The differences between 10w40 and 5w30: 1. Different freezing point temperatures: The freezing point temperature of 10w40 is minus 25 degrees; the freezing point temperature of 5w30 is minus 30 degrees. 2. Different viscosities: The viscosity of 10w40 is 40; the viscosity of 5w30 is 30. Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion prevention, and shock absorption, and is hailed as the lifeblood of a car. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties; the additives can compensate for and improve the shortcomings of the base oil's performance, imparting certain new properties, making them an important part of the lubricant.
