Yes, it is possible. Overfilling an engine with oil, is just as bad as not having enough oil. When an engine has been overfilled, the crankshaft will whip the oil causing caveatting. This causes air to be trapped in the oil. This trapped air causes a loss of lubrication and in some cases can cause serious engine damage. I am not talking about adding 1 pint too much and cannot tell you what too much is. It is different on different engines. Drain out any excess oil and fill it to the full mark and no more.

Why is smoke filling up a room diffusion?

Smoke filling up a room is an example of diffusion because the smoke particles move from an area of high concentration (where the smoke is generated) to an area of low concentration (the rest of the room) in order to reach equilibrium. This is due to the random motion of the smoke particles.
