Interesting. The only steam lubrication I have learned of is the labyrinth seal. No idea how this would apply to reciprocating machinery. A Google this morning I see that some vertical steam engines were operated without oil lubrication, relying on the 'accidental' condensate to provide cylinder/piston lubrication. In real life would a cooler than possible cylinder not reduce the efficiency? I also read (I suppose not surprising) that the oil technology could rely on there being some condensate present with it.
