Suzuki oil filters – the right filter for your engine model
In the Suzuki oil filters product group you will find original Suzuki oil filters for outboard engine oil changes. The selection includes filters for, among others, the DF4/5/6 series (model years 2002–2013), the newer DF4A/5A/6A series, and the DF9.9 and DF15 series (1996–2010) – the filter is always specific to the engine horsepower and model year, so check the model and year of manufacture of your engine before ordering, as a filter of the wrong size will not screw on properly and will not filter effectively.
It is a good idea to change the oil filter every time you change the oil, not just every other time – the filter collects metal particles and impurities, which in the old filter are partially recirculated with the new oil. Always use genuine Suzuki oil when changing the filter and lubricate the filter sealing ring with a thin layer of oil before installation so that it tightens evenly without the risk of leakage.
If you are unsure of the filter model for your engine, check the engine nameplate or owner's manual - Suzuki has used several filter versions within the same model series in different production years. Other Suzuki service accessories, such as fuel filters and switch panels, can be found in the Suzuki other spare parts product group .
The consequences of an incorrect or unreplaced oil filter often become apparent only after a longer period of time: a worn filter no longer effectively retains metal particles, which then circulate back into the engine's lubrication system and accelerate wear on bearings and cylinders. Suzuki recommends replacing the oil filter with every oil change, typically every 100 hours of operation or once a season - the exact interval can be found in the owner's manual for your particular engine model, as it can vary between model series.
It is recommended to use a filter wrench to remove and tighten the filter, as hand tightening often leaves the filter loose, and overtightening with a tool can damage the sealing ring. Tighten the filter to the manufacturer's torque specifications, or, if a torque wrench is not available, hand tighten and then tighten it about a third of a turn with a tool. After starting the engine, always check for oil leaks around the filter before you go out on the water - a small leak is much easier to spot and fix on the dock than at sea.
It is always a good idea to replace the O-ring on a Suzuki filter with a new one, even if the old seal still looks intact – the disposable seal is not designed to be reinstalled, and a used ring may leak even if it looks visually intact.
