castrol tection (now vection) 15/40. Thats what i used in mine and was faultless.

Just as a side issue do you have a water / fuel separator before your diesel filter in that ute??

If you don't, install one. if you get water in your fuel it can overwhelm the filter and get to the common rail pump before it sets off the water alarm on the dash. result = new common rail pump and huge bill.

Mine had a racor r12 unit. The sort that you put into a boat with the clear polycarbonate bit on the bottom so you can see if there's water in it. Just change that filter and don't worry about the factory one. Racor is a finer micron filter that the standard hilux filter ( i think its 20 micron.)
