Alkylated naphthalene blendstock and processes for making the alkylated naphthalene blendstock are provided. The present processes comprise mixing an acid-form MWW-type catalyst, naphthalene, and a solvent to provide a reaction mixture and adding linear alpha olefins to the reaction mixture after heating. The resulting AN blendstock has an isomer ratio of less than 45 wt % mono alkylated naphthalene and greater than 55 wt % multi-alkylated naphthalene and can be combined with polyalphaolefin base stock to provide a synthetic lubricant formulation produced without triflic catalyst and with less process steps.

The disclosed technology relates to compositions suitable for use as lubricants and lubricant additive compositions which comprise a 1,4-benzoxazine-derived antioxidant, wherein the antioxidant itself may also be described as a 1,4-benzoxazine compound, and optionally comprising other additives suitable for lubricants, such as an anti-wear agent, a detergent, or a dispersant.

Lubricant compositions comprising an improved ashless organic friction modifier additive, capable of reducing both friction and wear, is provided. It has been found that mixtures of fatty-alkanolamides containing secondary hydroxyls on the amino alkyl substituent, such as amide mixtures prepared from bis(2-hydroxyporopyl)amine and mixtures of at least two different C.sub.8-24 fatty acids, provide better oil solubility and friction reduction than alkanolamides with primary hydroxyl functionality, such as amide mixtures prepared from di-ethanol)amine.

A multiphase composite lubricant for a railway lubricant stick that can be used in both low and high temperature applications. The composition of the multiphase composite lubricant includes an amount of a lubricant, an amount of a thermoplastic lattice components that forms a lattice structure, and a polymer extender.

The disclosed technology relates to a lubricating composition comprising an oil of lubricating viscosity and an ashless basic amine additive selected from a secondary amine containing -carbon aromatic substitution. The basic secondary amine additives used in the lubricating oils of the disclosed technology impart basicity measured as total base number (TBN) without adding sulfated ash. Lubricating oils containing the basic secondary amine additives of the disclosed technology simultaneously achieve seals compatibility, deposit, and corrosion control.

Fluids containing polyalpha-olefins (PAOs) may afford a number of benefits and be multi-functional in nature. Methods for using such multi-functional fluids may comprise: providing a multi-functional fluid comprising about 3 wt % to about 99 wt % of a polyalpha-olefin (PAO), based on a total weight of the multi-functional fluid; and contacting the multi-functional fluid with at least a portion of an electric drive unit. The PAO comprises about 10 mol % or less olefinic bonds and has a kinematic viscosity at 100 C. (KV100), determined pursuant to ASTM D445, of about 3.0 to about 4.5 cSt, and a Noack volatility (NV), determined pursuant to ASTM D5800, of about 15% or less.
