Clutch Fluids are compatible????
I was searching the archives for what fluid to use for my ZF clutch and I'm a little confused.
I know you CANNOT mix silicone (Dot5?) with Dot3 in your brake system, but I hear people going with Valvoline Synpower Dot4 instead of the Dot 3 it says on our clutch master cylinder covers.
The Dot4 stuff is synthetic, but it isn't silicone is it?
Can you mix Dot4 synthetic with Dot3?

Valvoline synpower is not silicone and it is both DOT 3 AND DOT4.
You can mix it with DOT 3 if that is what is in your system. But if what is in your system is old and dirty you should replace it.

I am going to flush the whole system anyway.
