[fokky]

So I am aware of what they all are and what they do.

QUESTION;How do I tell if I have DOT 3,4 ,5.1 or DOT 5 in a second hand bike.
I know what it should have but not whats there.
Is there a simple test...like 2stroke petrol on paper type thing.taste?thanks

Chuck it out,start again with the correct fresh dot rateing.:yes:

Pour some into some water.

If it's DOT5 it won't mix.
