Car is going in for a service on friday and I'm gonna get the diff oil changed while I'm at it.
MY mate gave me two different types of diff oil. He had an S2000 for a bit, so I get his left overs
Anyway, I have the 75W90ns and the regular 75W90

My car is a 2005 JDM S.
So which one do you all recommend I use?

thanks,

Oisin

 

Honda MTF. Job Done.

 

MTF?
The choices are REdline non slip (NS) or the regular.

 

Manual Transmision Fluid

 

NO NO NO dont put MTF in the rear diff its no good for it you need a oil that is designed for high pressure......Honda state a SAE 90 API classified oil E.G GL5 or GL6

XEP 80W/90 is a mineral oil based gear oil, that has been formulated with a high level of extreme pressure (EP) additives and friction modifiers to protect the critical mechanisms of limited slip differentials. In addition to high load carrying capability, XEP 90 will protect against rust and corrosion and has a low foaming tendency. Shock loading occurs when one of the driven wheels looses traction and the differential locks redistributing the drive equally. Standard API GL5 gear oils are unable to cope with this extreme condition and therefore it necessary to use a proper limited slip differential oil to promote long component life.

XEP 90 has been specifically designed for use in limited slip differentials requiring a SAE 90 lubricant. This includes all automotive, agricultural and heavy duty plant designs. This grade may also be used in standard differentials, axles, reduction hubs, slewing gears, transfer boxes, etc., where an API GL5 SAE 90 gear oil is required.

Paul, how much did that stuff cost you? And where'd u get it? Thinking about getting Shane to do mine...... any noticeable difference in the gearshift? Ta in advance.

 

Use what the book tells you to use.

 

You can go to Opie oils web site and type in you cars spec; ie, Honda S2000 and thier magical computer brain will tell you what options are available.

I have just taken delivery of fluids from Opie after doing this and also speaking to 2 of the people there who recommended the following :-

________________________________
Thanks for the mail.

Plenty of choice for the engine, 10w-30 is just one of the recomended grades. In the UK we tend to recomend 5w-30 or 5w-40 synthetic. If you want the best then the Motul 300v or the Silkolene Pro S are it as these are ester based.

The Motul Gear300 will be fine in the diff despite it not being lsd approved, over it I tend to suggest the SIlkolene Syn5 75w-90 as this is lsd ready.

For the gearbox you will need an MTF, Motul dont have much int he way of these. I would look at the Amsoil Synthetic MTF or the Redline MTL, both very good synthetic MTF oils.

Cheers

Opie also deliver fast; I'll be buying all fluids from there from now on

 

Read the FAQ, and see what the rating the oil you have has got.

Simple.
