while i think bob means well, spark analysis cannot give /any/
information on the organic content of oils, only the metallic. hence,
there's no real info on base stock, viscosity modifiers, seal
conditioners, detergents, antioxidants, etc.

i really have a problem by this spark analysis based endorsement of
motorcraft. so what if the metallics are present in the same quantities
as other oils? my hands-on real life experience is that motorcraft is
utter garbage. it makes honda oil seals leak like sieves and the engine
clatter like a bag of loose gonads. reverting to castrol gtx cured my
oil leaks and quietened the engine down completely.
