Castrol Magnatec 10w-40 non-diesel, used in my Pathfinder 2.5 turbo diesel R51 auto (non diesel particulate filter model). Change the oil and filter every 10,000km and now has 155,000 without any problems.
Change all other oils (auto box, transfer box, both diffs) once per year.
Diesel filter and air filter every second oil change.
Never changed the cooling fluid - often thought about it, but if its not broke....
