which lsd oil?

[gotrice240sx]

i have a nismo lsd which gear oil are ppl putting in? :fruit:

[thelinja]

I used Valvoline 80w-90 for my HLSD. I'm assuming you have a clutch type diff. I'd use Redline 75w-90 on it. It already has LSD additive added to it.

[Flybert]

Mobile 1 if you are looking for a fully synthetic gear oil.

[Dousan_PG]

85w140 Redline (i think that's what it is)
but thats beacuse of heavy track use and abuse :) HEHE

75w90 is great for moderate use and daily drive.

i prefer Redline.

[gotrice240sx]

ok i just put in some moble 1 75w-90 full synthetic and now it clunks alot? it never relly clunk when i had the nismo oil in any thoughs? cant fine anyone who carries nismo oil eather

[adey]

Synthetic oil, I've heard, will make it clunk more than if you use dino oil. I don't think it's something to worry about too much... try to get ahold of some friction modifier (mopar makes it, if you go to a chrysler dealer) -- that'll help w/ the clunking at least a little bit.

Otherwise, you can switch to syn blend or pure dino oil to decrease clunking if the rest of your diff is in good health (i.e. you don't need the synthetic protection to keep your final drive from exploding).

Also, just an FYI - I'd use some thicker stuff, preferrably 90W140 or similar, since the diff, even under daily driving, will see quite a bit of abuse. Don't forget to change the oil out w/ every oil change, too! (supposedly every 3000km, but so far no problems doing it every 3000mi for me).

Good luck!

edit: ha ha, I just noticed the original question. I run valvoline 90W-140 on my nismo/tomei (not sure which!)

[RBS14]

i'm running redline 75w90ns........ the ns stands for no slip. supposedly for "race differentials". any pros or cons regarding this variant of oil?

I'm definately putting in 75w140 tho next time for the added protection.

[gotrice240sx]

what about the diff oil that pdm sells called motul? anyone used that?

[gotrice240sx]

which oil do ppl use and what kind of lsd do u have thanks

[Flybert]

I broke my Tomei diff in with valvoline semisynthetic and the knocking wasn't too bad. I then changed it to the Tomei oil and the knocking was worse for about a week but it's slowly going away. It still clunks on tight turns but not to the degree it did before. Next time, I'm going to try the mobile 1 and then that Redline oil dousan is using. It's best to experiment to find out what you like. Use the Mobile 1 for now and switch to something else later. It couldn't hurt if you stick to synthetics. The cool thing about mobile 1 is that you can get it at any local auto store too.

[pearlwhiteS14]

what kind of oil for a stock lsd for an s14?

[Dousan_PG]

any gear oil does the job pearlwhite
just get a 75w90
vlsd doesnt matter
you can use cooking oil if you want hahaha (dont try that please)
just get whatever
you dont need any lsd additive either

I think you should stay away from the synthetics if you have a Tomei diff.

[MrMigs]

I have a Nismo LSD, and I just use 85w-140 from Kragen. Seems to be working great.

[Flybert]

Maybe you should back up what you're saying so that there is some credibility to your random comment. Seriously.

[Dousan_PG]

no he's right
KAAZ suggests NOT to use synthetic oil
call them. ray has posted about it on zilvia maybe. i forget

remember
kaaz=tomei

call kaaz and verify. they got a enw site too hehe

[tsunami0ne]

BTW, YOU'RE WELCOME :hsdance:

Such gratefulness for such an important piece of information.

No, I'm grateful and glad you brought it up but I would like some backup to it especially since there is so much misinformation out there. From your original post it didn't sound like you knew for sure about that info. Thanks though. Seriously. I will definitely stay away from the synthetics.

Dousan: Who's Ray?

he's right
CALL KAAZ
one dood on 240sx forum called Kaaz to verify.
he had a t-trax as well (i had questioned the syn thing as well)


this guy isnt bs'ing you. before you try and call him out on it, do some research and THEN come back so you wont look like a fool.

I just wanted him to backup what he was saying instead of just saying "I think you should stay away..." It didn't sound like he knew for sure and I wanted to know for sure. That's all.

Plus I was misled by Sam in a way. He told me that using Mobile 1 would be an acceptable alternative to using the Tomei oil so I just assumed he was right. I just think that you guys misunderstood what I meant. I wasn't claiming he was wrong or anything like that. Just wanted to know for sure. I am really glad he posted that.

[Flybert]

Dousan, you reply too damn quickly. You're response was to my post before I edited it. I guess I'm just coming off like an ass today. Didn't mean it at all.

[tsunami0ne]

Dousan: Who's Ray?

The reason I didn't feel like backing up my statement is because it would have sounded something like this:

Don't use synthetics because Ray and Sajeet at Kaaz USA told me so and they are always right. When I asked them why, they said "because Kaaz Japan told us so."

That statement doesn't give any technical reasons as to why you shouldn't use synthetics in your diff. It's really just me parroting information.

No hard feelings.

[Flybert]

No hard feelings.

None taken and thanks for the info.

That dood was me... Im going to try Motul 90 PA. Its a mineral based oil made specificly for clutch type LSD units.

[kazuo]

Hey all,

I have some MOTUL oil I got for my Factory VLSD that Im gonna use... my friend mentioned to me before I refill it I should get some sort of additive fluid for it.

He said that Chevy dealers sell the stuff cus they use it in Camaros and whatnot. Said its for silicon pack something or other... I dunno. I just installed my VLSD (despite that Iv'e had it for like a year and half... damn axles) soI dont know too much about it.

