How Often Should Engine Oil Be Changed in Car Maintenance?

[VanSteven]

Car maintenance and engine oil change intervals depend on the type of oil used in the vehicle. How often the oil should be changed is related to many factors, including the quality of the oil used, the driving environment in the region, the age of the vehicle model, and more. There is a wide variety of engine oils on the market, but the most reliable method to determine the oil change interval, grade, and quality is to follow the recommendations in the vehicle's owner's manual. The specific details are as follows: 1. Fully synthetic oil: Generally, fully synthetic oil should be changed every 10,000 kilometers or once a year. 2. Semi-synthetic oil: Generally, semi-synthetic oil should be changed every 7,500 kilometers or every 7-8 months. 3. Mineral oil: Generally, mineral oil should be changed every 5,000 kilometers or every 6 months.
