The invention relates to lubricants which contain a phosphorus to nitrogen ratio of &#x2267;1.0 and a sulfur content of &#x3e;1.4 wt. %. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or 'green gears', during the break-in phase.

Fluids for enhanced gear protection

The invention relates to compositions suitable as additive packages for lubricants and other functional fluids, the composition comprising sulfur-containing extreme pressure components, phosphorus-containing anti-wear additives, a triazole-containing species. A preferred use is in industrial gear oils. In embodiments, enhance protection in the areas of bearing wear and micropitting are obtained.

Additive system for lubricants

The invention relates to lubricating fluids and oil formulations which provide exceptionally low traction, a method of lowering traction coefficients in lubricating compositions, and to uses of such compositions.

Lubricating fluids with low traction characteristics

The invention relates to additive systems which contain a phosphorus to nitrogen ratio of &#x2267;1.0. The phosphorus contribution is primarily from an acid phosphate species and the sulfur content is primarily from an antiwear agent. This lubricant composition has been found to provide exceptional protection to new gears or 'green gears', during the break-in phase.
