You know that saying, "If you have to ask, it's too expensive." Well . . .

[lowtideride]

i get 12...

[ColoradoFJ60]

I get about 6 MPG's right now. I went through a whole tank and scraped out 170 miles. Probably has something to do with my clutch slipping.

[svo_jon]

On my last trip from Bend OR to Santa Cruz CA I avreged 17 miles to the gallon and that was moderately to heavily loaded.
I have a 60 with freshly rebuilt engine, header and 2.5" exhaust, Downey torquer cam, D.U.I., and a good tune.

[lovetoski]

That is outstanding!

[Benji]

I get 10 some days and 14 others. It really depends on the driving conditions.

[ridgerunner]

A friend's '83 FJ60 gets 17-20mpg, but that's with stock tires, no smog pump (every other piece of emision equipment is there) and usually 55-60mph on the highway. He is the most meticulous person I've ever met, and everything on his truck works perfectly.

[magFJ60]

Mine gets about 10 anywhere, but I haven't checked since I cleaned the carb and replaced the air cleaner...hopefully I can at least get 2-3 more. Anything helps!

[Moabut]

in maryland, my '85 gets 12 in town and 15 on the highway, cruising anywhere from 65-80mph. i run crown brand 87 octane with a header, non-usa dizz, aisin carb, no smog stuff, an electric fuel pump and 33"x10.5" BFGs.

E

and 36's when you say stock, you mean 3.70's. how do you turn those meats with 3.70's?

[2badfjs]

runnin 35's with 4.11's right now average 12-13 mpg 200-250 miles per tank. not quite sure how accurate that is. i'm sure it will change when the 4.88's go in.

[mattlock]

Not sure if my odometer is mis-calibrated but I usually get around 15.7 to 16.1 MPG on the interstate. I firmly believe most cars have a sweet spot that allows for maximum effeciency. All I do is listen for signs of the engine working hard and I slow down a little or speed up. It is usually not too hard on longer roadtrips to do this.

In Colorado, my '84 gets 10-12 in town and 15-17 on the highway, cruising anywhere from 65-80mph. i run 85 or 87 octane with a stock exhaust manifold, usa dizz, aisin carb, full smog stuff, a mechanical fuel pump and 33"x10.5" BFGs.

[Cookiemonster]

30mpg. Down hill, tail wind, in neutral, with a JATO. That is w/out the Dilithium Crystals.

No Idea. Never bothered to figure it out. It's like a 69 Dodge RT 440, about 5gals per mile....................

[Kellogg21]

Mine is an 83 FJ60 with 33's and it is timed higher so i have to put an higher octane gas. It gets around 14-15 mpg no matter what. Does anyone know how much a snorkel helps on the gas mileage?

finally tuned and smogged (passed that is ) running 31's and getting 11-12ish

[baloo]

WIth the 3FEI = 10-16 mpg 18 once with the vortec range 10 -16, usually 14ish no matter what I do. The things have the density of a brick and the aerodynamics of a...brick. I also drive a Tracker it get 25-30 but only hold two people and a six pack. My best mpgs are from my bike I go about 40 mile per beer/burger and I guess ipedalling helps with stress too.

Sounds close to mine (1989). I get 13-14 on highway, but I usually drive between 75-80. Around town is more like 11. Towing 2000lbs boat...9-10

Best ever was a few tanks @ 15 mpg right after exhaust upgrade, but gone back to usual over time...maybe time for new cap, plugs, and fix the fan clutch.

[cbmontgo]

Some of you guys are like fishermen telling tall tales about gas mileage! I have an '95 FJ60 totally stock that gets 32 MPG towing a 12,000-pound horse trailer full of buffalo at 90-95 miles per hour up a mountain pass in the snow with a head wind of 10 knots and three overweight women in the back seat.

Back to reality, I get 9 in city and 12-13 on the highway.

[cbmontgo]

Sorry, mistype. It is an '85 (not a '95) FJ60 that is so amazing as I mentioned before.

[Cruisin'Carolina]

14.3 on the hwy, don't know yet what it does around town...

[zmontgomery]

In my daily commute I normally average anywhere between 13 and 15. This is mixed highway/city driving. However when I do straight hiway I'll get between 17 and 18. I do have a brand new top end, carb, platinum plugs, and exhaust system though, so that probably adds to it. I think these numbers are pretty good too, considering that our expedition got 14 all the time, a new H2 gets 9, and my buddy's suburban gets anywhere between 9 and 16.

[Cookiemonsterette]

Around 10 gallons per mile. It will be nice to eventually do a diesel swap out. Actually it's an 85 60series and mpg right now is around 12-13.

[ColoradoFJ60]

I get about 200 miles from a $40 fill up.

[FJ40Jim]

My current '87 FJ60 gets 16+ MPG on the hiway, 13-14 in town. Numbers are corrected for odo error.
I drive at 100KPH indicated (65MPH true) max cruising speed. Drive like grandma in town.

The truck has only 120K TTAF, 2K SMOH

During the OH it got honed stock bore, polished stock crank, moly rings, oversize stainless valves, port & polish, milled for slight compression bump, desmogged per the diagram in the tech section, carb rebuilt for efficiency, distributor recurved for efficiency, new OEM exhaust, blah, blah

The truck doesn't have the huge FJ62 mirrors, ARB roof rack, winch bumper, etc.

I think it could get another 1-2 MPG w/ a header, but haven't spent the money on that yet. Not 'til something goes wrong w/ the current exh manifold & pipes. It would also help to swap the 31x10.5's for some 235/85R16, but the wheels cost money.

[87CRUSR]

I avg about 11 mpg with stock tranny and 31" tires. Well tuned, Heavy stop n go So Cal driving.

[franko5]

I've got an 89 FJ62 and on the Seattle hills i get about 10 mpg in the city and about 13-14 mpg on the highway.

[adidasprof]

My 1990 FJ62 get between 12 and 15 mpg. I do most of my driving on the highway. Bought it last year in Phoenix and drove it to Atlanta. 75-80 mph just about the whole way and still got around 14 or 15 mpg.

[WALoeIII]

Good question. I will figure out what 3.73s and 33s on an FJ60 gets. I have ~15% over drive (28 -> 33x12.50 ATs) so I'll calculate it with that math included.

[azaussie]

If I take it easy in the city I get a little more than 10 mpg but if I don't then it is less than 9 mpg. On the freeway I get 16+ mpg.
