Haven't posted in a long time, but these oil threads just suck me in.
Friction modifiers are a class of additives that include both friction reducers and friction adders. With oil bath clutches, the type of additive we are worried about is the friction reducer and its potentially degrading effect on the clutch. Typically, these take the form of a grease, they have a polar head that adhears to metal or fiber, with a long organic chain that trails out behind. The long organic chain helps to hold oil in close the surface of the metal and decrease the observed coefficient of friction. There are many other type of friction modifiers, but I think these are the ones most likely to cause clutch trouble. I hope this description was clear.
In the past several months there have been two very informative articles about oil in MCN written by the same guy who wrote that first article.
