Anybody have any reccomendations? I just got the Nismo LSD Pro installed and going through the break in procedures. It says to change the diff fluid after breaking it in, not a bad idea considering what I'm going to be doing to it soon.

So...any retailers out there sell the Nismo 80/90 fluid it comes with? Or have something better? I'm looking to purchase some asap.

 

royal purple is available at pepboys, arguably the best one of the best fluids out there!

 

I know Mobil 1 synthetic 75w90 is available @ Auto Zone & Advanced Auto. I'm using that w/ the GM limited slip additive next week when I do the diff. oil change. Was going to use Redline SuperLite Shockproof w/ the GM additive, but hard to find around here. Several Z-fellas recommended the Mobil 1 w/ the GM additive - good combo in their opinion. Since I only have the stock Z LSD, it should be sufficient.

 

Where do you get this GM additive? What's it' about?
Thanks.

 

The additive is just a little extra insurance for the rearend - helps reduce chatter and noise, reduces plate friction. A similar type additive comes in most Redline gear oils. The GM version can be purchased at most GM dealerships ($6-7). Part #1052358. Is it neccessary on a stock LSD? - No Is it cheap insurance for peace of mind? Yes Kinda like me doing an alignment check at every other oil change...neccessary - maybe not for peace of mind after buying $1000 tires - yes!

Just my opinion.....

 

I could shipp you redline form NJ but you are probably better off just going to redline's website and finding a local dealer. If you can't them PM me and I'll get you some..

im gonan go with the royal purple 80/90... is it ok if i add the GM stuff even after a couple days of changing the diff oil?

alos how many quarts of either one did you use?

 

Uses almost 2 qts. of oil (about 1 3/4)......and yes, you can add the additive afterwards, tho I've always added it at the time of change in my cars

 

We use Mobil1 75-90 syn in our GAC cars.

 

i did it tonight. went to pep boys, they didnt carry royal purple. so i got the mobil 1 75-90. extremely easy to do. the noise that i had went away also so thats good. the old oil was BLACK and very chunky-like aroudn the drain plug. also it didnt look like there was alot int here to begin with.

how often are you guys gonna change the diff oil?
