Looking to get into doing my own changes and save money.
read a few threads about what oil people have used with no real answer on which are the best.

better to run 75w-140 or 80w90? im not looking to be cheap either ill get whatever is best for my baby ha

I just did this a week ago, from what I got from reading everything:

80w90 Front

75w140 Rear

Or you can do 75w140 in both, which is the route I went.

The 140 is just a thicker oil, which isn't necessary for the front since it is not getting as much strain as the rear.

thinking im gonna go with Royal purple 75w140 in both. noticed a slight leak on the front pinion seal I believe after inspecting it right now.. was near the drain plug though but its tight

That's exactly what I went with, I am a big fan of royal purple. I use it for my engine oil too

Paskell, you may want to run the lighter gear oil in the front as recommended, since you're in BC. Low temp viscosity will be higher than recommended. It may cut gas mileage a bit, too, since the front is always spinning.

Royal Purple is good stuff. I run Red Line in mine (seems favored by BMW CCA tech advisors - I've been a long time member), and it's about the same price, or just a bit cheaper than Royal Purple from a quick look.

Cheers!

ah yeah you make a good point there may have to go 80w90 in the front. thanks for that

 

[Paskell]

much difference in 80w90 vs 75w-90 my local pace doesn't have 80w90..

 

[dreep]

Not too much. FWIW, Red Line's application guide lists 75W-90 for the front diff. With a full synthetic, you will have good shear strength. Cheers!

 

[Paskell]

gonna go all royal purple. 75W-90 and 75w-140
thanks for info

I run 75w-140 in both. Have for over 6 years since my first front diff crapped out on me in 2010.

I was using Amsoil Severe gear synthetic in the rear, but since installing the Spartan Locker I`ve switched to Lucas 85w140

 

[Paskell]

Went pretty smooth today. Rear diff fill plug was pretty tight though. Snapped a wratchet had to used a breaker bar. Filling the front diff is a pain. As I could not find a pump.. and my front pinion seal is for sure leaking..

Dont forget transfer case too. Here's a vid for anyone reading who wants to know how to do it. Dealer wanted $140 for this.

 

[dreep]

Good point^^^. I use Red Line Synthetic D4 ATF in the transfer case - cross references to NissanMatic D, J & K. While I'm thinking about it, Red Line cross references their D6 ATF to NissanMatic S. Not sure if RoyalPurple cross references for transfer case, Paskell.

Thanks for the video. Got the Royal purple Atf is is good for Magic -D , J , K
