What fluid? Dampening of that arm is basically determined by its construction (choice of arm material and design) with some adjustment made by altering the space between the magnets that hold the string "bearing" taut.
I would never put anything on the string unless this is either recommended or green lighted by the manufacturer. You could cause the string to weaken, to stretch or maybe shrink -- who knows?
