Over time, oil can degrade and go bad even when sitting in a motorcycle engine. While the engine is not running, the oil can be subjected to various factors that contribute to its degradation. Some of these factors include:
Oxidation: Exposure to oxygen in the air can lead to the oxidation of oil, causing it to break down and lose its lubricating properties.
Contaminant Accumulation: Particles, moisture, and other contaminants can find their way into the oil while the motorcycle is inactive. These contaminants can alter the oil's composition and reduce its effectiveness.
Temperature Fluctuations: Extreme temperature changes can cause the oil to expand and contract, leading to changes in viscosity and overall oil quality.
Additive Separation: Over time, certain additives in the oil may separate or settle, reducing their effectiveness.
It's important to note that the rate at which oil deteriorates can vary based on factors such as the type of oil, storage conditions, and the length of time the motorcycle remains inactive. As a general guideline, it is recommended to change the oil in your motorcycle engine at regular intervals, even if the motorcycle is not being used frequently.
Consult your motorcycle's owner manual or follow the manufacturer's recommendations for oil change intervals to ensure optimal engine performance and longevity. Additionally, if you plan to store your motorcycle for an extended period, it's advisable to perform an oil change before storage to help protect the engine during the inactive period.
