I installed mine must have been 4-6 years ago (cant really remember its been so long) with just normal diff oil and its been wicked, never had to touch it since.

Ah Mike
We all know the truth to your 6 years is that you hardly ever drive your Surf, and F-all offroad, hence why it hasn't worn out!
I have done shit loads with mine (front end but always driving) and use REDLINE Shockproof oil. Available from BNT. Tis thinner and therefore less drag, yet has a wider viscosity range and is fully synthetic.

X2, just normal diff oil, mine works great, can't even hear it on-road.

All the comments on the US forums are to use 90w 140 to improve manners and reduce clunking and banging

Super cheap have it, Nulon brand.

i used the normal spec lsd oil, only because i had some. no need for thicker oil unless your giving the diff a really hard time.