Anyone know anything? A couple of people told me to forget about the additive and just refill it :)

Thanks

you do NOT need additive for VLSD
your just wasting your money
the VLSD area is separate from the fluid, its in its own packet or something, special fluid. you are just putting fluid for the gears inside (final gear and such)

you just need regular good ol diff fluid. nothing special at all.

[kazuo]

Thank you Aaron SPL.

:D

Is there any way to replace that special fluid thats in the packs? Or it basically lasts for the life of the differential?

Thanks bruh

[Dousan_PG]

i think its for the life of diff
no way to fix/replace. but should last forever

[initial_24d]

dousan is right, the gear oil never actually gets into the VLSD mechanism be cuz the mechanism is made of a viscous silicon based fluid( i believe) which is sealed to the out side gear oil, and in turn the viscous fluid lubricates and locks the diff, the only way to replace the viscous fluid is to have the VLSD overhualed and rebuilt. from what i have heard it costs a sh*t load and isnt worth it when you can just go out and get a whole pumpkin for like 160 to 200 or so. I know kaaz probably wouldnt want to recomend any specific gear oil other than their own but has anyone asked them?

[four]

Kaaz recommends you to use any generic gl-5 based non-synthetic gear oil for the break in period. however, after break in, they recommend you to use their gear oil

Hi Four,
We do recommend our own oil because it is really a high grade pure
non-synthetic type oil. I know it's kind of expensive. But you can use any brand petroleum based oil as long as it is GL5 spec 80w90. You can also
put additive too like from Ford dealership. I have tried many different
brand oil on my own car. Some brand will cause more chatter than the other
but it won't hurt the unit. The more frequent you change the oil the
more life you get out of the unit. BTW my AE86 unit has 82K miles and
still works great.
Kaaz engineers do not recomment synthetic type oil because it creates
a film between the clutch plates and normally will cause more chatter.
They told me that this film will prevent the clutch to slip and grab
smoothly. Becomes more abrupt so it causes more chattering noise.
For more questions, please email us at [email protected] or
call us at 888-522-KAAZ(5229).

hi ray, how much of this info would apply w/ a NISMO Unit? is it possible you could find out? i forget what my NISMO oil was when i bought my LSD.

thanks! :)

Hi Dousan_PG,
The Nismo oil is synthetic type. I have openned a Nismo 350z unit the other
day and found out the plate design is very similar to Kaaz. Which means you can restack the plates to get different locking rate. The ramp angle was slightly milder than Kaaz. I don't know if the clutch plate material is same or
not but the groove design was similar. Therefore, if some nismo owner is experiencing severe chatter problem, maybe switching oil type may help.
But one Kaaz engineer told me that once you use a synthetic type, you need
to disassemble and clean the unit to get rid of the film from the plates.
For just viewing purpose, I have attached some photos or Nismo and Kaaz
350z unit apart.
Regards,
Ray

[Dousan_PG]

great thanks
yeah i have the adjustable NISMO lsd..NIsmo SSS (before the GT PRO came out)

i have pretty much no chatter but i also run a stock clutch (240sx) and its at full lock (100%) setting on the LSD (of 3 adjustable settings) so there isnt much noise beside tire chirp.

i dont run any LSD additive just straight REDLINE oil.

thanks for the info AND pictures, great appreciated!
also the pics..it looks as though the NISMO unit is on the right, correct? (looking at last pic)

[kaazlsd]

Oops! Forgot to add the photo of the Kaaz gears inside the 350Z unit.

[Flybert]

Hi Dousan_PG,
But one Kaaz engineer told me that once you use a synthetic type, you need
to disassemble and clean the unit to get rid of the film from the plates.

I broke mine in with a semi-synthetic and then switched the tomei oil a couple days later. Mine grabs just fine. Maybe since it wasn't fully synthetic, I'll be OK.

[addicted2sp33d]

I've been running 15W40 Dino Oil in the engine, Valvoline 95W140 in my tranny, and Redline straight 140 in my diff (heavy track abuse), and everything runs smooth as can be.

But my experiences might be a bit different, since I'm running a mechanical Torsen diff (Road-racing, not drifting), rather than a locker or VLSD. :rawk:

Hi Dousan_PG,
The Nismo unit is at the bottom on the first picture. Kaaz unit is on the
right in the last picture. On the clutch plate photo, the one with more
friction surface and less teeth is Kaaz.

[kaazlsd]

Hi Dousan_PG,
Also Kaaz has 24 plates and Nismo has 20 plates on the Z unit.

*resurrecting an old thread*


So I've been thinking lately, "gosh.. a new bumper and a paint job would be fresh!" But realistically though.. a LSD would be so much better. Anyhow, I've been debating on what I should get. I'm stuck between choosing on a new LSD or a crackerjack one. I can't decide, I would really like new a Tomei or KAAZ, Kenji from GSpeed says he could install a new Tomei for me. Or I could go with a crackerjack LSD and buy a used pumpkin from him and pray it's a good one. anyhow, how did you guys choose?

and anther thing, I was talking to this guy and he told me he changed his LSD fluid every 3000 miles. I think that's a lot of oil to change, but I'm a newb. So enlighten me, is it necessary to change it that often?

[myleftlung]

W/the talk of clutch diffs and synthetic oil's not going hand in hand, would this be the incorrect oil for my KAAZ 2-way? I poured that stuff in, but my car's just been sitting. A little worried now. :(
