ISX, Oil check procedure?

[Waterloo]

I tell the oil changer to put 42 quarts in and then I add my gallon of Sta-Lube... Check cold in the morning and when fueling... I leave the hood up, go pay, come back and check oil. That should be plenty of time to let the oil drain down into the pan. It normally hovers around the full mark, still nice and clear too... ;-)
