Local aircraft engine overhauler uses a mix of stp, lubriplate, and non 
detergent oil as an assembly lube.  The problem with using just straight 
oil (he feels anyways) is that if the engine sets for any length of time 
after assembly with straight oil that it tends to leak out of the 
bearings leaving a dry bearing for the first start. 

  I've always used a film of moly grease and maybe a little oil on most 
everything, including piston skirts.  Oil only, maybe on cylinder walls 
but I keep the rings dry (rather than soaked in oil) since my dealings 
with Total Seal.  Seems to work.  
  Had a head I'd assembled, get put on a block with OBEN down 
(head gasket) and they drove it at least 100 miles with no oil to the 
head.  When I inspected it all looked fine.  So fine I pondered for a 
second or two the possibilities of running without oil to the head!  ;-)
