...Which begs the question:
How long will this engine sit before it is started?  Know what engine plants use?  A very light oil, especially on cylinder walls.  It would remind you of WD-40.  They "cold test" the engine first (which gets all the parts going under normal oil pump pressure, but no spark).  If all the test results are "go", the engine goes to "hot test" where it gets a good run for ten minutes under its own power.  Good engines go right to the rack, and off to the assembly plant.  "Bad" engines get torn down.  They use regular multi-grade oil with dye in it.  If there is a leak, a black light makes the dye jump right out as a white color.

For many years I have mixed regular 10W-30 with STP.  STP alone is way too thick, but it does a good job of sticking to everything.  I like it to stick, but I also like it to flow (especially when running-engine oil mixes with it).  I coat everything with it except cylinder walls.  For cylinder walls... you guessed it, WD-40.  It is the best for new rings on new cross-hatch.
