G'day everyone, I've got some questions regarding oils.
I was at Supercheap Auto today to get diff, gearbox and transfer case oils. I'm not sure whether I've got the right stuff, and other threads I've searched didn't give a clear answer.
For the gearbox and transfer case, I got Penrite semi-synthetic 75W-90. Now the service manual says I should get 75W-90 GL4. The Penrite oil says it it designed for API GL4 and also for GL5. I read somewhere that you definitely shouldn't use GL5 for the gearbox, so is this one OK or not? Also the manual recommends 80W-90 GL4 for the transfer case, is the 75W-90 GL4 OK for this or not?
For the diffs, the manual recommends 80W-90, and the same with LS for the rear. I got Castrol Axle Limited Slip 90. Is this fine to use? And is it ok to use the LS for the front as well as the rear?
Another question: the manual recommends diff, gearbox and transfer case oil changes every 40,000k's. Is this often enough, especially if often driving short distances, and doing regular small and big trips throughout the year?
Finally one other question, do you guys recommend going genuine only, or is it alright to go aftermarket? Are there any kits that make regular servicing cheaper than buying individually? The problem I've got with kits is that I've got a Zd30 airbox, so the air filter is always the wrong one. Cheers, lots of questions but I'm a newbie trying to learn!
