I have recently (yesterday!!!) purchased my first 4wd and I am stoked! Yes, she is a little worn, (530.000ks on the clock) but all up still in pretty good shape including the turbo diesel engine. Well, kind of, except perhaps for the the 'excessive' fuel consumption. I only get around 300ks on a 90 litre tank...70% of which I used up on the open road and 30% in city traffic. I was hoping there was a hole in my tank but maybe she is just a very thirsty girl:-)
Does anyone know how much the average diesel consumtion for this car should be?

Thanks guys.

That should be a Hj 62,
12HT motor should do better than that towing a 30 fot caravan!
somethings really wrong for it to be using 30 liters/100, I didn't think its was possible!
It SHOULD be no more than 15l/100ks.

30lt per 100k's...I'd cry mate no matter how much I loved the car!

Seriously something wrong there I reckon. Never owned an Fj62 diesel but I use to have a cruiser with a the petrol 3F motor and it was around the 18 - 20lt/100k mark.

I would have expected a TD to be at least the same and probably better.

Have it looked at, being a new acquisition, you probably want all the oils etc checked or replaced anyway.

On the down side, I'm not a mechanic so don't listen to me! :-)

Happy travels.

I had one of these for a few years, last of the good strong offroad Tojo wagons ripper vehicles but a bit uncouth by todays standards bullet proof driveline and diffs Mine averaged 23 mpg what ever that translates to in metric Bought if for 24k traded it on a petrol 80 series 3 years later for 27k Loved that truck should have hung onto it, Cheers Rob Berrill

HJ61 and sitting on 110 klms you should get over 700 klms. fj62 is petrol version. Plate which will tell you is on firewall under bonnet drivers side.
It sounds as if your boost compensating valve on injector pump is jammed open re:- black smoke and excessive fuel usage.
I change injectors every 200000 klms and injector pump overhaul at 350000klms.

Hello,

Assuming it is in fact a HJ62 with the 12ht you should get much better than that. I have the less efficient 2H with aftermarket turbo and I get 12-13L/100km on the hwy and 13-15L/100km around town and that is with an auto. Basically get 5-600km out of a tank around town. As already mentioned check boost compensator, injectors, injection pump and timing etc.

Cheers,
Dave

AS said by others it should be a HJ62 if its a turbo diesel.
Same model as mine and you should be averaging around 12.7 to 12.9 litres per 100km if all is running well. I did a 180km trip yesterday after filling up and the gauge is still showing about 3/4 full.
You definately need to have things checked.
ON the positive side you have purchased a solid old 4x4 for your first one - they are a great unit and you'll have lots of good times with it.
Cheers,
Glen

A 60 series with a 12HT originally sold in aust is a HJ61
The 60 series with the 3F petrol is a FJ62

There is no aust spec 60 series with the model designation of HJ62

hj60 was std diesel. hj61 was factory turbo fj60 was 2f and fj62 was 3f....you should easily get 10l/100 out of a hj61 on the highway at 90km/hr.
Try some unleaded in the tank....see the post today

Have you checked the handbrake!!!
HJ61 should be getting around 13.5 litres per 100 around the city. If it is not there is something really wrong!

Hi Everyone,

First things first: thanks for all the feedback and the helpful suggestions...embarrassinglly acknowledging the mix up in models- it appears I no longer own an FJ62 but rather a HJ60 with a 2h engine that has an aftermarket turbo fitted- ! In fact, it probably is more like Davo_60's rig.

So I guess I shall take my new purchase to the workshop next week.....to get the injector pump and valves checked out. Just like you mentioned OldSquizzy- I have a fair bit of black smoke coming out, fuel consumtion is excessive (no doubt!) and also a bit too much oil in the engine....
Thanks again gents,
Cheers,
Dan

Well then you dont have boost compensation. More than likely that someone has adjusted the rack on the injector pump to give more fuel due to aftermarket turbo.
You need a fuel injection workshop like United Fuel in Perth more so than a normal workshop.
And as usual nothing to do with said company other than to give them copious amounts of money now and again.

Dan,

Thought we had the answer there for a minute. Putting diesel in an FJ62 might account for the poor consumption ;-)
