What causes the increase and emulsification of engine oil in the Lexus NX?
2 Answers
The reasons for the increase and emulsification of engine oil in the Lexus NX are: 1. A large amount of gasoline is injected during engine startup, and cold starts and cold seasons cause the oil temperature not to rise, making it difficult for gasoline to evaporate, resulting in an increase in oil volume; 2. Emulsification caused by water mixing into the engine oil. The Lexus NX is a mid-size car with body dimensions of: length 4640mm, width 1845mm, height 1645mm, wheelbase 2660mm, and a body structure of a 5-door, 5-seat SUV. The Lexus NX is equipped with a 2.0L naturally aspirated engine and a 2.5L naturally aspirated engine, paired with a continuously variable transmission (CVT) and an electronic continuously variable transmission (e-CVT).
When I encountered the issue of oil dilution and emulsification in my Lexus NX, I did some research and found that it might be caused by the design of the direct-injection engine. During short-distance driving, incomplete combustion of gasoline can seep into the engine oil, or coolant leakage can mix with the oil, causing it to thin and foam. Some Lexus models are prone to this common issue, and it needs to be addressed promptly to avoid engine damage. I often remind car owners to pay attention to dashboard warning lights and regularly check the oil dipstick and coolant levels. If you notice a sweet smell or white foam, take the car to a shop immediately for a diagnostic scan to avoid major repairs. Safety first—don’t delay. Replacing the oil and conducting system tests can extend the car’s lifespan.
