Abstract:
1. A super tractor oil universal lubricating composition comprising: a) an oil of lubricating viscosity having a viscosity index of at least about 95, formulated with additive components comprising: b) characterized in that a ratio between a content (ppm) of metal based on the total weight of the lubricating composition and a total base number of the lubricating composition (mg KOH/g) ranges from about 210 to about 450 (ppm/mg KOH/g); c) a ratio between the content (ppm) of the metal based on the total weight of the lubricating composition and a content (ppm) of phosphorus based on the total weight of the lubricating composition ranges from about 5.0 to about 20.0 (ppm/ppm); and d) a ratio between the content (ppm) of phosphorus based on the total weight of the lubricating composition and a content (ppm) of molybdenum based on the total weight of the lubricating composition ranges from about 0.5 to about 80.0 (ppm/ppm), wherein the lubricating composition is further characterized as having no water separation and no precipitate in a water tolerance test wherein the water separation and precipitate are measured by mixing 199.2 mL of the lubricating composition with 0.8 mL water in a blender, storing 100 mL of the resulting sample in a centrifuge tube for seven days, and centrifuging the sample to determine separation in the oil.
