Proper Suzuki Engine Maintenance

Routine oil service is essential for keeping your Suzuki outboard reliable with a long lasting life. Here's what you need to know to keep your engine at peak performance.

Suzuki 2 Stroke Outboards

2 stroke models don't require a traditional oil change but instead blends oil during the process. It is important to check and refill the oil reservoir, if oil injected, regularly. We recommend using a high-quality TC-W3 certified marine oil.

Suzuki 4 Stroke Outboards

4 stroke models have separate oil and fuel, meaning you will have to perform regular oil changes to keep it running smoothly. Suzuki recommends changing the oil and filter every 100 hours or at least once a season, whichever comes first.

Grade Oil Type Highlights
Good Mineral/Conventional Cheapest option, breaks down faster requiring more frequent oil changes
Better Semi-Synthetic Better cold-start protection, resists breakdown, balances cost and performance
Best Full Synthetic Maximum protection, higher upfront cost but longer lasting

Proper Suzuki Engine Oil Maintenance Schedule

Initial Break In Service 

For new engines it is recommended to change the oil and filter after the first ~20 hours of run time. This removes any contaminants or metal particles from the break in process.

Every 100 Hours of Annually

Perform an oil and filter change every 100 hours of operation or once a year, whichever comes first. This interval helps maintain lubrication quality and engine efficiency.
