R32 Clutch Master Cylinder Fluid

[sam'sR32]

Hello all, this is my first post to these forums. I got a used R32 shipped from Japan to South Korea and was going through the car and noticed that the clutch master clyinder fluid is black. So at a minimum I need to flush the clutch system, if not get new parts. My question is what kind of fluid do I use? The cap on the master cylinder does not specify, and the PDF Skyline manual I have does not specify. Normally in other vehicles I have worked on, the hydraulic clutch used the same thing the master cylinder does (in this case DOT 3 specifications, pick your brand). Just making sure Nissan did not switch that up on the R32. Thanks for the responses.

brake fluid.

there's this thing with the skylines that i've seen. since people never change the fluid, it's like the cylinder itself has gone black. like even if you change it, it might still look black.
