It is Possible to Get 25 mpg in a 5th Gen

You get 80mpg by rolling it downhill with engine off :crutch:
:roll:LOL

Offset by the fuel consumed getting it uphill. Just saying.

I have 225k miles on a 2017 and haven’t gotten close to 25 ever

Getting 19.85 MPG over 4829 miles on a stock 2021 ORP (calculation from actual gallons and actual mileage over 19 fill ups and mostly non-hwy driving). On board MPG tends to run about .5 over actual MPG.

Got this this morning driving like the old man that I am.

Instantaneous fuel mileage doesn't mean much, it's at the pump and the total miles traveled to get there that really matters and it's doubtful any 4Runner driven "normally" will get 25mpg over the course of 12-15 gallons used.

25mpg...I can only dream.

"19 PRO, 2.5 in up the front and 3.0 in the rear, 4.88's/285-70-17, full skids and dual batteries, with a drawer set...5780 LBS, full fluids but no cargo.
I haven't seen the far side of 16 mpg in more than a year. 15.5 is the current running average....as long as I don't exceed 70...

maybe. Remove all seats but drivers, remove spare tire, put on smaller tires, get a lithium ion battery, and then only put in gas a 1/4 to 1/2 tank at at a time to keep weight down, also make sure engine is pristine, new plugs, clean throttle body, highway speeds only.

then maybe?

Off a cliff

Impossible if you have a chip or crack in the windshield.
