Title: TWO-STROKE CYCLE LUBRICANT AND METHOD OF USING SAME of the Invention A lubricant composition suitable for fuel injected two-stroke cycle engines includes an oil of lubricating viscosity, an amount, sufficient to reduce or prevent piston scuffing, of a mixture of (A) at least one phenol selected from (A-1) an aminophenol and (A-2) a reaction product of a nitrophenol and an amino compound, and (B) at least one Mannich dispersant, amine dispersant, nitrogencontaining carboxylic dispersant, or ester dispersant. The composition further includes an amount, sufficient to reduce degradation of the lubricant composition upon exposure to oxygen or oxides of nitrogen, of a nitrogencontaining inhibitor, a hindered phenol inhibitor, or a sulfur-containing organic inhibitor.
