Tire pressures.....air them up for better mpg. Makes a difference. I have heavy E load tires and I went from 40 psi to 50 psi and picked up nearly one full mpg. (+1 mpg).
This might sound crazy but it's 100% true.
I am getting the same gas mileage with my 2021 4Runner ORP with my 3 inch lift suspension, full skid, sliders and 285/70/17 Falken Wildpeaks..as I did when the truck was stock.
I am averaging about 300-320 miles before the low fuel warning light comes on and 18mpg. Same driving habits as before too however I do hit cruise control on the highways and set it anywhere between 65-72mph; never higher.

Careful 50 is out of range , I see a lot dudes over air and end up burning a bald strip right down the center of the tire. Since the increased PSI makes the contact patch tiny.
Warm temps + highway speed will bump that psi up another 5-8 psi. You could be running closer to 60psi. Which is what my 9800lbs 15 passenger van calls for. Which weighs 2x more then the 4R.
So an extra mile per gallon x 23 gallons = an extra 23 miles per tank.
Estimate 23 miles of gas to be worth about $3.
Say you fill up weekly 52 x $3 = $156
Prematurely burning out a $1200 set of tires to save $150 a year on gas doesn’t really seem like savings.
FAKE NEWS
lol jk jk that's good for you but still hard for me to believe because of my similar setup and resulting loss of MPG haha. 2015 trail w/KDSS. 3" lift, 285s, full sliders, skids, GOBI roof rack, other stuff (look in signature) and I get 14.5 average. And I drive like a grandpa.
Maybe bc of the roof rack and the affect it has on aerodynamics due to it? lol I SWEAR I'm getting the same mpg right now.
Has anyone tracked MPG data when in when off road?
Clearly there is a lot of factors that play into this data as mentioned in this thread. Ideally I am looking for a data set from those with heavy weighed down vehicles in rough terrain.
I am headed into the Maze next month and our route is longer than previous trips in the Maze and its the first time I am taking the 4R. I am guessing the mix between dirt in 2wd and sections of rough 4wd is going to put me around 10 gpm. The route puts us at 200mi between fuel stations.
Anyone input from those with actual trip data is appreciated.
