Your oil in your car is milky colored?

Milky oil in a car is a serious problem, indicating the presence of water in the engine oil. This is never normal and requires immediate attention. Possible causes include a blown head gasket, a cracked engine block, or a failing coolant system. Driving with milky oil can cause serious engine damage, leading to costly repairs or even a complete engine failure. The car should not be driven until the cause is diagnosed and repaired by a qualified mechanic.
