What type of engine oil is suitable for Toyota Yaris?

[DelKinsley]

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 engine oil model, each symbol represents a different meaning. W 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 fully synthetic engine oil, semi-synthetic engine oil, and mineral engine oil. Fully synthetic engine oil should be replaced every 10,000 kilometers or 1 year; semi-synthetic engine oil should be replaced every 7,500 kilometers or 7-8 months; mineral engine oil should be replaced every 5,000 kilometers or 6 months.
