Lubrication is lubrication...a little different stuff on assembly shouldn't hurt. Different stuff in the oil pan (i.e. synthetic) is a different story and can be a real problem. Assemblyt stuff all gets scraped off (by the rings) in no time anyway. I would be more worried about the rust you mentioned. Could have scored the cylinder walls a bit as it was scraped free by the rings. I would suggest driving it a bit more to see if things improve.
