What does it mean when gasoline appears milky white?

This phenomenon is called engine oil emulsification. The main cause of oil emulsification is that during engine operation, some gases enter the crankcase through cylinder gaps. These gases consist of water vapor, gasoline vapor, and combustion exhaust. Mild oil emulsification is not a serious issue and does not affect the normal operation of the engine. Here are detailed explanations about it: 1. Explanation one: The appearance of white emulsion on the gasoline cap may indicate that water has mixed into the engine oil, causing the oil's viscosity to fail. This prevents proper lubrication of all rotating parts that require it, leading to severe consequences. 2. Explanation two: Once white emulsion appears on the oil cap, it should be taken seriously. After analyzing the cause, promptly take the vehicle to a service center for appropriate maintenance or component replacement.
