The specific replacement interval depends on the driving environment, especially for city driving where the vehicle often idles; in such cases, the replacement interval should be shortened. Types of Engine Oil: Generally, engine oil is categorized into 3 types: fully synthetic, semi-synthetic, and mineral oil. Replacement Intervals for Different Types of Engine Oil: Fully synthetic oil is typically changed every 10,000 kilometers or once a year. Semi-synthetic oil is usually changed every 7,500 kilometers or every 7 to 8 months. Mineral oil is generally changed every 5,000 kilometers or every 6 months.
