  • Publication number: 20040121918
    Abstract: The lubricating compositions of the present invention are designed for use in a four stroke outboard marine engine and contain an oil of lubricating viscosity, an ashless dispersant, a metal detergent, a rust inhibitor system comprising a combination of certain rust inhibitors with an ethoxylated alkyl phenol, a relatively high amount of ZDDP, and an amount of a molybdenum compound sufficient to provide the composition with 15-1,000 ppm by mass of molybdenum. An amount of about 15 ppm to 1,000 ppm by mass of molybdenum from a molybdenum compound has been found to be effective as an antiwear agent in combination with the high levels of ZDDP.

  • Publication number: 20030220207
    Abstract: According to the invention, a self contained vibration resistant bearing is provided. The bearing is coated with a film formed from a rust preventive oil having an extreme-pressure additive content of 0.5 to 10% by weight. Desirably the extreme-pressure additive is an organometallic compound, an organofatty acid compound, organofatty acid derivative, an organophosphoric acid compound or a combination of two(2) or more of such compounds. When a rust preventive film that contains an extreme-pressure additive is formed all over bearing components during the assembling process, the bearing components are fully protected even from sudden vibrations from transportation.
