Real World MPG with 5th Gen?

On the freeway at 80-85, no the estimates are out the window. Ha It gets maybe 22

I found, the best fuel economy is at 55 mph, like driving on country roads. Anything above that, and this big square box takes more and more gas to push through the air. When the best fuel economy around 23mpg I got on country roads, then drivng steady 85mph on open freeway in Wyoming I got 17.5mpg. That truck does not like to go fast.
 
13-15mpg.

Bumpers (medium light), skids, sliders, drawers, roof rack, 4.88 gears. Don’t go above 70mph (will be 3000rpm with my gears).
 
Everyone should know these 5th gens get underwhelming gas mileage. It states it on the window sticker and every website. There’s not a magic 25mpg 5th gen out there. Even going off a cliff. Where it would defy gravity and fall at 64 feet per second squared.
I think it’s logical to analyze typical mileage occasionally and identify some anomalies, or when modding, which usually involves weight.
There’s just not enough money wise to concern myself about a few mpg. I only drive an average of 8k per year. Close to work. I average -16 mpg, I can achieve 18-19 on the highway only. 33’s, lifted, full armor minus bumper.
At 16 mpg, $5/gal in the CCP, 8000 miles per year is $2500 yearly. If I averaged 20 mpg (I doubt there is a 4WD 5th gen that does) at $5/gal and 8k per year my gas bill would be $2000 yearly. That’s a 500 per year saving. That’s only about $40 per month.
 
^ I'll point out you can absolutely hypermile a stock 5th gen to 25mpg. I've done it on multiple 200+ mile jaunts.... going 70mph, not accelerating hard, and bleeding speed on uphill stretches. I routinely get 23+mpg on a flat 15 mile drive home across the county when the traffic is light and the signals are nice in the late evenings.

My average on 5,000 miles is 21mpg so far--city, highway, offroading and all. I seldom go above about 73mph in this truck. If I was one of those "lifted on 33's setting the cruise to 88mph" people, it would be much lower.

It's half true that if your finances are tight enough to worry about mpg, they were probably too tight to spend the $$ a 5th gen costs anyway. But there's nothing wrong with people trying to save noticeable money in a situation. We don't tend to deride people that go out of their way to save $7 on gas at Costco, we shouldn't deride people that are curious if their rig can do better on fuel economy itself.

Did you fall off a cliff? Lol. JK. I wasn’t deriding anyone. I was talking about myself and what I think about how mpg relates to a 5th gen. I don’t care about how others spend their money. Except when it comes to our government. Because that’s some of my money.

wait for the HybridRunner!
I'll wait

....I'll wait til like the 5th model year, because I ain't giving up the north-pole-and-back dependability of the 5th gen over some extra fuel economy until it proves itself hyper reliable through real world owners, lol

I feel the same way. I try my best to get the best mpg I can within reason. I kept roughly factory rake for aerodynamics. Kept the OEM front bumper skin and don't haul extra weight or unnecessary stuff bolted to a roof rack. I can afford the gas, but I just don't want to.

I did trade my 4R and daily drive a Tundra, so I can't really say I'm a big gas saver. Even with the Tundra I still do my best to get better mpg. Everyone has a margin where it's not worth the cost and that might just be relative to something else to spend the money on. I sometimes re-consider long camping trips on the basis of "Is it worth $500 in gas to tow my camper down to the ocean this weekend?" Can I afford it? Sure. Is it worth the cost? Maybe not for a short weekend. I might rather spend $500 on golf, movies with the kids, and a couple dinners or taking a fishing charter. If I could get 15mpg towing and cut that cost in half I would probably do it more often.
 
Well said.
I don’t give up time for MPGs but I do like to take the road less traveled.
Get out of the cities!

I was recently able to get over 22mpg on the highway in my stock '21 ORP. Just got 265 Falken Wildpeaks, a roof rack and will be getting a lift soon. I'll report back and see how much it drops.

Just installed my roof rack and had TRD Pro wheels and 265 Falken Wildpeaks installed as well. Today, I drove on the freeway for about 25 miles each way and on the way there, I was getting 18.5mpg and was really bummed. I couldn't believe how much I lost. On the way home, it seemed to be running much smoother. Not sure if it was more downhill or the freeway was better quality but I was able to get 20.8 which made me feel much better.
 
Just took my 2023 on P265 Wildpeaks to the mountains and back yesterday. About 200 miles, up to 10,000ft and back down with several mountain passes along the way. Idled 20+ minutes at the top taking photos. 21.5mpg for the round trip.
 
I've been tracking my MPG manually (every time I fill up) since I got my 4runner last december, and have averaged between 17.9 to 20 mpg, depending on how much my highway/city split is. I drove through one of the rare snowstorms in california earlier this year and was averaging around 16 mpg, which was the lowest it's been. At the highest, I got around 21 mpg, driving entirely on highway and cruising around 65mph.
 
I get 14.5 @ 80-82 and 17 @ 62. I've got Falken 285's and a supercharger so the mileage is about what I expected.
 
My average doing around town is anywhere between 12 to 14 mpg. Sucks. But, I knew it was going to be bad going into it. We had a 3rd gen 4Runner and didn't buy it for its economical gas mileage either.

Doing steady state highway I can get up to 20 mpg depending.

Biggest shocker was earlier this year when we drove from NorCal down to Death Valley and spent a week camping and wheeling, from Trona, thru Fish Canyon, Goler Wash, Mengel Pass, Furnace Creek, Panamint Springs We also hit Zabriske Point, Dantes Peak, Darwin Falls, the town of Darwin, and up to the Cerro Gordo Mines and up to Lone Pine. Just an idea of everywhere we went over a week. Drove a total of 1,271 miles and averaged 17.1 mpg, 35 mph for 36+ hours of driving time.
 
The computer has been remarkably accurate, within 0.2 MPG of the hand-calculated number and bang-on in about half of the few fill-ups I've had so far.

Lowest is 15.5 MPG after a half-day of some off-road shenanigans + traveling and from the destination. Highest is 17.9 MPG but all of my trips have a healthy helping of shorter stop-go trips.

Preliminary estimates have cruising on the highway at 18-20 MPG subject to speed and hills - 80 will probably kick that down closer to 17-18. Easy cruising without stops at around 45 mph can get the computer estimating 22-23 MPG.
