lift = lower mileage.

You want it to get the best mileage?

keep the small tires and drive 55..

low and slow is the key.

When I have numbers on my rig. (35's 3.70's and super short) I'll post them

[masscrusher]

This past weekend I had a chance to chat for awhile with Jim Chenowith, and I asked the same from him. His answer was:

A properly maintained 60 should be in the 16 mpg.

He also talked to a larger group and Aussie mirrors, auto transmissions, lifts and improper gear to tire size ratios will affect mpg. Not in a good way.

[Fearnofish!]

I don't drive on any highways but I get a constant 14-15 mpg. COnsidering the mods I am pleased. I only run 87 octane by the way.

Just got back from a 2200mi. road trip a couple weeks ago. Went from Ohio to YankeeToys fall gathering up in New Hamshter, then over to the coast of Maine for a few days, down to Monticello, NY to crew a ProRally the next weekend, then all the way across Pennsylvania from the NE corner to the SW corner.

On the outbound leg(OH-NH-ME) we went 1017mi(true) and burned 59.33gals of cheapsh1t unleaded.
Avg fuel economy was 17.14MPG.

Then there was the miles from Maine to the Rally and use of the truck by the rally team. We lost track of miles and fuel consumption during that part.

On the return leg (NY-PA-OH) we went 595miles and burned 39.2gals for an avg. of 15.18MPG.

Outbound was across northern OH, PA and NY on I-90 at 64MPH, w/ a stock front bumper and no roof rack.

Return leg was w/ an ARB front bullbar & a roof rack loaded w/ 33" tires (thanks Annie!), fighting a headwind through the mountains of PA. Sometimes going a little faster than 64MPH 'cause we were ready to be home by then. 11 days in a stock FJ60 front seat makes a person want to get home.

Next FJ60 will get better fuel economy due to a better cylinder head (more port work) and a Fairey OD and a chrome header.

[gnx7]

Just dropped off my FJ60 to finally get painted and the rust repaired in SoCal.... averaged 13.1mpg going 65-70mph all highway. stock gears, 4speed manual, 33x12.5"s, stock bumpers, no roof rack.

I'd like to get 15mpg... it hasn't had a tune up in 20K miles... probably time.

[dkalley]

I average 15mpg highway (not coming close to the posted 70mph) and something sick in town, about or less 10 (lots of stops signs in carson city). The previous owner told me 20mpg and I cursed him the first month I filled up. Coming back from the bay area last time I filled up at about 200 miles, 10 gallons. Totally psyched I told my wife at the pump next to me who reminded me I actually got over 230 miles on an accurate speedo. Gotta love flat horizons...The trip over 88 gobbled up that and I averaged around 14.

1988 FJ62
SOA with 35's
4.88's, 3F (Carb, no smog), 5 speed

All tests were done with GPS (mileage & speed) :

Daily drive to work: 15.5 mpg

Weekend towing 2000 lb offroad trailer, highway cruise at 65 mpg, one day trail was mountainous : Averaged 13.5 mpg

250 mile highway test run, slightly hilly, no mountains, averaged 73 mph, pushing at times to 86 mph to overtake: 14.85 mpg

Steady highway run at 65 mph :

Serious offroad with thick sand and a heavy foot: 11.3 mpg

[CodeRed]

10-10.5 regardless:(

I have installed a K&N filter, had a complete tune up and it's all stock with no racks, stock bumpers, etc.

About the 3rd tank after the tuneup and K&N, drove like a little ole lady, all the "right" stuff = 10.5

2 tanks later, drove it like I stole it...= 10.5

Every check since then has been in the same range...hey, at least it's consistant...

What are you driving?

[GLTHFJ60]

I just took my mileage over my trip to Connecticut this weekend. I had 20 miles of regular city driving on my tank when I started my 140 mile trip. After that 160 miles, I put on another couple miles and filled my tank.

I was suprised when I got 15.5 miles to the gallon. Very plesantly suprised indeed!

I have a freshly rebuilt carb (myself) as well as new fuel, air and oil filters and next-to new NGK plugs.

[notatreehugger]

I just got 17mph!!!! If you can't tell I'm real excited. I got this with a complete tune up, new wheel bearings, u-joints, and oh yeah, 33x10.50 w/stock gears. Down side, I only have enough power to run 71.

[tclndcrz]

11 city 12 highway

fj62- used to get 10 mpg and then it randomly improved

[Team Zissou]

The Air Force moved me from Tacoma to Champaign back in November. I weighed in at 6200 pounds leaving, not counting myself but including my trailered motorcycle. 2,478 miles later I got to my folks place in Cincinnati in time for Thanksgiving.

