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.
