Volkswagen Jetta recommends using semi-synthetic engine oil with the specification of 5w40 (4L), and the replacement cycle is 10,000 kilometers. For oil brands, you can choose international brands such as Mobil, Shell, Castrol, and Total, or domestic brands such as Great Wall, Kunlun, Tongyi, and Longpan. The following is an introduction to engine oil: 1. Engine oil is the lubricant used by the engine, composed of base oil and additives. 2. The density of engine oil is about 0.91×10³ (kg/m³). It can lubricate and reduce wear, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and absorb shock for the engine. It is known as the "blood" of the car.
