11mpg around town is possible. I once recorded 17 mpg on road trip through Banff/Jasper.
it is in Canada, you sure it wasn't kilometers per gallon?

It makes up for lack of power by getting poor mpg.

I live in California, so motor swap would be a pain. Too bad I was looking for something older that was cool to drive on trips.
I accelerate up hills in 5th gear where before I would be dogging it at 55mph. I drive 80mph every week on the beltway. On the highway I usually go the speed limit, which is usually 70 or 75 around here. I did some other work to my 3FE but the H55F is the biggest performance booster you can do, with the original engine.
I'm Looking at purchasing a 1989 and I've never driven one. I've heard they are under powered. 155 hp isn't alot. I was wondering about cruising speed and hills?
Its interesting your point about tire size. Mine originally had 30s on it but i replaced them with 33s and it seems i have less of a problem going up hills. My acceleration is slower but i can actually go faster up the hills. Its definitely keeping my operating RPM at highway speeds lower than with the 30s.The FJ62 has good torque, but, not much HP. The speed up hills is directly related to the tire size. To keep any pep at all do not go bigger than 31 inch x 15 tires. When mine had the original 28" size tires on the original rims it was noticeably faster up hills. I run 31 inch all-terrains now on the stock rims with an EMU lift and I go down to 3rd gear and run 3700 rpm up the grapevine going North - so, from Castaic Lake up the Grape vine to Pyramid Lake, I can stay in this gear and rpm. This keeps me in the 2nd and 3rd lane, passing a surprising number of cars and trucks. This is a long tough climb with many lanes where people really goose their cars, ie. a lot overheat.. I am not convinced that the auto tranny hurts you climbing hills.
Otherwise, with 31's you are mostly in overdrive on the fwy. If you are really going fast in overdrive and you want to maintain that speed when you come up to an incline, sometimes, you will have to downshift to 3rd gear also.
These trucks are all about gearing and being in the sweet spot under heavy load, so, you have to think more and plan more.

That makes a lot of sens. Now does the width of the tire make a difference too? if you have less rubber on the road would that mean you have less rolling resistance or is that negligible?On hills, it depends on where your top out speed lands. You have only so much power to overcome road load but once torque starts to taper off you have usually reached your max speed. This phenomenon is exacerbated by the huge gear ratio gap between 3rd and 4th gear. You can often find you top out 3rd but cannot hold speed in 4th. The larger tires move that top out speed upwards allowing you to reach a higher speed.
Of course that also reduces overall thrust in 3rd so there will be the occasional grade that puts you in 2nd gear where you might have been able to pull in 3rd with 31's. ...
