摘要： 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, 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.

摘要： The concentrates comprise specified proportions of diluent oil, an organic sulfur-containing antiwear and/or extreme pressure agent, an ashless dispersant, a dimethyl ester of an aliphatic phosphonic acid in which the aliphatic group has an average in the range of about 12 to about 24 carbon atoms, and a 3-hydrocarbyl-2,5-diketopyrrolidine in which the hydrocarbyl group is an alkyl or alkenyl group having an average in the range of about 12 to about 30 carbon atoms. By using weight ratios of diketopyrrolidine to the dimethyl phosphonate of at least 3:1, the concentrate remains homogeneous at temperatures at least as low as 12.degree. C. When utilized as a top treat in gear oils formulated with conventional GL-4 and GL-5 gear additive packages substantial improvements in limited slip axle performance can be realized.

摘要： An ashless or low-ash oleaginous liquid composition comprising a major amount of hydrogenated poly-.alpha.-olefin oligomer fluid having a viscosity in the range of about 2 to about 10 cSt at 100.degree.C., and minor amounts of at least the following: A) hydrogenated poly-.alpha.-olefin oligomer fluid having a viscosity in the range of about 40 to about 120 cSt at 100.degree.C.; and B) antiwear/extreme pressure agent selected from phosphorus-containing ashless dispersant, boron-containing ashless dispersant, and phosphorus- and boron-containing ashless dispersant. Compositions of this type can be formed having excellent high and low temperature viscosity characteristics and excellent shear stability. To this end, the preferred compositions are devoid or substantially devoid of conventional polymeric high molecular weight viscosity index improvers.
