..."I get a pretty consistent 34 MPG..."


Can you please explain your method of calculating MPG's? I fill up and divide the miles I've gone since last fill up by the gallons I just put in. This is the official fleet management method impressed on me by my father. I know a lot of people pay cash and only put in, say $10 at a time. There's no way to be accurate that way. 22RE is supposed to be about 20 mpg. We get 16 mpg with a teenage driver and an exhaust leak and old plugs.

Max-85

That's exactly the method I use. The longest I've gone at once was 500 miles and it took 15 gallons, which surprised me because I thought I had a 13-14 gallon tank. That was a straight stretch of interstate highway with a few good downhill sections which I took advantage of, so gravity helped get that number up there a bit.

The truck weighs 2,850 pounds unloaded, and I'm an excessively tame driver. 34 is my highway figure, using any decent downhill stretches to my advantages by dropping into neutral. In town however, it does drop back down into typical 1980's pickup truck numbers, ranging anywhere from 20-28, depending on my mood, traffic, and how generous the stop lights are.

If the driver's willing to act a bit more like Gramma behind the wheel, those numbers'll climb, but if you're talking about one of your 4runners, I'd doubt it'll get any better than 26-29 after a tune up and an attitude adjustment. The old R-E is a good engine, but I'd say weight is its arch enemy, and a 1990s generation of 4Runner, especially if it's packing an automatic, 4 wheel drive, and big tires, is gonna find that engine's limitations real quick.

I do drive like a blue haired old lady, so take my info for what it's worth. I don't expect anybody on the planet to wanna drive like me, it's understandably boring. But it really pays off on long trips, big time money savings.

Anyway, hope that makes things clearer. I'm an open book if you've got anything to ask me.

Though I am about 4 years late to this thread, I can tell you that I tried to run my 1985 Toyota Hilux with 271,000 and the 22R-E into the ground.
I had bought her from a kid who used to "Street Rice." He got her from his father, he purchased originally from a dealership in Los Angeles. Anyways the kid took it to Red Line every gear and just destroyed it. Before him the father used it as a gardening truck for 22 years, and a commuter up until 2007. By that time it had 200,000 miles on it. The kid took it for college purposes and enjoyment (obviously because she's a Yota.)
when I bought it in 2013 she had close to 255,000 miles and it had a Spun Bearing/Rod Knock between 2,200 RPM'S and 3,300 RPM'S. It was definitely pretty bad haha, but besides that I drove Her up until 2015 with that same knock until I got tired of it and swapped in a Nissan SR20DET... They both had the same MPG'S at around 26 or so, until I built the Nissan Engine.
The 22R-E was definitely great and cruised 75 over the Grapevine with ease in 4th gear, but doesn't compare in power with the SR20DET... Especially after she made a tad bit over 500 Horse Power Lol. I then did a 85 Chevy S-10 rear end for the 4:11 gearing, pozzy traction, and the extra 1.5 inches of extra clearance in my bed for slicks, without having to tub of course.
I think my next build will be a turbo or bi-turbo 3RZ. After I put some mileage on it and see how it compares to the 22R-E and SR20DET after the initial build of course.
Mahlos for making this thread by the way! Definitely some interesting input!

Lol that this thread got dug up 3 times from the grave.

Just a note on mpg, gear ratio makes a huge difference, big tires can hinder mpg if they are extra wide tires, tall skinny can give better mpg. I get 22-27 mpg with my tacoma 3.4L 4x4 standard cab 5 speed with 4.10. When I drove my 86 xtra cab 2wd 22r pickup it got 25-30mpg and that's with a high float level in the carb and a front caliper hanging up, but it's gear ratio is the same as the guy that got 35mpg from the same truck, the 3.58:1.

I've heard from two people now with 2wd T100's with the 3rz (2.7L) getting around 27mpg at highway speeds.
