What kind of clutch oil should I use?

sherco trial 300 2016.

Do I have to use mineral oil?

I know the mineral oil cap is green.

But, The cluch cap is black, can I use brake oil?

 

Manual Says DOT 4 (they prefer Minerva as vendor, but does not matter)

Thank you, but what I'm asking is clutch oil.

You mean gearbox oil (which is shared by the clutch as well).  I use 450ml of ATF in my 2016  250 Sherco.  

 

In fact it is not the cap that is green. The rubber under the cap that is green when mineral oil is used. (Mostly)

You can double check with a drop in water:

1 dot oil mix well with water and turn white.

2 mineral oil floats
