Note:Regularly monitoring the oil level in your motorcycle is crucial for its proper functioning. While engine oil typically maintains its quality for 5 to 8 years when stored in a sealed container, this duration decreases to just 6 months once the bottle is opened. Therefore, it's important to replace the oil every 6 months to ensure optimal performance and engine health. Alternatively, you can also change the oil based on the mileage specified in your motorcycle's manual for added convenience and reliability.