Avg gas mileage: 17.1 MPG limiting RPMs to no more than 2500 (about 65 MPH, give or take)

Since the OME lift, and mud terrains, I'm down to about 15.6 MPG highway. We won't discuss in town driving.

[DirtyLittleSecret]

Gad. Something must be wrong with my rig.
Just bought it yesterday and promptly drove I5 for 300 miles. Filled it this morning and calced out 17.8 mpg. Stock rig with a roof rack. Will be doing a full tune up tomorrow.
Perhaps with a lift and some 33's...

[DCM36]

1988 FJ62
14.5 city/17 Highway
If I stay at 55-60 mph, I'll do a little better.

[JimCrow]

I know this is an answer to an old post but I was cleaning my glove compartment out today and found the orginal window sticker for my 83 FJ60 cost $14,142 average fuel mileage 12 just for information, I didn't know I even had it.

I also run 40 psi in my tires.

[CodeRed]

Sorry, been gone a bit....89 FJ62, stock (at the time).

In the shop now to replace the engine. I plan on making sure this engine has "all the right stuff" BEFORE I put it in! This motor only has 78k on it and has been gone over pretty well.

I'll probably re-do the wheel bearings, and rebuild the transmission (if the $$ holds out) whiles she's up in ther air.

I'm currently running Wrangler AT (Kevlar belted) 33-12.50's and a 3" OME lift, and an ARB winch bumper is going on right after the engines back in.

I'll re-post and let you know how it goes.

[Gallo Pinto]

Around 14-15
Never, ever go over 2500 rpm's and my top speed is 55 mph.
The truck is nicely tuned up.

[cnlson]

my first 2 tanks were bringing it back from North Dakota and those 200-300 miles were approx 13.5-14 @ 80 - 90 mph (2wd)

most of the 2wd around town has been 11-12 unless i leave it idling a lot then it might dip below 10

most of the 4wd winter type driving has been 9-11

so far this months gas bill is somewhere around $250. i dream of the days of $1.25 premium

[-Macca-]

FJ62 3F (not 3FE) 5 speed

On 32" BFG MT's, 300km/70L LPG (12.1MPG)
On 29" Nankang AT's, 360km/70L LPG (14.5MPG)

Economy on petrol is better (about 33% more distance / L), but as LPG is less than half the price of petrol I run on LPG 99% of the time.

[Ducks]

Just bought my fj60 running on 31s. First tank of gas says I got over 17 mpg. Yes I know how to divide. No, I don't know if the odometer is correct. Freak of nature perhaps. Either way, I'm happy.

[sirenmoses]

30x9.5's, Aussie mirrors, hauling .4 ton of gravel in the back, mtn driving w/snow: 16mpg. WTF? Happiness x2!

[Mini Goat]

Our best mileage was 15 miles per gallon.

[CruisinFJ60]

my odometer quit working but when i had the 33's and it was working i think i was getting 15-16ish on hwy never getting over 2500 rpm. after that gas disapears. now i think im getting maybe 13?

[RenegadeQ]

10 mpg in the city. Has slowly been inching up to 11 mpg as I work out some issues one by one.

[theside00]

I get 10 to 11 on the highway no matter what I do. Has 33's with the 4:11 gears, winch up front and a roof rack. Tried a tune up and everything but cant seem to get above that. I drive around 2300 rpms on the highway. I am jealous of the guys getting around 16 and 17.

[Jess the gearhead]

I get 8-9 towing a tandem axle trailer at max. GVW, 10-11 towing a single axle trailer and 11-13 highway depending on terrain and how heavily loaded I am. 10 gpm around town generally speaking. The 31's, 2" lift, full sized roof rack and Ford style side mirrors probably don't help...

[vanyoska]

Do you know if what you have would be legal in NY, Cal, Texas or Mexico?
I'm asking, because I may be buying an '83 or '84. One of them needs a carb or intake manifold fix.
I was wondering how to increase the gas mileage as I'll be going on a 2500 mile trip?
But I need to register it in NY (where maybe I can get hlep with the emissions). But then I'll probably need to have it retested in Mexico and then perhaps sell it in Texas (where laws are also strict. So i'm wondering if what yo udid to get this mileage would be legal? Someone can probably get it passed in NY but I don't know about Texas (where it may be bought) or Mexico (whre it may be tested).
Anyway, what did you do to get this great, for an FJ60, gas mileage?
Thanks,
Vanyoska

[vanyoska]

I may buy an 83 or 84 FJ60. Any suggestions what I can do to get better mileage for a very long trip and still pass smog tests? I'm also in NY and you may have a better idea of what's required here. Thanks
