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

My on-board computer is very accurate.
Wanna know how accurate?
This is for 115k miles of mileage tracking. 395 fill-ups.
Average of computer readings (computer reset at every fill-up): 20.91mpg
Average of manually calculated readings: 20.98mpg
Total mileage/total gas: 20.97mpg

The worst differences between manually calculated and the on-board computer has been +1.57mpg and -1.46mpg

Out of 395 fill-ups, only 15 times has the difference between hand calculated and on-board computer has exceeded 1mpg.


Just wondering what kind of driving do you do? Are you on highway, long distance driving? What kind of tires? Any lift? I spent 60 miles a day on the highway and a little bit of city stop and go, I have never broke 17mpg.

No lift. Tires are in my sig. I posted a few weeks ago that I actually averaged slightly better MPGs with my Revo A/T tires than I am now with the street Michelins.
I fully admit that my circumstances allows for very favorable driving conditions.
I live at 4500ft.
For 10 years my daily commute was less than 7 miles r/t on residential streets.
The only other driving during the week is 20-30 miles to the stores which I usually do in the evenings when traffic is lighter.
All other driving is from Hwy road trips, a majority of that is through the Eastern Sierras on Hwy 395 where the speed limit is only 55-65 and I can routinely see 22-23mpg in both directions.
I do a lot of light off-road, about 200-300miles/yr but it’s not a significant hit on my MPGs.

I prefer the road less traveled.

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

I was rolling south from Mammoth Lakes into Mojave and was running on fumes. Long downhill and no traffic, so I turned my engine off and coasted (Subaru Brat). Saw a coyote out in the sun. He watched me, then chased the car, caught it and bit the door handle. I started and kicked it into gear.

As a biologist, I figured it was rabid!

Sorry for the diversion. Back to regular programming.
 
Don’t have a 4Runner but a taco with the same engine and with real gas I’ve done it several times. Usually am in the 22-23 range but if I’m out for a cruise it’s not hard to do.
 
I bought my 4Runner to haul shit and transport a ton of shit from point A to point B and in doing so I am averaging in the very low 14 MPGs pulling a 6x12 ft trailer loaded to 4000+ pounds with the 4Runner cargo capacity with another 500-1000 pounds.

YMMV, I'm happy with the above
 
Best I ever got was in my off road premium. 600 mile round trip from Rhode Island to Pennsylvania. Pretty much all highway, stayed at 70mph or below. I averaged 22.9. Street tires helped I'm sure. It was summertime, so the summer blend has helped as well.

I just averaged 26mpg the other day driving on 2-lane roads in that 45-60mph range. As soon as you get into stop and go traffic though, it drops dramatically. I try to take the road less traveled as much as possible, not necessarily to save gas, but just because I enjoy driving it. I'd say my real daily average is more like 18-19 range.
 
i see these sorts of numbers when holding between 45-55MPH, so smaller highway speeds in rural WI, totally flat. Bone stock.

This, plus eliminating or significantly reducing stop and go. Fuel mileage begins to drop dramatically over about 60 mph.
 
Just traveled last Sunday from Phila to Arlington Va round trip, went to pickup my daughter with her stuff and average 23.5 mpg,following speed limit max 70 mph.
 
My on-board computer is very accurate.
I haven't tracked it anywhere near as closely as you have, but the one in my 2011 has been within a couple tenths every time I have compared to hand calculated.

Never reads higher than about 13.8 unless I reset it and go down hill or have a big tailwind.
 
Sounds like fake news to me...Jk. I'll never see those numbers because I constantly switch between D, 4th and 3rd S mode gear going up and down hilly roads/highways lol. Coasting down hill with no cars in the way is how I see 25 mpg being possible.
