[Ellen]

Dewei D30 uses 5W30 engine oil. Engine oil, also known as engine lubricant (English name: Engine-oil), serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the 'blood' of a car. Below are some relevant introductions about engine oil: 1. Functions of engine oil: Engine oil lubricates and reduces wear, aids in cooling, seals and prevents leaks, protects against rust and corrosion, and absorbs shocks. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its lifespan. 2. Choosing engine oil: The selection of engine oil should not be based on price alone but should consider the characteristics of the car's engine and driving habits. It is most appropriate to choose the right engine oil accordingly. Engine oil can also be categorized based on winter and summer use. For winter, the primary consideration is the low-temperature viscosity grade. In summer, due to higher temperatures, there is no need to select engine oil with a superior low-temperature viscosity grade.
