Its like if you take some mothers aluminum polish and rub it on a piece of aluminum that is raw your white rag will be black,but if you do the same thing on a coated or treated piece your rag will be clean.
My shock has a modified 2 stage valve stack and proper spring also so the fact that it is working more efficiently may also contribute to the oil breakdown.
Got it - makes sense . . . . . .thanks!
