just bought a 4runner
 

very proud owner of a white 1998 4runner. 137k, 5 speed. neat vehicle. paid 3899.

what are the good mods for the best fuel economy? please dont say leave it parked in the driveway....etc. i hope i can get near 20 with it on the highway. i will of course be doing a full tune up. is the 3.4 picky about spark plugs like the 22re?

Tons of info about both if you do a search. You should get 20 mpg as it is on the highway.

All right! another happy 5 speed driver! Looks like you got a good deal onher too. As far as fuel economy I'd say keep as much weight out of as you can (cargo you dont need) Keep her tuned up ie. plugs, filters fluids changed at proper intervals and you might wanna switch to synthetic engine oil for starters, less fricton=better fuel economy. The plugs I'd use is the good ol' factory twin electrode nippon denso's fromthe stealership, thats where I got mine but u coule doasearchadget the part number andgo to autozone napa etc. Bump for a good buy on your new ride!!!!

x2. I get 22 with 285's and a TJM bumper up front. Make sure your spark plugs and wires and good. Check your air filter as well. You can change everything over to synthetic to maybe get a little more mileage. Lastly, speed is everything. I can coax 23-24 mpg out of mine if I set the cruise at 60-65 where-as if I go 75+ the mpg's drop to 18 ish. You should be able to do better than this if you're still stock.

Are you serious???? Do you coast in neutral a lot? and on stock 4.10s/4.30s?

I get about the same on my stock 98 speed. About 22-23 under 65 mph. After that it's having to work to hard to push that brick through the air. I got 26 one time with the 4 wheel drive on. That was going like 50 mph for the better part of a day.

heres ye a fuel catalyst says it adds 2.5 mpg http://www.4wheelparts.com/prodDetai...artNo=APRF3824

let me know how that fuel booster thing works out for you. i'll be over here working on my spaceship in the meantime.

There's a good waste of money.

never said it was for me... just an idea i know its a waste of money.. aint we suppossed to help each other out here? ssupercoolss, lets some pics of that spaceship smart ass

Sorry,I was helping people out by how there's no true real world proof those things work as promised.

take it easy yoder - i was just joking around. you would also have to drive like 9000 miles before that was paid off.

Good Point.

hey bro welcome. best mileage possible is to keep her in the driveway...
jp man.. id use dual diode plugs in her, keep en gapped right, keep the air filter clean, change oil religiously, keep tires inflated and rotated/balanced, and you will be good to go.
