The V8 is economical & it sounds like the Navara uses about 14.5lt 100k's?

And the fact diesel was nearly $ 1.60 a liter over easter in the eastern states,what was it in wa
Could be a couple of things on a KA24E. Brakes dragging, cooked ECU autolearn, or a combination of issues.
Best place to start would be to feel if brakes are really hot after driving.
Then try unhooking your battery for ten minutes and pressing the brakes, then hook the battery back up and go for a slow drive.
If you're still having the problem, you need to do a ground up EFI diagnosis. First up it helps to service the vehicle, then start the EFI diagnosis, you can google this but basically make sure you've got spark, fuel and compression. If any one of these is not quite right you'll use more fuel.

If it's a petrol, it's pretty good - Joe's figure of 14.5LPHK is about right and is better than our D40s, the petrol models get upwards of 15LPHK. You might have a lighter vehicle (the D40s are about 1980kg empty) so I would expect a little less usage for that, but it's still an odd shape - not very aerodynamic - travelling at highway speed would need a fair bit of fuel to keep it going.
Like Dion said, check the engine over. Air filter and spark plugs are common items that can degrade and impede a vehicle's economy.

The Navara spec Z24 is carby.
There a old design, based off the L series engine.
Economy sounds about right. Extractors, and a tune will help.

14.5 for a Z24 is actually pretty reasonable.
Electronic Dizzy - might be a couple of options. There was an electronic dizzy for the 8 spark version used in the states in the Navara, and possible some aussie cars (but not the 4WDs). Let us know how you go.
Found this little one on ebay usa. Not sure if it's electornic, but apparently its good for all models, including 4 cyl, 6 cyl and diesels

I want to know which spark plugs you're going to hook it in to on the diesel model.
There's a seller that doesn't pay attention. I'd warn anyone away from them.

good one....
There is a throttle body injection manifold for the Z24 that maybe came out in some early pathfinders, but note exactly sure. Might only have been in the states
In fact here's one. I reckon it might even sit on your existing manifold in place of the carby. Not sure about electronics. Might be an ecu somewhere, couldn't tell you.
For a bit of extra work, a KA24E head will bolt on the Z24 block - think you have to block up one oil hole or something, and swap the cam gear over (Z24 - twin timing chain, KA24E, single timing chain). Also needs different exhaust headers and ecu and wiring. But then you have full injection.
