Q: Are Harley oil filters all the same?
A: No, Harley oil filters are not all the same. While they may share certain standard features, there are differences among various oil filters made by different manufacturers.

It's essential to choose an oil filter that matches your bike's requirements and meets the necessary quality standards.

Regular oil and filter changes help maintain engine performance, reduce wear, and prolong the life of your Harley motorcycle.

Q: Do you have to change the motorcycle oil filter every time?

The oil filter plays a crucial role in removing contaminants and debris from the engine oil, preventing them from circulating in the engine and causing potential damage. Replacing the oil filter ensures that your motorcycle's engine continues to receive clean oil and operates smoothly. Reusing a used oil filter, even after cleaning, may compromise its filtration efficiency and could lead to engine issues. To ensure optimal engine health and performance, it's best to use a new oil filter with every oil change.
