Abstract:
PROBLEM TO BE SOLVED: To provide a lubrication oil composition for a heavy duty diesel engine and improved in suitability to a catalytic after-treatment device especially to an after-treatment device including an oxidation and/or reduction catalyst and simultaneously satisfies API-CI-4 standard. SOLUTION: The lubricating oil composition has TBN (total base number) of at least about 8 and comprises (a) a large amount of lubricating viscous oil; (b) one or more dihydrocarbyl dithiophosphate metal salt with no more than 0.06mass% of phosphorus to be introduced into the lubricating oil composition; (c) at least 1.2mass% of a hindered phenol antioxidant; and (d) boron and/or a boron-containing compound in an amount providing the lubricating oil composition with at least 200ppm by mass of boron.

Abstract:
PROBLEM TO BE SOLVED: To provide an additive for engine oil excellent in effect of improving the lubrication performance of the engine oil, and the engine oil added with such the additive for the engine oil, and also a method for adding the additive for improving the lubrication performance of the engine oil. SOLUTION: The additive for the engine oil is constituted by blending a plurality of many sided plate-formed silver crystalline particles having a 300 to 500 nm mean length. Also, the engine oil is constituted by blending base oil with the additive for the engine oil. Further, the method for adding the additive to the engine oil includes adding the plurality of many sided plate-formed silver crystalline particles having the 300 to 500 nm length to the engine oil, as the additive.
