How often should I clean this filter?

That depends on your driving conditions. aFe recommends inspecting the filter regularly and cleaning it when you notice a buildup of dirt and debris. Clean it more often if you drive in dusty conditions.

What is the best way to clean this filter?

aFe recommends using their filter cleaning solution and a soft brush. Apply the cleaning solution, let it soak, then rinse the filter with water from the inside out. Allow the filter to air dry completely before reinstalling.

Does this filter require oiling?

No, this is a Pro DRY S filter, which uses a three-layer synthetic media that does not require oiling. This makes cleaning and maintenance much easier, as you don't have to worry about properly oiling the filter after each cleaning.
