What happens if I accidentally put coolant in my oil?

No. Coolant in the oil will cause internal engine parts to be improperly lubricated and will cause premature failure. The oil should be changed before operating the engine.

What causes coolant and oil mix?

A blown head gasket is a common cause of oil mixing with coolant. This thin sheet of metal sits between the engine block and cylinder head to create an air-tight and liquid-tight seal. If it fails, oil and coolant may mix together. In some cases, coolant will enter the oil.
