Engine using oil - problem ?

[2017EX_imp]

For my oil level checks, I use the start and idle 3 to 5 minutes from cold, then let it sit 3 to 4 minutes before checking the oil level, as outlined in the manual. I am guessing that the oil capacity spec. in the manual is for a completely empty engine and new oil filter. It seems that there is always a little oil that does not drain from the sump, and a little more trapped on the old filter, during an oil and filter change, which may or may not be part of the difference Memphismike mentioned.
