Most of you are too young to remember when service station attendants not only pumped your gas but checked your oil and cleaned your windshield as well. And they did every mechanical repair dealers did. There were so many you had your choice of mechanics, since like always there's good mechanics and bad mechanics. So oil was checked after letting the car sit for a minute or two or three.
