Right, what you say of course makes perfect sense to me. There was, however, no "golden" oil on the stick at any point. I haven't changed it yet, and it hasn't actually been driven on the road like that. Only thing I did with the extant oil was a simple finger viscosity test. This whole project has grown for me; originally the goal was simply to get the thing running and driving to at least a minimal extent with what I had been told, that it had been in a driving condition 35 years prior. As things have developed I now realize that was not the case. Everything about the car I have found indicated to me that the last effort made ca. 1984 was half cocked at best, I don't believe it has run let alone moved under its own power since being barned ~70 years ago. It isn't being run any more until properly serviced as you have said. No argument against the logic there.
