How to Determine Oil Emulsification?
1 Answers
Methods to determine oil emulsification: Open the engine hood and observe the area behind and below the oil filler cap. If there is a thick layer of sticky liquid resembling chocolate milk or the oil appears milky white or creamy yellow, looking like a batter mixed with water and containing bubbles, it indicates that the engine oil has emulsified and deteriorated. Emulsified oil has lost its effectiveness, with all its functions diminished, and should no longer be used. The presence of emulsification near the oil filler port is due to the contact with air, where water vapor in the air condenses on the oil filler cap with temperature changes, leading to slight emulsification.
