Where To Get Oil For Diff

Recommended Posts

Hey everyone

I have got a 2way Cusco diff and would like to buy some oil. On their website they say use an oil with a viscosity of 80w-140.

I rung up the local workshops(Xspeed, Intune, cypher industries, Nissan).

Xspeed said they will ring me back, cypher industries said they have redline oil however they recommend to use a 75w-90 because 80w-140 is to thick.

Intune and Nissan both just dont stock any of those oils, Nissan dosnt stock Nismo oil either.

So i just wanted to know what viscosity should i stick to? 80w-140 or as recommended by the workshops 75w-90? The car is going to be used on the track and also as a daily.

Finally does anyone know who in Perth holds redline, motul or nismo oil to buy?

Cheers guys, ni

Either 75/90 or 85/140 will be OK. Make sure it is a LSD oil. I believe most aftermarket diffs require a mineral oil, I know Kazz recomend mineral and say to avoid synthetics.

What does the Cusco instructions say?

Hey guys

I think ive found the oil i am after which is the Motul 90PA Differential Oil..

Was reading a few threads on forums that had people talking about the Cusco 2ways and they found the Motul 90PA Differential Oil to be the best solution. It's a mineral based oil also..

Has any one else used this on there diff, if so how would you rate it?

thanks for all the help :D

No problem if you don't mind the extra wear and noise
I use Castrol saf xa 75w90 in my cusco 2 way.

Drives mint.

Can get it from most auto shops

Hey guys

Hmm i have no idea now which oil to choose. i say this because im getting a 50/50 opinion where some people state that the75w-90 is the best option, then other people say use a thicker oil such as a 80w-140.

cypher industries said that the 80w-140 will be to thick for a car that is also used on the road and that when i come into tight turns it may be to tight, hence why Zac said to go a thinner oil such as the 75w-90..

But then in the cusco website they state a 80w-140, so all in all im more confused about what oil to get then i was before.

I looked at the Motul range (as ive heard they work great with the 2ways) however the Motul 90PA is the only one which is mineral based. the 75-140 oils are all fully synthetic.

Hey Steve

I am leaning towards the 80-140, 85-140 viscosity

Using an oil with such an viscosity in your diff have you found any problems when coming into tight corners or round about?

Hi Ni,

Now you are coming to what can be a frustrating but also rewarding part if owning a performance car

i.e. Knowing what suits your purpose best.

Best option IMO is do some r&d yourself - diff oil isn't too expensive, so try the 90 weight Motul, see what

you think, then try the 140 weight and do the same - that way you will know what is best for YOU

and don't be scared of synthetic oils, synthetics count amongst some of the best in the world, also, not all oils are created equal, some 140 weight oils will give alot better results than others (I have used both valvoline and a

couple of different castrols) I have also used 90 weight, but changed it

out about 2 days later cos I didn't like it

as for roundabouts/tight corners, you will most likely find the diff will lock and the tyrese chirp, or if you are just rolling around, the diff may clunk a little (I have found this is worse with lighter oil than heavier, the heavier oil quirtens down the diff - on the ones I have used anyway)

FFS its all the same! dosen't matter what brand, make sure its mineral and is suitable for LSD. Then chose your viscosity! All the viscosites mentioned in the above posts will be OK.

For gear oils most oil companys use the similar additive packs and the base oils usually come from the majors ie Mobil, Shell, BP. So any reputable brand will be fine. Dont get carried away with brand names, do you really think so called specialists like Motul, Redline, Royal Purple invest more money into research than regulars Mobil, Shell, Castrol and so on? I dont think so!

no. i never said anything about a brand name however i read reviews and most guys on forums such as Skyaus, Hardtuned post good reviews

on the motul range, HENCE why i asked about it! not because i like the name nor care. i will go for a Mineral based oil as stated.

thanks, ni

Hey everyone

Alright guys I’m going to try two oils out.. Firstly i went for the Motul P90A because 1) there’s been positive feedback saying they are great in the Cusco 2ways and quieten them down without it slipping. 2) The original owner of the diff said he used the Kaaz 2way oil which is a 80w-90.

i will run the motul oil first, if it seems to be an issue i will change over to the higher viscosity Castrol LSX 85W 140 and try that as Steve stated.

