How to Determine Engine Oil Emulsification Issues?
1 Answers
Methods to determine engine oil emulsification issues: Open the engine oil cap and observe the back and underside of the oil 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. At this point, the oil has lost its effectiveness, with all functions degraded, and should no longer be used. The phenomenon of emulsification at the oil filler port occurs because the area near the oil filler inevitably comes into contact with air. Water vapor in the air condenses on the oil filler cap due to temperature changes, leading to slight emulsification.
