Abstract: Provided is a non-Newtonian engine oil lubricant composition with improved fuel efficiency and engine wear protection. The lubricant composition includes a major amount of a base oil including a Group II base stock and an optional Group V base stock, from 0.1 to 9.0 wt. % of at least one viscosity modifier and from 0.1 to 1.2 wt. % of at least one friction modifier. The non-Newtonian engine oil lubricant composition has a kinematic viscosity at 100 deg. C. of less than or equal to 10 cSt and an HTHS (ASTM D4683) of less than or equal to 2.2 cP at 150° C. Also provided are methods of using the lubricant composition in internal combustion engines and methods of making the lubricant composition.

Abstract: Provided is an engine oil lubricant composition with improved fuel efficiency and engine wear protection. The lubricant composition may include a major amount of an oil basestock from any one or more Group I, Group II, Group III, Group IV or Group V base oils. The resulting engine oil lubricant composition may have a kinematic viscosity at 100° C. of 6 cSt or less, and a corrosion protection of at least 90, as measured according the ASTM D6557 Ball Rust Test. The resulting engine oil lubricant composition may also have a kinematic viscosity at 100° C. of 6 cSt or less, an HTHS (ASTM D4683) of less than or equal to 2.2 cP at 150° C. and a FZG failure load stage of at least 6, as measured by the FZG A10/16.6R/130 test procedure.
