can i mix dot 3 and dot 4 brake fluids for my clutch?

[sephrothm2]

I need to fill my clutch fluid and I don't remember if I've used dot 3 or 4 before. Am I able to mix brake fluids dot 3 and 4 for the clutch? or will that destroy stuff?

3 n 4 are ok. def not dot 5 with either

[godrifttoday]

But u generally want the same fluid... But definitely not dot 5 . Like mention above

use DOT 3 in the FSM

DOT 3, 4, and 5.1 are basically the same and differ only in boiling point. If you manage to boil your clutch fluid, you've got bigger problems. Who cares what the FSM says, just use whatever.

DOT 5 have silicon in it(like some boobs too) and is not compatible with DOT 3 or 4.

You just wanted to say "boobs" didn't you? DOT 5.1 is fine though, it's polyglycol based like 3 and 4.
