It is generally recommended to change the oil in a motorcycle before storing it for the winter. Here's why:
Fresh oil: Changing the oil before winter ensures that your motorcycle's engine is filled with fresh oil that has the appropriate viscosity and additives. Fresh oil helps to protect the engine during the storage period, preventing contaminants and moisture from causing damage.
Contaminant buildup: If you leave old oil in the engine over the winter, it can lead to the accumulation of contaminants, such as dirt, metal particles, and combustion byproducts. These contaminants can settle and potentially cause harm to engine components when the motorcycle is not in use for an extended period.
Moisture prevention: During winter storage, moisture can condense inside the engine due to temperature fluctuations. Moisture can lead to corrosion and damage internal engine parts. By changing the oil before winter, you reduce the amount of moisture present in the engine, minimizing the risk of corrosion.
It's important to follow the manufacturer's recommendations regarding oil change intervals and consult your motorcycle's owner's manual for specific guidance on winter storage and maintenance. Additionally, if you plan to ride your motorcycle during winter or in colder climates, it's crucial to use oil that is suitable for lower temperatures to ensure proper lubrication and protection.
