What if I overfill my oil by half a quart?

An extra half a quart of oil in your crankcase is not going to do any harm to the engine. If the crankcase were seriously overfilled — say, more than a quart — then the spinning crankshaft could come into contact with the liquid oil, and churn it up. The oil pump can’t pump foam, so you could cook an engine that way.

What happens if you add an extra quart of oil to your car?

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.

What if the oil level is too high?

With too much oil in your engine, its fluid level in the oil pan will be so high that it can be splashed by some of the moving parts in the engine block, specifically the crankshaft lobes and connecting rod “big ends.” That, in turn, can whip the oil into a frothy consistency, like a well-emulsified salad dressing.
