the hilux diesel in aus isnt amazing on fuel.
im not sure why that motor isnt offered here though.
Compared to the 4.0L V6 in the hilux it is quite a bit better though. I was a steady driver and would only ever get a maximum of 430 kilometres to a full 70L tank.
What is amazing is the Volkswagon Amarok. That thing gets over 1000 kilometres to a tank any day of the week in the diesel. Damn pricey up front though!
