Has the 2021 Toyota Hybrid Engine Oil Emulsification Issue Been Resolved?
1 Answers
Toyota hybrid engine oil emulsification issue has not been resolved yet. Hazards of engine oil emulsification: Oil and water are immiscible, but under certain temperatures and specific conditions, they can mix and cause emulsification. Emulsified oil appears white in color. Since engine oil lubricates engine components, its performance significantly deteriorates after emulsification, leading to severe engine wear and reduced engine lifespan. Therefore, engine oil emulsification is not a minor issue. Normal engine oil emulsification phenomenon: Sometimes, when the engine is turned off and cools down, air enters the valve chamber where the camshaft is located. The condensation of water vapor in the air can cause slight emulsification on the oil cap. The accumulation of emulsion on the oil filler cap is entirely different from the engine oil emulsification issue. This is a normal occurrence and does not fall under the category of engine oil emulsification problems.
