When should you add engine oil? Don't overfill your engine!

Soooo many people think they have to add engine oil way before they actually should. The two marks are ADD and FULL. Don't add oil unless you can see the ADD line, everything above ADD is a-okay!
Overfilling your engine just wastes engine oil, and if you really really overfill it you can aerate your oil which can kill an engine. You have to add a lot more than the FULL mark to do that, but just saying.
So keep your oil above ADD and below FULL. That is the way to get it done!

To check oil and transmission on my box truck is it better on engine or off?
