Suzuki uses a handful of oil filter part numbers across the DF lineup, and the number depends on the engine family, not the horsepower alone. The chart below is taken from Suzuki's 2025 maintenance manual; match your model and year before ordering.
Suzuki's schedule: replace the oil filter at the initial 20 hours or 1 month, then every 200 hours or 12 months (engine oil itself every 100 hours). Genuine Suzuki filters are built to the bypass pressure and filtration Suzuki specifies; a look-alike aftermarket filter is not.
