I know I saw it somewhwere here but cant find it know, but I was wondering the best way to change the oil in my ROCO WC.I have an IH SUNDAY and need faster rebound so I am putting in 2.5 and like water,I think about 3 to 1.I am getting oil wed night and am leaving for the open thurs so I have 1 shot, or the 5th will have to back on.Thanks DH9
