It's not "high moly" except by accident.
Excerpts from the August 2006 edition of Honda Service News:
"The engine oil looks that way because of
molybdenum (that’s “moly” for short), a special
lubricant applied by the factory to critical engine
components during assembly.
"When the engine is test-run, that molybdenum
mixes with the engine oil, turning it a dark
metallic color often within the first 5 minutes of
running. And just how dark that engine oil turns
seems to vary between vehicle models, engine
types, and engine assembly plants.
"What’s really important to remember here is this:
Don’t change the factory-fill engine oil because it
looks dark; just make sure it’s at the right fluid
level. To ensure proper engine break-in, the
factory-fill engine oil needs to remain in the
engine until the first scheduled maintenance
interval."
