What type of oil should I use in my Suzuki outboard?

We suggest that customers use genuine Suzuki 4 Cycle Engine Oil. We feel our oil is the best available on the market today. Our oils are formulated to provide superior lubrication and protection for internal engine parts in the harsh marine environment. Suzuki oil meets the National Marine Manufacturer Association (NMMA) Four Cycle Water Cooled (FC-W) standards. The actual oil recommendation is: SAE or NMMA FC-W 10W-40 (operating in temps from 14 degrees to over 100 degrees F) or 10W-30 (operating in temps from -4 degrees to 86 degrees F) API or NMMA FC-W Classification SE,SF,SG,SJ. For temps below -15 degrees F use SAE or NMMA FC-W 5W-30.
