Drystarting an engine

Dry Starting an engine refers to starting the engine without any lubrication.  Dry starting can cause damage to an automobile engine such as scoring on the pistons, the bearings, etc.  To prevent dry starting, large engines are provided with safety interlocks such that they cannot be started unless the lubrication oil pressure is above a certain level. 

Oils for automobile engines, today, have special properties such that the oil clings to the surface of the automotive parts.
