I have a 1988 4Runner. 22R EFI. It has a rebuilt long block in it with about 6000 miles. Truck over all has 223,xxx miles.

It is a 5 speed. What can I expect for fuel Mileage? Of course I use more when going 70 mph then I do at 60 - 65. but what should I expect?

 

I have a 1989 Toyota 4x4 Pickup. 22R/e, 5 speed, 147,000 miles, 4.10 gears, and 33x12.50 tires. I average 25mpg.

 

Do you have to downshift to third on highway hills? I'm thinking about bumping up to 33s but don't have the cash for both new tires and gears at the moment.

 

How are you getting these numbers? The truck didnt even get 25 stock, with 33x12.5's and 4.10 gears I just dont see how thats possible. Even with speedometer correction thats the highest mileage I've seen from a 4WD with 33's. Maybe you have a secret that you need to share with the rest of us?

FWIW: With 32x11.5's and 4.10 gearing, my 135k 22R-E 5 speed 4WD x-cab gets 17-18 mpg on average.

 

Nope! I occasionally shift down to fourth, but mainly where I drive I can just stay in fifth.

Hmm... Nope, not any kind of tricks. I have a new fuel filter, PCV valve, I change my oil often, new plug wires, rotor, cap, and plugs. Umm... Other than that, nothing!

I just put gas in it tonight. 12.3 gallons. I got roughly 300 miles (calculated using mapquest, not the odometer) since my last fill up.

 

^Something aint right, cause 25mpg is alot! I could understand 20, but 25 is unheard of even 100% bone stock off the floor.

Is all your driving hwy miles on flat grade?

 

Somewhat. There's a few down hills and a few up hills, but mostly flat.

 

I'm not sure I believe that....To Average 25 mpg means you would have to have gotten more than that on numerous occasions.

 

To answer the Original question.

My 87 4runner, 5speed, 22re, 4.10 gears, and 31x10.50 tires

My highest reading has been 21 and my lowest 15
Mean average: 17.something

All the numbers are mixed driving.

If you want I can Email you my spreadsheet so you can get a better look at my stats.

 

so pretty much the 18 I'm getting is about right?

I don't have over size tires or anything like that

 

I'd say so. I get around 17-18 and I've got a 1994 Pickup 4x4 5spd 22RE running 31x10.5 tires.

 

When my dad's 82 (22R) rolled off the floor, it peaked at 27mpg. It's about half that now...

 

Yeah. I got around 27 last winter.

Highest I ever got was 27, lowest was 21.

Last tank I got a little under 25, 24.634 to be exact.

 

86 4runner, 22re 5spd, 5.29s and 35s and i get 19-20 MPG

 

We have the same drivetrain...yet you have bigger tires than I....but you are getting 10mpg more than I am?

Something isn't right with this.

 

yeah somethin isnt right. i have a 88 22re with 250,000 miles and while i dont know my exact mileage, i filled up on sunday, and had to put 20 bucks in on wed then another 20 tonight. so im guessing about 12 to the gallon.. somethin aint right with mine methinks.... what r ur guys secrets?

 

Your not taking into account your large oversized tires.

 

im kidna thinkin its the PCV... im burning oil BAD and burnin gas BAD ever since i put the checker PCV valve in... im thinkin they gave me the wrong one....

 

biggest diffrence is your driving style, i drive like an old lady, and get 20. Most i ever got was when my truck was stolen when i got it back i calculated 22mpg for that tank, i want to know how they got better milage than me

 

hmmm.... that could have somethin to do with it... on freeways i speed.. simply cuz if i dont it drops to about 45-50 goin uphill. and that seems to burn more gas then flyin down the freeway at 80 then goin up it at 60-65.
