What happens if you overfill your oil?

What does bubbles in my oil mean?
Frothy Oil If your oil is bubbly or foamy but not discoloured then you may have overfilled the sump. The oil is essentially being churned and aerated by the crank and can cause a lot of damage very quickly. If the foam is lighter in colour this could be down to water or coolant contamination.
