What kind of engine oil is suitable for Vios?
2 Answers
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 roles such as lubricating and reducing wear, assisting in cooling, sealing to prevent leaks, preventing rust and corrosion, and damping vibrations, and is known as the "blood" of a car. Below is relevant information: 1. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil, imparting certain new properties, making them an important part of lubricating oil. 2. The winter oil grades in the SAE lubricating oil viscosity classification are: 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 summer oil grades in the SAE lubricating oil viscosity classification are: 20, 30, 40, 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. 4. The all-season oil grades in the SAE lubricating oil viscosity classification are: 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 (the lower the applicable minimum temperature), and the larger the number representing the summer part (the higher the applicable maximum temperature), the wider the applicable temperature range.
When it comes to the Vios compact car, I must emphasize the importance of oil selection. The manufacturer generally recommends 5W-30 synthetic or semi-synthetic oil, as clearly stated in the manual, which suits most driving conditions. Lower viscosity offers multiple benefits – quicker cold starts in winter and more stable protection in summer. Avoid using thicker oils like 10W-40, as they may cause a significant increase in fuel consumption. Driving habits also matter: frequent highway driving or urban traffic congestion puts greater pressure on the oil, so API SN grade is advisable. DIY oil changes are straightforward and cost-effective – a 4-liter bottle suffices, requiring just a wrench and drain pan. Regular oil changes are essential: every six months or 5,000 km to prevent carbon buildup and extend engine life. For guaranteed reliability, prioritize 4S dealerships or reputable service centers for inspections – never compromise safety to save money.
