A method for improving friction and wear control, while maintaining or improving energy efficiency, in an engine or other mechanical component lubricated with a lubricating oil, by using as the lubricating oil a formulated oil. The formulated oil has a composition including at least one lubricating oil base stock. The at least one lubricating oil base stock includes one or more liquid crystals, wherein the one or more liquid crystals are represented by the formula:

A(R1).sub.n

wherein A is a mono-ring or a multi-ring aromatic group, R1 is the same or different and is a substituted or unsubstituted, hydrocarbon, alkoxy, or alkylthio group having from 2 to 24 carbon atoms, and n is a value from 1 to 12. The lubricating oil base stock has a kinematic viscosity of 2 cSt to 200 cSt at 40 C., as determined according to ASTM D445, and a kinematic viscosity of 1 cSt to 25 cSt at 100 C., as determined according to ASTM D445.

Provided is a lubricant base stock, a lubricating oil including the lubricant base stock and a method for improving viscosity temperature performance or viscosity index of an engine or other mechanical component lubricated with the lubricating oil. The lubricant base stock includes one or more liquid crystals represented by the formula:

R1-(A).sub.m-Y(B).sub.nR2

wherein R1 and R2 are the same or different and are a substituted or unsubstituted, alkyl or alkoxy group having from 0 to 24 carbon atoms; A and B are the same or different and are a cycloaliphatic group or aromatic group, provided at least one of A and B is an aromatic group; Y is a covalent bond, CH2-CH2-, CHCH, CC, OCOO, COO, CO, CSO, CSS, CS, O, S, SO, SO2-, CH2O, OCH2O, NO, ONO2, COOH, OH, or CN; and m and n are independently 0, 1, 2 or 3. The lubricant base stock has a kinematic viscosity of 2 cSt to 28 cSt at 40 C., and 1 cSt to 12 cSt at 100 C.

The invention to which this application relates is improvements to the provision of Molybdenum and/or Tungsten containing coatings of the type which can be used to improve certain characteristics of the surface of a substrate to which the coating is applied. In one embodiment the coating also includes Ti to provide the advantages of high adhesion, high humidity and wear resistance of the coating and TiB.sub.2 to promote the formation of a relatively uniform, dense, coating, so strengthening the coating which is formed and improving the high temperature performance of the coatings.

A pre-lubricated stock sheet and a method and system for making the same are described. The pre-lubricated stock is generally in a coil wound form. The stock sheet can have opposing first and second sheet surfaces joined together by opposing side edges and opposing ends. Typically, the first and second sheet surfaces are substantially smooth and planar, wherein the sheet has 3 mg/foot.sup.2/side to about 200 mg/foot.sup.2/side of a solid lubricant having a melting temperature from about 80 to 212 degrees Fahrenheit. Moreover, the opposing side edges usually are substantially free of the solid lubricant. In some configurations, the stock sheet is an aluminum stock sheet, more particularly an aluminum can stock sheet. Furthermore, the lubricant can be in some configurations a food grade lubricant, that is qualifies a low volatile organic compound under one or more of municipal, state and federal governing authorities.
