What type of engine oil is suitable for Vios?

[OOmar]

Vios can use engine oil with a viscosity of 5W-30. Mainstream engine oil brands include: Mobil, Castrol, Shell, and Dusso Lubricants. Engine oil plays multiple roles such as lubrication and wear reduction, auxiliary cooling, sealing and leakage prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the "blood" of a car. Below are some related details: 1. Engine oil consists of base oil and additives. Base oil is the main component of lubricants, determining their fundamental properties, while additives compensate for and improve any shortcomings in the base oil's performance, providing certain new characteristics. Additives are an essential part of lubricants. 2. The SAE viscosity classification for winter oils includes grades: 0W, 5W, 10W, 15W, 20W, 25W. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. 3. The SAE viscosity classification for summer oils includes grades: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. 4. The SAE viscosity classification for all-season oils includes grades: 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W-30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, 20W-50. The smaller the number representing the winter part (indicating a lower applicable minimum temperature), and the larger the number representing the summer part (indicating a higher applicable maximum temperature), the wider the applicable temperature range.
