Tested by Honda Research and Development and certified for use in all Honda marine engines, complying with all of Honda’s service and warranty requirements.
Honda FC-W 10W-30 Marine engine oil’s advantages over automotive oils include:
• Increased rust and oxidation inhibitors to fight corrosion in the marine environment
• Shear stable polymers to resist viscosity breakdown under high rpm and high load conditions
• Better anti-foaming characteristics to better protect the engine at high rpm
• Excellent performance in High Temperature High Shear Viscosity test to ensure viscosity retention despite the fuel dilution associated with marine engines
• Additional anti-wear additives for better bearing protection
