I did some experiments with on-board mpg computer. This is 2012 SR5 with no lift, factory roof rack with factory cross bars and original Dueler tires. With 35k miles under the hood it is pretty much like it came from Toyota factory.
1. Going 75-80mph on flat highway (traffic flow was really good) I reset the mpg computer. After about 40 miles of almost constant speed the computer showed 18mpg.
2. Going downhill on San Mateo Bridge about 60mph I reset the mpg computer - few seconds later the display showed 38mpg. Yes, it did not last long and as soon as downhill ride ended the numbers started to dip down.
hwell:
3. Going on flat part of San Mateo Bridge at 55-60mph I reset the computer again. Before the end of the bridge the display stabilized at 26mpg.
4. When I get to I5 and traffic loosened up a bit the mpg start dropping fast. Between 65 and 70mph it dipped to 22mpg.
All that driving was with very smooth accelerating and minimum breaking (I kept distance in front of me so I could coast to slow down when needed).
So here is my conclusion: In order to keep economic mpg 4Runner likes to drive between big rigs at posted speed 55mph. At common highway speed between 65 and 70 you may expect the EPA's published mpg. Anything faster and 4Runner gets very thirsty.

I've since traded in for a new trail. But for the last one I had 265/70R17 Duratracs in passenger rating. I had a rola rack on factory crossbars and 2 KC daylighters attached to those. I tried to drive very conservatively but was never able to get higher than 16 average. That is with about 50/50 hwy/city. I calculated by taking mileage driven divided by gallons filled up.

I just got back from a trip from the bay area up to lake tahoe. I got 19 mpg average going up and ended up getting an overall average on the tank of 20 mpg when I got back. I had aired up my tires to 40 psi prior to the trip. This trip was about 400 miles round trip including driving back and forth to the ski resorts so I'm pretty happy considering the mileage I got on the way up. I wasn't trying to conserve fuel, I was driving at 75-80 mph where I could, obviously slower on the 2 lane mountain roads.
Previously my best was 20-21 mpg on flat highway down to L.A. from S.F. that trip is about 500 miles one way on mostly flat straight road. I'm guessing the tire pressure must have been the difference. I'm running the stock size in Michelin LT MS2s.

All that stuff on your roof absolutely crushes gas mileage, take it off when you aren't using it. It always cracks me up how people will drive around with stuff like ski racks on all year because they think it makes them look adventurous.

My best tankful, being topped off was 416 miles. With a 3" lift and 285 Duratracs. Woohoo!

My bone stock 2012 TE w/ 44k miles averages roughly 17-18 in the winter (70% highway) and 19-21 in the summer.
You're just leaving break in, where gas mileage is always a little lower than to be expected. You will gain 2-3 mpg over the next couple thousand miles, and that will reflect your mileage moving forward.
This day in age? its a 4.0L V6 (which is a rather large displacement v6), with a gross weight over 6000 lbs, and its as aerodynamic as a brick. What did you expect?

My observations for one year.
Bought the truck with 31K on the odometer. It is now at 50K. I've been driving it for 14 months. From the first week I've been running the Toyo Open Country MT's generally set at 38psig.
I live at 4200 feet elevation'
Relative humidity generally around 5 to 10%.
Winter temperatures -8 to +40.
Summer temperatures +40 to +90.
Here in rural Nevada traffic jams simply do not exist.
A few observations:
1.Typically the truck does not settle into its best economy until almost 12 miles of driving from a cold start (winter or summer). My guess is it takes that long for the oxygen sensors/cats, etc. to settle into their optimum temperatures.
2. These E rated tires take a few miles to warm up, soften and become round.
3. Probably some time is even spent getting gear oil, tranny fluid, etc to good temps.
Anyway:
On flat highway, after the 12 mile settling in, I get a consistent 21 to 22 mpg.
Around town, after warm up, it varies from about 15 to 17 mpg.
Off road, being in low range all day it will do from 12 t0 14 mpg.
Note: I reset the mileage computer at every fill up.
Many times I will reset again just to figure out exactly what I'm getting at each condition.
My mileage calculator and the odometer are dead on with the Toyos.

It's used on a regular basis to carry my hunting/camping gear. My mods are not to "look adventurous", they are for function.
I'm not saying you personally do that. Just answering your question of why your mpg is below average.

Been dialing in my tire pressure since throwing the Coopers on the truck. Lots of in town driving too... I need to 're-learn' with the heavier tires...
What app did you use to configure all that?
SCRATCH THAT.
Found it on the App Store [emoji1417]

What is the app though? I can't seem to find it searching for keywords like "fuel calculator" or "mileage" or "mpg" etc. I haven't filled up yet, would be cool to keep track from tank 1.
