Is car maintenance calculated by age or mileage?
2 Answers
Car maintenance intervals are determined by whichever comes first: mileage or age. Generally, engine oils are categorized into three types: full synthetic, semi-synthetic, and mineral oil. Below are the recommended replacement intervals for different types of engine oil: 1. Full synthetic oil typically requires replacement every 10,000 kilometers or once a year. 2. Semi-synthetic oil usually needs replacement every 7,500 kilometers or every 7-8 months. 3. Mineral oil generally requires replacement every 5,000 kilometers or every six months. Note: Prolonged failure to change the engine oil can lead to oil degradation, reducing its lubricating effectiveness. Without proper lubrication during engine operation, internal components may wear out, shortening the engine's lifespan.
From my perspective, car maintenance is typically based on the manufacturer's recommendations, considering whichever comes first between the age of the car and the mileage. Having driven several cars, I've noticed that the owner's manual for each brand provides detailed maintenance intervals, such as recommending an oil change every 5,000 kilometers or 6 months, whichever comes first. This is because parts naturally age or wear out from excessive use. If you only focus on mileage, over time, fluids can deteriorate and potentially corrode the engine. Conversely, a newer car driven extensively can increase mechanical stress. Therefore, developing a habit of recording the time and mileage of your last maintenance and acting on schedule can make your car more durable. Don't overlook small details like regular checks of air filters and tires, which can extend the vehicle's lifespan and enhance safe driving. Overall, following the manual is the most reliable approach—don't make assumptions on your own.
