I bought some Silkolene Pro RSF 7,5 WT to replace the oil in my 2007 66 RC2x. Looking on the cSt values for the oils it appears like the stock oil is 26.1 cSt and the Silkolene is 37.19 cSt. I understand that this will affect the suspension, but how much? Will it be totally crap? I read that older Marzocchis works better with thicker oil than stock, can anyone confirm this? I'm selling the fork, but I want to change oil on it first as it haven't been done in a couple of years (still works goood though!). Viscosity Index is 150 for the stock oil and 322 for the Silkolene, I guess that's good??
What about using the same oil in a Fox DHX 4.0 2010? I tried to find some numbers on the stock oil used, but couldn't find it.
