Can Semi-Synthetic Engine Oil Be Used for One Year?

[StKendra]

Semi-synthetic engine oil is not recommended for use over one year. Generally, mineral oil should be replaced every 3 months or 5,000 kilometers, semi-synthetic oil every 6 months or 7,500 kilometers, and full-synthetic oil every 12 months or 10,000 kilometers. Below are specific methods for selecting engine oil for your car: 1. Performance selection: If you prioritize the longevity of the oil, you can choose Mobil oil; if you focus on the oil's cleaning ability for the engine, Shell lubricants can be used; if you need lubricants with strong oil film toughness, Castrol is recommended. 2. Driving conditions: For frequent driving in congested areas, older vehicles, or long-distance heavy-load transportation, the viscosity of the lubricant can be appropriately increased. 3. Engine type: For naturally aspirated engines, mineral oil and semi-synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and operate under harsher conditions, requiring higher-grade lubricants with better fluidity, preferably full-synthetic oil.
