How to Deal with Water in Engine Oil?

[NadiaFitz]

The method to deal with water in engine oil is: do not start the engine, then check the cause of water leakage. After solving the problem, completely drain the original oil and replace it with new oil. Most of the additives in engine oil are surfactants, which are emulsifiers in a sense. When mixed with water and circulated by the pump or stirred, it is easy to emulsify into a brownish-yellow emulsion. If there is a large amount of water, it may even emulsify into a milky-white emulsion. Therefore, if the used oil appears milky white, it may be due to radiator leakage or external water mixing into the lubrication system. In this case, the oil should be drained and the vehicle should be inspected. Continuing to use such oil will not only reduce the strength of the oil film but also cause foaming or emulsification and deterioration of the oil. In mild cases, it may cause rusting of mechanical parts, and in severe cases, it may lead to serious mechanical accidents such as cylinder scoring or bearing seizure.
