Why would anyone want to check the oil? The engineer is doing exactly as directed. This is today, not our parents do-it-yourself generation.
Either the oil is staying at the proper level or it is not. Either way it is something for the dealer's service dept to check and deal with during regular service intervals. Oil is no longer an owner issue.
Old fashioned concern with unreliable owner-oriented service procedures went away a decade ago. Back when retaining the owner's "right to repair" was considered and then disgarded.
