What happens if the oil level is too high?
When too much oil is added, the level in the oil pan becomes too high. That allows a fast-moving lobed rod called the crankshaft to come into contact with the oil and essentially aerate it. The result is a foamy, frothy substance that cannot properly lubricate the engine.
Is it better to drain oil hot or cold?
Most oil experts say it’s better to drain the oil when it’s hot instead of when it’s cold, for several reasons: Oil viscosity is thinner when it’s hot, so it drains more quickly and completely out of the engine than when it’s cold.
