So I did the diff/ gear oil change last week and noticed a bit of slug and gunk on the drain plug.

I changed it w/ the valvoline 75w-90 hypoid gear oil, but plan t change it soon again maybe next oil change sinve I want it to clear out completely of any contaminants in there.

I plan to use redline fluid but on their site they have two types


75W-90

and a 75w-90 "NS" version


ist his NS version ok to use or only the first one?

Also,

***What is the best fluid that most of you expereneced S owners have been used or recommend?***


TIA

i just did this today. i changed it with redline 75w-90

 

This is a great oil, I have used it my last 3 changes. It is the only one that comes out looking and smelling like it did when it went in. It's so pretty and red and smells like love being made.

 

I used this but likes LE better. Try it, you will like it.

 

So far I like the Redline MTL 70W80 Synthetic I put in my transmission the other day. If it outlasts HMTF I will prolly give Redline diff oil a try. Hell, I may become a Redline fanboy. I am currently a LE fanboy but they don't have a transmission oil for us. That I know about. If they did I bet it would be red and pretty and smell like love being made.

 

I'm really liking the Amsoil severe gear 75w-90, best stuff I have tried so far.
