What Causes Increased Engine Oil Level and Emulsification in the 2021 Toyota Models?
1 Answers
Reasons for increased engine oil level and emulsification: 1. Increased engine oil level: When the engine frequently operates under low-temperature and low-speed conditions, the oil temperature does not rise sufficiently. Water and gasoline mixed in the oil fail to evaporate, accumulating over time and causing the oil level to increase. 2. Engine oil emulsification: The essence of oil emulsification is the mixing of water and oil, resulting in a white emulsion. The causes of oil emulsification include the condensation of water vapor in the crankcase under low temperatures, which then permeates into the oil, and the tendency of ethanol gasoline to absorb moisture, introducing water from the air into the engine cylinders. When a vehicle operates for extended periods under low-temperature and low-speed conditions, the water cannot evaporate and remains trapped in the oil, leading to emulsification issues when mixed together.
