While it is technically possible to change the oil in a motorcycle without changing the oil filter, it is generally recommended to replace the oil filter whenever you perform an oil change. Here's why:
Contaminant Removal: The oil filter is designed to remove contaminants, such as dirt, metal particles, and debris, from the oil as it circulates through the engine. Over time, the filter becomes saturated with these contaminants, reducing its effectiveness. By replacing the oil filter, you ensure that fresh, clean oil is being filtered properly, promoting better engine performance and longevity.
Oil Quality: Over time, oil breaks down and loses its lubricating properties. By changing the oil filter along with the oil, you ensure that the new oil is not immediately contaminated by the residual contaminants trapped in the old filter. Fresh oil combined with a new filter provides optimal lubrication and protection for your engine.
Warranty Requirements: In some cases, if your motorcycle is under warranty, the manufacturer may require you to change the oil filter during each oil change to maintain warranty coverage. Be sure to consult your motorcycle's owner's manual or contact the manufacturer to understand their specific recommendations and requirements.
While it may save you some money in the short term to skip changing the oil filter, it is generally considered good maintenance practice to replace both the oil and the filter simultaneously. It helps ensure optimal engine performance, prolongs the life of your motorcycle, and maintains warranty compliance if applicable.
