PROBLEM TO BE SOLVED: To provide a cylinder lubricant composition for cross heat type diesel engine capable of enhancing demulsibility of a cylinder oil for cross heat type diesel engine and reducing or suppressing generation a hydrocarbon-based material, sin and scum from water in a scrubber.SOLUTION: There is provided a cylinder lubricant composition for cross heat type diesel engine with a scrubber containing a base oil, (A) a Ca phenate cleaner and (B) a metallic cleaner other than the a phenate cleaner and having basic value of 15 to 125 mgKOH/g, kinetic viscosity of 10 to 30 mm/s at 100°C and pH value represented by the following formula (1) of 20×10or less. pH value=C×2/(r×40.08) (1), where Crepresents the content of calcium derived from the (A) component (mass%) and rrepresents a metal ratio of the (A) component.SELECTED DRAWING: None |
