I've got an '08 G35 w/ AWD and am planning to change the differential fluid soon. The spec it calls for is
Quote:
Genuine NISSAN Differential Oil Hypoid Super GL-5 80W-90 or API GL-5 viscosity SAE 80W-90
I've seen different gear oils and some indicate they're for limited-slip differentials while others say nothing about this. I picked up this Lucas heavy-duty 80W-90 gear oil the other day but haven't used it yet. It meets the GL-5 spec part. What else do I need to consider ? Looking at the technical sheet - just now - I see that it exceeds "PG-2 Limited Slip" spec. A sales type sheet also says it's "designed for hypoid gears". Admittedly, when I was looking at it in the store, I only saw the "GL-2" spec part and felt it was proper oil. Reading other forums, watching videos, etc, others are using anything from Autozone-branded gear oil to basic Valvoline gear oil, etc. Seems like this Lucas stuff should be acceptable for this vehicle. Is that the case ?

Fellow G35x owner here. I've always done Mobil1 75w90 but your Lucas should be good as well. Dont forget the transfer case.

I don’t like Lucas but I’m sure it will be fine. Even super tech 80w90 would be good. I use ST all the time and zero issues

Yes, it's on my to-do list. What do you use, Matic-D or an ATF that meets the Matic-D spec ?

Matic D is really just normal Dextron that came out in like 1995ish. I ran Redline D4 my first drain and fill and then my second time i ran normal Castrol import ATF. A lot of Nissan/infinti forum guys like Redline fluids over X. If i can find them for reasonable price i would get it. Good thing about these cars are they not super picky on fluids.

I happen to have Castrol IMV ATF on hand too.

That's funny you say that because, just like with every automaker's vehicles, there are those who believe 100% without a doubt that if you use anything other than what the automaker says, your [insert part that requires lubrication] will fail. What is their response when that same part fails yet the owner used the actual spec'd fluid though ? Silence....
