How Many Kilometers Should Mineral Engine Oil Be Changed?
2 Answers
Mineral oil needs to be changed every 5,000 kilometers. Generally, conventional oil requires replacement every 5,000 km, semi-synthetic oil every 7,500 km, and full synthetic oil every 10,000 km. Oil changes are not solely due to consumption; deterioration caused by time and environmental factors also necessitates replacement. The environmental factors here include both external conditions and the operating environment of the oil. More details are as follows: 1. Mineral engine oil is suitable for vehicle models with relatively low emission requirements, such as micro, compact, and economy cars priced around tens of thousands of yuan. 2. Since the engines of these vehicles are not very powerful, the perceived power loss due to oil performance degradation is minimal. Naturally, the impact on driving experience is also slight, often unnoticeable. Therefore, mineral oil can be chosen for these types of vehicles to achieve the most economical usage.
Mineral engine oil is generally recommended to be changed every 5,000 to 8,000 kilometers, but the specific interval should refer to the vehicle manufacturer's manual. Through my own research, frequent stop-and-go city driving causes oil to get dirty faster, so it's better to shorten the change interval. Over time, used oil loses its lubricating and cleaning properties, leading to engine wear or increased carbon deposits. Additionally, driving in dusty or high-temperature areas accelerates oil degradation, so changing around every 5,000 kilometers is advisable. Regular oil dipstick level checks are essential - I often remind my family to develop this habit. Never neglect this issue, otherwise engine repair costs could be very high.
