Semi-synthetic oil offers improved performance and protection, while fully synthetic oil provides the highest level of lubrication and engine protection.

5. Viscosity Ratings

Another important factor to consider when choosing outboard motor oil is its viscosity rating. Viscosity refers to the thickness or resistance to flow of the oil. The viscosity rating is denoted by numbers, such as 10W-30 or 20W-50. The first number represents the oil’s viscosity at low temperatures, while the second number represents its viscosity at high temperatures. It’s crucial to consult your motor’s manual to determine the recommended viscosity range for your specific engine.

6. OEM Recommendations

To ensure optimal performance and longevity of your outboard motor, it’s always best to follow the manufacturer’s recommendations. OEM (Original Equipment Manufacturer) recommendations for oil type and viscosity can be found in your motor’s manual. These recommendations are based on extensive testing and research conducted by the manufacturer to determine the best oil for their specific engines.

7. Environmental Considerations

When choosing outboard motor oil, it’s essential to consider the impact on the environment. Look for oils that meet or exceed environmental standards, such as TC-W3 certification for two-stroke oils and FC-W certification for four-stroke oils. These certifications ensure that the oil is designed to minimize pollution and meet stringent requirements for marine engines.

8. Storage and Shelf Life

Proper storage and handling of outboard motor oil are crucial to maintaining its effectiveness. It’s important to store oil in a cool and dry place, away from direct sunlight or extreme temperatures.
