Of course one should use steam-oil. But if you are temporarily out of it, using normal car crancase oil is ok, until you get the right stuff. Even Aster wrote so in their instructionsfor my P8 / BR38. ( I would go for mineral, but seriously, probably even cooking oil or whatever, would do.)

Aso the water has a lubricating effect. Though running a completetly new engine without oil, is a bad idea, in my opinion.

Also, running on air for any extended time, without oil, makes me uneasy. During assembly, one normally puts some oil in the cylinders, so a bit of testrunning on dry air, is ok.
