Good knowledge there, thanks.

Baldy

so where can we get those testing strips for the home mechanic?

They still didn't correlate the black tint & black sludge to anything specific.

I read somewhere (before the internet) that it was worn off rubber from the piston cups.



They did imply that if the fluid starts to turn dark, flush it.



Good info.
