will often be more accurate than the EPA window sticker ratings.

I had used Fuelly on my JK but stopped using it when CarFax Car Car app included fuel efficiency tracker, same concept that it uses actual miles driven and actual gallons filled.

Can't imagine it being any different than my input on my phone. It's still inputting the info by hand. Miles driven ÷ gallons put in. It just keeps track for you over the long term.

Yesterday was my first long road trip since installing the 4” lift and 37’s. Cruise set at 70 mph from Florida to Indiana. Hand calculated was 23.5 mpgs. I’m pretty happy with this.
