Best MPG?

[Campyman]

I'm an amsoil Guy. 30% is way high. 6% increase is about all you will see. I've only done the oil on mine

6% sounds right to me too. However a guy was here a couple months ago claiming sythetics would achieve a 30% improvement.

If you swap out everything you can see 1-2 MPG

Mine is usually 30-32. I do mostly around town driving of 15-35 mph. Occasionally go off road but that doesn't affect it because I don't run it hard. Mine is a 2018 and all stock.

Low RPM is the trick

 

[Michigan Mike]

Mine is a 2020 with the 538 gears mostly around town with some minor off road. I hand calculate at every fillup. Normal is around 25 but I have seen as high as 30.

I wish I could get 30, maybe slow cruse speeds. Auto or manual

 

[Michigan Mike]

It is a manual. Normal cruise is around 45 sometimes only 40 Mostley back roads and I'm retired so no hurry

 

[CJ2Rox]

Mine as well I don't get over 55 to much. Have air intake and a gutted Catalytic. I use mine as a daily driver since it get better MPH than my truck

 

[Michigan Mike]

Mine is box stock. NO chip yet. It will have one in the future.

 

[CJ2Rox]

Check out Gilomen. Far cheaper

I have a 2019 with 3.73 gearing and I'm averaging 29.5 mpg and I have 9000 miles on mine. It is tuned and has a DYI intercooler kit with the stock air intake. I run it around down and up mountains.

Street legal 2018 3.73 with stock bfg tires. Diesel Freak stage 2 with intake hold down. I check my mpg after every fill up and I'm getting 30-31 mpg consistently with normal driving.
