oiling system after shutdown question
 

so this came up in a discussion i had. i was talking about getting my turbo timer installed and i was told that my car should run the oiling system still after shutdown. i know some cars stil run coolant around after uve pulled the key, but idk about mine. it makes sounds like its still running something around for like 5 seconds after shutdown. it might be things just winding down cuz of enertia, but i dont know. can somebody shed some light on this?
