Note:
The correct oil level is only shown after switching off the engine for approx. >10 minutes.
An old gas station trick was for the attendant to put his finger between the dip stick and the engine so it would read a quart low, then he would show it to the customer and tell them they were quart low and sell them a quart of oil.

Well, when I was working at full-service stations during high school (in the '60's) we would always start the gas pumping, wash all the windows, and then do the underhood checks - to give the engine a bit of time to cool down and the oil level to settle.And this brings up a question I've always had.....how did the old Full Service stations ever get an accurate reading of the oil during a gas fill up? I was always told by my dad to wait 10-15 minutes.
