I changed all the driveline oils in our 2004 STR last week end and used all Nulon oils.
2 x four litre containers of their 75W90 semi synthetic gearbox oil for the gearbox and transfer case.
3 x one litre containers of their 80W140 full synthetic differential oil for front and rear diffs.
First time I've used Nulon oils, so as yet I can't give them a big wrap, but so far so good.
Cheers,
Rusty.
