The present invention relates to lubricating compositions and particularly gear oil compositions that include a specific class of substituted triazoles, where the substituted triazole includes at least one hydrocarbyl group linked to one of the nitrogen atoms in the triazole ring. Such compositions provide surprisingly good seal compatibility compared to compositions with other triazoles and/or alternative additives.

A method for producing a deposit resistant fluid includes combining a base stock and one or more additives to form a blended fluid configured to maintain fluidity in a low temperature environment and to resist forming deposits in an oxidizing environment. The base stock has a viscosity index of at least 80, and either a kinematic viscosity at 40° C. of at least 320 cSt or a kinematic viscosity at 100° C. of at least 14 cSt. The base stock includes greater than or equal to about 90 wt % saturates, less than or equal to about 10 wt % aromatics, and a sum of terminal/pendant propyl groups and terminal/pendant ethyl groups of at least 1.7 per 100 carbon atoms.

The present invention addresses a problem of providing a grease composition that uses hydrophilic nanofibers but still has excellent water resistance and does not readily experience oil separation. The grease composition contains a base oil, hydrophilic nanofibers having a thickness (d) of 1 to 500 nm, and an organic bentonite.

The present invention relates to a lubricant containing molybdenum sulfide particles, and the molybdenum sulfide particles contain molybdenum disulfide having a 3R crystal structure. The present invention relates to a lubricating composition containing molybdenum sulfide particles, which are the lubricant, and a base oil which is a mineral oil, a synthetic oil, or a partially synthetic oil.

The present invention provides a lubricant composition comprising: (i) a base oil (ii) an organophilic clay-based thickener; and (iii) a solid lubricant, wherein said solid lubricant does not comprise any heavy metals. The present invention also provides the use of a lubricant composition comprising: a base oil; an organophilic clay-based thickener; and a solid lubricant, wherein said solid lubricant does not comprise any heavy metals, as a pipe dope.
