It is generally recommended to change your motorcycle's oil based on both mileage and time intervals, whichever comes first. While the manufacturer's recommended number of kilometers (or miles) is a guideline, there are other factors to consider that may necessitate an oil change even if you haven't reached that mileage yet. These factors include:
Time Interval: Oil can deteriorate over time, even if the motorcycle hasn't been ridden extensively. Exposure to heat, humidity, and contaminants can affect the oil's performance and lubricating properties. Therefore, it is recommended to change the oil at least once a year, even if you haven't reached the recommended mileage.
Riding Conditions: If you ride in severe or demanding conditions, such as extreme temperatures, dusty environments, or stop-and-go traffic, your motorcycle's oil may degrade more quickly. In such cases, it is advisable to change the oil more frequently, regardless of the mileage.
Storage: If your motorcycle has been stored for an extended period, the oil may degrade due to inactivity. Moisture accumulation and contaminants can affect the oil's quality. Therefore, it is recommended to change the oil before returning the motorcycle to regular use, regardless of the mileage.
Type of Oil: If you use synthetic oil, it typically has a longer service life compared to conventional oils. Synthetic oils often provide better lubrication and can withstand higher temperatures. However, it is still important to follow the manufacturer's recommendations for oil change intervals based on time and mileage.
To ensure optimal performance and protect your motorcycle's engine, it's best to consult the owner's manual for the specific recommendations from the manufacturer. Additionally, if you notice any signs of oil degradation, such as a change in color, viscosity, or a burnt smell, it is advisable to have the oil changed promptly, even if you haven't reached the recommended mileage interval. Regular oil changes are essential for maintaining the longevity and reliability of your motorcycle's engine.
