This invention relates to a lubricating composition comprising a blend of a major amount of an oil of lubricating viscosity, gear or transmission oil package and a top treatment which comprises at least one saturated fatty phosphate ester or salt, wherein the lubricating composition is free of saturated fatty phosphites. Tin another embodiment, the invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, at least one saturated fatty phosphate ester or salt, at least one polysulfide and at least one phosphorus antiwear or extreme pressure agent, wherein the lubricating composition is free of saturated fatty phosphites. The invention relates to additive combinations which when added to a lubricant can provide and improve frictional and, optionally, thermal stability properties. The additives include a phosphate ester or salt wherein the hydrocarbyl group of the phosphate is a fatty-saturated group. The top treatment may also include a substituted fatty imidazoline or reaction product of a fatty carboxylic acid and polyalkylene polyamine and/or a borated dispersant.

This invention relates to mineral oil based gear oils and transmission fluids which comprise a major amount of a mineral oil having an iodine number of less than 9 and where at least 55% of the saturates are aliphatic, and gear oil or transmission fluid additives. In one embodiment, the invention relates to a gear oil or transmission fluid composition comprising a major amount of lubricant basestock and at least one functional additive wherein a major amount of the lubricant basestock comprises a mineral oil having an iodine number of less than 9 and comprising at least 45% by weight of aliphatic saturates. These gear oils and transmission fluids have good viscosity and oxidation properties.
