I am getting my clutch done on Friday and am putting in Redline gear oil at the same time. On their website I came across two products that seem to be what I need and Im not sure which to go for. the descriptions were as follows:

75W90 GEAR OIL - recommended for most street driven and racing differentials. Excellent performance in conventional and limited-slip units. Also for limited-slip manual transaxles which require a 90 WT oil. Contains limited-slip friction modifiers.

MT-90 Manual Transmission Lubricant
a 75W90 GL-4 gear oil designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

and then there was a second weight of the MT oil:
MTLŽ Manual Transmission Lubricant
a 70W80 GL-4 gear oil (SAE 5W30/10W30 engine oil viscosity) designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

I am unsure of which one to get because I do have the LSD, but I remember hearing that the regular 75/90 gear oil was not to be used and that I should only get the MT-90, but that was in response to someone without the LSD I belive.
any help would be appreciated.

 

of the 5-speed guys that I am aware of who use Redline prefer the MT-90.....

BUT, those are 4th gen guys who do not have LSDs......

Hopefully, Jeff92se will be able to help on this one.

Also, you might want to try the 3rd Generation forum here....

 

Hey Johnymax,
I use MT-90 in my tranny and you know I have the same trans)(LSD) as you. I had it rebuilt about a year ago and the people who did it said the only thing that should go in there is MT-90.....
See you at the meet unlees they make me work Sat. but I get off at 1 so I could prob. be there by 4.

 

Cause thats what I bought today.

I am also gonna have them shave the flywheel down a bit, but I need to know the specs to tell them for turning the flywheel. do you have any Idea what I should tell them for that? they said that they could get aggressive and leave it on the turning machine longer to get more weight off, but if they leave it too long thenthere will be a problem with the springs hitting the bolts? you have any Idea what #'s I should give them?

 

Of all the stories I have heard, anyone who resurfaced thier flywheels have had problems.

Why don't you go with an aluminium flywheel insert. I can't remember for the life of me where I saw one, but I did see a guy with a Max who put one in.

 

supposed to be balances and resurfaced when you replace the clutch?
From what I understand they are just talking about leaving it on the machine doing the resurfacing in order to shave off more of the metal, they just need numbers from me so that they dont take it too far!

 

My intent here is not to promote another car club, but to provide an avenue for more info. The Internet Z Car Club (www.zhome.com) has had many discussions on oils. I would also say very deep discussion. We have had engineers on our mailing list provide and discuss the properties of various oils based on tests. Redline oil (for xmn and diff) is highly respected in this club. You might check out this site to find something useful. You may also contact people, like the club president, for further information. The club has some extremely informed members. And since this club promotes another Datsun/Nissan car I didn't think it would hurt the Maxima club to mention it here. Take care.

 

Johnny, check your mail. Yes, after the flywheel is lightened, it MUST be resurfaced and re-balanced. Take the pressure plate down with you also if you can. That thing is heavy!

 

thanks a bunch Jeff!
Ill be seeing what they can do for me
