What kind of engine oil is best for Toyota Yaris?

[MacKylie]

Toyota Yaris is most suitable for using 5W-30 semi-synthetic engine oil, which has the advantage of good lubrication effect and can effectively protect the engine. In the 5W-30 model engine oil, each symbol represents a different meaning. W, which stands for winter. The number before W is 5, the smaller the number, the better the fluidity of the engine oil at low temperatures, and the lower the applicable minimum temperature. 5W means it can be used at temperatures above -30 degrees Celsius. The number 30 after W refers to the viscosity of the engine oil at 100 degrees Celsius. The larger the number, the higher the viscosity of the engine oil, the stronger the ability to withstand high temperatures, and the better the high-temperature protection performance. Engine oil is divided into full synthetic oil, semi-synthetic oil, and mineral oil. Full synthetic oil should be replaced every 10,000 kilometers or 1 year; semi-synthetic oil should be replaced every 7,500 kilometers or 7-8 months; mineral oil should be replaced every 5,000 kilometers or 6 months.
