those tires are part of it, but still should be close like the guy above; most of your driving is proly in the city; Neutral = your best friend, use it between lights, between stop signs, coming off the freeway, etc. Do your basic tuneup stuff, dist. cap, rotor, sparkplugs/wires, etc., keep the tires at least 35 lbs pressure, and do a couple of Seafoam treatments. That is the most basic stuff to do; if it is still bad, then come back here and tell us what you have done to that point; you then have some other issues...

 

Coasting in Neutral(idling) uses more fuel than coasting in gear. 22RE's like most engines, cut fuel when your engine braking/letting off the gas. The only advantage to coasting in neutral is there is no drag so you can coast a longer distance without having to touch the gas.


22mpg on my last tank. Most of it was offroad and on back roads, lots of steep hills. I was heavy on the throttle as well. 88 4runner, 22RE, 5spd, 235/75/15 Michelins. I just adjusted my TPS and fixed a big vaccuum leak at the EGR, really happy with the fuel economy its getting now.

 

last tank i got 250km to 50 liters.... really not good. I have a tendancy to rev it high because it lacks power at lower rmp's. 22re with 31x10.5's. plus i've been using 4wd a lot and doing some snow plowing. I'm gonna do some highway driving with the next tank and see what happens.

 

Island Yota; I don't believe that for a second- when I put my engine in idle, coming off a freeway, the rpm idle on mine is about 700 rpms, and just stays there for the 1/4 mile or so to the first off ramp light. When you are in gear, your engine is turning as fast as your tranny is, and so your rpms stay high- faster engine turning means more fuel being used, period.

If your truck has a tachometer, watch it, you will clearly see the diff.

 

On many carbureted engines that would be true because most don't cut fuel to the engine on deceleration. With EFI, the ECU cuts fuel to the engine when decelerating to almost 0 which means, you are using less fuel than you would be at idle. Im serious, Read about it, more RPM doesn't always = more fuel spent.

1993 4wd pickup, 22re, 5 speed, 17-18 mpg, freeway and in town combined, commuter. Always thought I'd get better than that!

 

17mpg all around........Highway or City, I get 17 LMAO

 

18.5mpg mixed, just a hair shy of 20mpg on the highway. "Mods" in sig.

 

DGB; do what my post says above; bet you hit 20. Try it without neutral, on one tank, and then next tank using neutral-- that is, after you do the other small mods...

 

i have always know this but do you know how far back this applies? i know it says fuel injected but this can go back to 1980 with fuel injected those it? im mean gas as cheap back than lol

 

I would say, this would have to depend on your car's computer, and what capability/software/ram storage it was loaded with. If your ecu's designers didn't think about fuel cutdown on slowdowns, then yours won't do it.
I have no idea if my 88 does it, I doubt it does, and I seriously doubt anything before about 90 or 92 does, maybe even as late as 95', since that was about the end time, of all the old large item, surface mount, 386 technology.

 

id try it too but I just don't feel comfortable coasting around in neutral.

 

17.5 MPG (mixed city/highway)
1988 4 runner 3vze
fresh rebuild (bored 30 over)
Accel Plug Wires
Bosch +4 plat plugs
custom intake
31x10.5x15 BFG At's stock wheels

 

31's w/ 4.10 gears 22re 5spd
I was getting 20 mpg.
I blocked off my EGR and put 4.30's in it
23.5 mpg on my last tank.

 

Wow!!! that's pretty good, is it not legal to block off your egr? and if it is
not, then describe how to do it please...

 

It is not legal, I just did it to test whether or not mine is working properly. I will unblock it after a couple more tanks then check my gas mileage again.
In theory, the egr should increase your gas mileage if it is working properly.

 

100% flat highway, 65mph at 2200 rpm = 19 mpg
City/highway - 50/50 = 15.5 mpg

92 3.0 auto
33x9.5x15 bfg at at 40psi
4.88
4" lift
manual locking hubs
no other mods that add weight or drag

I wonder how many of these posts with taller tires are accounting for the odometer reading being off?
