But if I were restoring a $25,000 machine, spending $250 on 10 grams of Braycote wouldn't seem outrageous. Sure it's more expensive the going to the Texico station for a can of motor oil, but it's also not going to eat through the decaying rubber belts within a few years. > > I'm very careful with PTFE-enhanced lubricants, such as TriFlow--they > tend, for me, at least, to get gummy. Braycote isn't a PTFE-enhanced petroleum based lubricant. Those have all the disadvantages of the base lubricant (which can evaporate or change chemically), but with added PTFE. > A good petroleum oil should last > decades in this particular application. Probably. You just shouldn't get it (or its evaporation or decomposition products) on anything that that might react badly to them or get too warm.
