Note:Regularly monitoring the oil level in your motorcycle is essential for maintaining optimal engine performance and longevity. While the engine oil typically has a lifespan of 5 to 8 years when stored properly in an unopened bottle, once opened, its effectiveness diminishes within 6 months. Therefore, it's advisable to change the oil every 6 months or based on the mileage recommendations provided in your owner's manual. Following these guidelines ensures that your engine remains well-lubricated and protected against wear and tear.
