Provided is an engine oil lubricant composition with improved fuel efficiency. The engine oil lubricant composition may include: a polyalpha olefin base oil component an amount of about 50 wt % to about 90 wt % based on a total weight of the engine oil lubricant composition, wherein the polyalpha olefin base oil component is a Group IV base oil and has a Noack volatility of about 12.5% to about 15%; a Group II base oil component in an amount of about 0.1 wt % to about 50 wt % based on the total weight of the engine oil lubricant composition. The engine oil lubricant composition may have (i) a kinematic viscosity at 100° C. of about 10 cSt or less, (ii) a high temperature high shear viscosity at 150° C. of about 2.2 cP or less, and (iii) a Noack volatility of about 20% or less.

Non-newtonian engine oil lubricant compositions for superior fuel economy

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&#xb0; 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&#xb0; C. of 6 cSt or less, an HTHS (ASTM D4683) of less than or equal to 2.2 cP at 150&#xb0; C. and a FZG failure load stage of at least 6, as measured by the FZG A10/16.6R/130 test procedure.

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

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&#xb0; C. Also provided are methods of using the lubricant composition in internal combustion engines and methods of making the lubricant composition.
