How often should Mobil 1 5W-30 be changed?

[Juniper]

Synthetic oil should be changed every 8,000-10,000 kilometers or 10-12 months. Here are some details about synthetic oil: 1. Advantages of synthetic oil: Synthetic oil uses higher-grade base oil compared to semi-synthetic oil. The replacement intervals differ—semi-synthetic oil should be changed every six months or 7,500 kilometers, while synthetic oil should be changed annually or every 10,000 kilometers. Synthetic oil also has a wider operating temperature range. In the same working conditions, synthetic oil can protect the engine with lower viscosity, whereas semi-synthetic oil has relatively higher requirements. 2. Replacement interval: SL-grade synthetic oil should be changed annually or every 10,000 kilometers.
