From the conversation - his "opinions" as he referred to them
: (He said he was old enough to have some now)Any of their oils can be used as steam cylinder oil in non-condensing systems. Although the Sapon-Med types are far superior with rust inhibiting tallow, and run the 680 if your oiler will handle it, as it is the best and is intended for super heated systems.
None of the steam cylinder oils containing tallow should be used in a condensing system as animal fats are nearly impossible to remove from the condensate and will find their way back to the boiler. This includes either of the Sapon-Med oils they sell. He suggests using only the Pin Bearing and Journal oils, or "pure" oils for steam cylinder lubrication, as they can be fully separated from the water.
On whether or not to oil: He says on every engine there should be a means of administering oil to the engine, either hydrostatically or pumped. The decision on how much to oil whether continually or intermittently lies with the operator, and "the engine will let you know". All new engines should be supplied oil continually or at least frequently at first to prevent "gaulding" the cylinder(s). This allows the rings to seat properly and the cylinder to form a hard glaze, then oil admission can be tapered off if the operator wishes. However, there are still going to be instances where the engine needs a shot of oil. Essentially "If it's squeaking, it needs oil".
