Abstract: A lubricant composition may be used as an engine oil. Such lubricant compositions may, for example, include: from about 25.0 mass % to about 99.8 mass % of an oil base stock, based on a total mass of the lubricant composition, the oil base stock including at least one bio-sourced basestock and at least one alkyl naphthalene; and wherein the lubricant composition includes about 0.05 mass % or less phosphorus, about 0.05 mass % or less sulfur, and about 0.5 mass % or less ash.

Abstract: Provided is an engine oil lubricant composition with improved fuel economy. The engine oil lubricant composition may include 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 that is not a Group IV base oil, where these weight percents are based on the total weight of the engine oil lubricant composition. The engine oil lubricant composition can have 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.
