i have searched but not found the answer i want. i have been hearin a lot about it and heard its ok to use it even though it is 15w 50, just as long as its not the new stuff. how will i no if its the new stuff?

ithe new stuff is in the fancy bottle...i have looked everywhere for the old stuff but its no where around here.

i just use the gold cap 15w-50 now in my engine side on my 450r, you have a 400ex so I dont know if you should use it b/c it might be bad for your clutch
