Engine oil lubricant compostions and methods for making same with superior oil consumption

An engine oil lubricant composition comprising:

• about 40 wt % to about 80 wt % of a first oil base stock consisting of a Group IV base oil, and
• about 10 wt % to about 40 wt % of a second oil base stock comprising a Group II base oil, where the weight percents are based on the total weight of the engine oil lubricant composition,
• wherein the engine oil lubricant composition has an HTHS (ASTM D4683) of less than or equal to 2.2 cP at 150° C., a Noack volatility (ASTM D5800) of 25% or less, and an evaporation rate of 6% or less as measured by distillation method DIN 51454 mod. C17-C19.
