How Often Should Oil Be Changed in a Van?
1 Answers
Oil should be changed when it reaches its service cycle or when the mileage reaches 5,000 kilometers. Generally, the service cycle for mineral oil is six months, for semi-synthetic oil it is nine months, and for full synthetic oil it is one year. The following is an introduction to engine oil: 1. Function of engine oil: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. 2. Composition of engine oil: Known as the 'blood' of a car, engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, giving it new properties, making them an important part of the lubricating oil.
