as im about to pull out the gearbox in my car to replace the clutch and do the rear main, what replacement oil should i use in the gearbox? i remember someone somewhere once said there is a specific oil to use with the Ralliart LSD's, or any LSD for that matter.

any direction would be appreciated

:D

I used some Motul gear oil. Can't think of what its called but was about $45/L.

I think Disciple might have put the same **** in his Ralliart and was happy with it.... or I could be wrong.

Edit - think it might be called "Motul FF 75w90"

Does the box still shift fine, or is it a bit crunchy?

I've heard that Redline is a good oil, as is Penrite's gear oil.

Mine? Shifts are as smooth as silk. Admittedly I only ran it for about 4,000kms.

Make sure u use the rear main thats brown plastic and genuine.. dont use the mits metal one..


Oil is Castrol VMX90.. good stuff..:)

Penrite FTW

i just replaced mine with Motul FF LSD 75w90 i think... (see disciples service time thread)

I have a shortshifer (thanks DaJaJa) in my car at present and shifts are nice and smooth.

Motul FF LSD mate.

thanky you, will get some on friday

Make sure whatever oil you use that it is a GL4 oil NOT a GL5.

GL5 oils are known to attack/react with certain metals within manual magna gearboxes hence why MMAL specify a GL4 oil. (Even my mazda 3MPS must use a GL4 oil due to material used inside the gearbox, and it also comes from factory with a Quaife LSD fitted)

Having said that i just use castrol VMX-M oil in my ralliart LSD equipped gearbox (VMX-M is very similar to VMX80, only real difference is that its MMAL approved for factory fill) and ive never had any shift/diff problems in over 7years. Its pretty cheap too so ya can afford to change it every couple of years. Costs me $25 for 4litres (our manual gearboxes require 2.8Litres)

whats the difference between the 2?
One is metal and leak after a week and the other is plactic and good..:)
