Hi all I have just purchased my first four wheel drive a 1990 petrol auto landcruiser wagon.
My wife and I want to do a little four wheel driving for a change.
The problem is I can only get 330 klms per 80 litre tank.
I would like to know if this is to much per klm or is it average and if it is how do I fix the problem besides getting the injectors cleaned.
Also I do not think this landcruiser has don very much four wheel driving as it used to belong to Alan Borders wife

At 24l per 100k's its on the heavy side , even for a Petrol.

Right foot is the biggest problem.

I live on the sunshine coast and drive to Brisbane along the Bruce highway every work day and I actually stick to the spead limit so I dont think that I have a heavy foot at all.

I had a GQ Nissan Petrol Auto with one careful wife driving it most of the time during the week we often only got 275kms per 90 lt tank.
But on the country trips when it shifted into overdrive it went up to nearly 500 kms per 90 lts.

I would think that it is a bit high - though petrols do use more fuel per km than diesel. Take it to an authorised 4WD mechanic, preferably one who works/knows Landcruisers and have it serviced/tuned etc.

Being a 1990 model petrol auto, you are really behind the eight ball with regard to consumption. these 3f motors were prone to like drinking fuel, and yours sounds to be close to the mark. as a comparison, i use 20l/100kms with mine, and it is multivalve etc
Your main tank holds 90l, so u either have gas and have ommitted to state that (which would explain the high consumption) or you have not emptied it completely yet!
How does it run? Does it start ok, is there any missing at idle??
These motors had a big problem with inlet manifolds warping and valves burning.
b4 you bag me out, walk a mile in my shoes, then your a mile away and have my shoes :)

We have a 90 Patrol Auto Petrol and have also an lpg conversion. It holds 115 of lpg and is good for 450 in the city and 550 country. And at $40 aprox a tank is great. Also hold 70 ulp which gives another 350 or so. Some people bag gas but it works for us.

That would be normal for a 90 model with an auto.

You think that that milage is bad just wait until you get it off road. It will be a lot worse.
