Engine oil lubricant compositions and methods for making same with superior engine wear protection and corrosion protection

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.
