Abstract: A method for improving 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 includes at least one lubricating oil base stock having one or more liquid crystals represented by the formula: R1 - (A) m - Y - (B) n - R2 wherein R1 and R2 are the same or different and are a substituted or unsubstituted, hydrocarbon, alkoxy or alkylthio group having from 2 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-, -CH=CH-, -C≡C-, -OCOO-, -CO-, -CSO-, -CSS-, -CS-, -O-, -S-, -SO-, -SO2-, -CH2O-, -OCH2O-, -NO-, -ONO2, or -C≡N; and m and n are independently 0, 1, 2 or 3. The lubricating oil base stock has a kinematic viscosity of 2 cSt to 200 cSt at 40°C, and 1 cSt to 25 cSt at 100°C. Also, this disclosure relates to low traction/energy efficient liquid crystal base stocks containing liquid crystals.

Abstract: 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) 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.
