If you are talking about a lube between the crank and seal lip, Mobil 1 or other high quality oil is fine -- providing you are going to start the engine up faily soon --within a week or so.
Engine builders will use a lube that is more of a grease such that it will remain on the crank and seal during prolonged storage and still provide good lube at initial startup. That way when the engine sits around for a few months before initial fire up the seal is lubricated with the grease until oil from the engine provides the lube. This type of lube is used throughout the engine (bearings, cams, lifters,sliding surfaces, etc) during engine assy as well -- to provide the lube during initial startup.