Thanks for all your input guys

Ni

    • Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
    • Centre-offset muffler under the floor, same as stock. Just....3.5". The change from straight pipe there to centre-offset will mean that you need to remake some of the pipe (add a bend or two).
    • Hey guys. So my R34 GTT has a custom 3.5” exhaust (done by previous owner) with a high flowing cat, and then just a Varex cannon muffler on the back. The car does drone alot and is really loud even on highway driving just cruising, as you can imagine due to the Varex muffler basically being a straight through with the valve open. As much as i love a loud RB, it can be a bit much with no other muffling in line and just driving casually. I wanted to lower the volume output on the exhaust a bit, as well as remove the drone (probably a way to do both at once), and was going to do it all myself as I am a fabricator and have done exhaust work in the past, so the fab work isnt my issue, im just not sure on the right product or type of product to use to get the job done, and i doubt an exhaust shop would be wanting to help me as they wont be making any money from helping me, unless they supplied the product? Anyway any help or guidance in best way to approach this would be awesome   Thanks in advance
    • Meh, whilst the Honda is a "really" good car and has potential if you want to drop coin on, it was uninspiring for me to look at, but, it did serve its purpose and is now in the boys hands, his happy, his girl is happy, as she wasn't to keen on the noisy old Patrol, and most importantly, the Minister for War and Finances is extremely happy that her "little baby boy" (6'2 nugget who is currently training to be a copper, which will make 3 coppers in the immediate "circle of trust") has a well sorted reliable car that doesn't guzzle diesel Me, I'm more than happy with the NC MX5 that I replaced it with, it's a fun little car that I like looking at, like driving, and yes..... I do like the fact that the maintenance and modifications that I have done/will do are plentiful and relatively cheap, well........ while staying naturally aspirated slow that is, and that's all I really need for a fun little daily, I can rev the 5hit out of it rowing through the gears and never really break the speed limit  In saying that wicked word, "modifications", I've already ordered something for some noise and an additional "3 ish" horse powers, or whatever it gives, in the form of a header, and, a new set of "cheapo" BC coilovers that are already sitting in the shed waiting to get put in, I had the same BC's in my old NB and found they were fine for the street, hwy, and the occasional track days I did in it, they have 6kg front and 4kg rear springs which is about 10% stiffer than the stock springs which I found worked well for their price  I've also already been in touch with MX5 Mania in Dural, so once the header is on it will get a ECUTek RaceROM tune there (I cannot rev match for 5hit, and I loved the RaceROM rev match and FFS in my old 86 "RIP") In other, maintenance news, I put some new sparkler plugs in it, and have a new set of DBA Street series pads to put in over the next day or so, I'm running the DBA street series in the SS and Honda and really like them, they work great and are not dusty at all I've also booked in a few days leave over this weekend to give me 4 days weekend do some paint correction and give the leather seats some conditioning and interior some Bissell and steam cleaning OCD lovin', the carpet and interior looks clean, but from my experience with the Bissell IRT carpet, and the steam cleaner IRT trim, looks can be deceiving I've also found that finding a detachable hard top is proving problematic, the main reason why I didn't like the NC initially was the power retractable hard top that I seen them with gave the roof line a weird look, the detachable roof though looks good, and is a same shape as a NA/NB hard top, similar, but unfortunately not the same as it has different fixture point on the front, so fitting a easy to get NA/NB detachable hard top is no bueno New Old cars are fun, cleaning, hunting and playing around brings much joy How are your beasties going? Do you still have the Skyline with the LS???, or Barra??? that you were playing with
