Abstract:
A lubricating oil composition for an internal combustion engine including: (A) a lubricant base oil having a kinematic viscosity at 100° C. of 2 to 8 mm 2 /s and having an aromatic content of no more than 10 mass %; (B) a metallic detergent including: (B1) a metallic detergent overbased with calcium carbonate; and (B2) a metallic detergent overbased with magnesium carbonate; and (C) a molybdenum sulfide dithiocarbamate or a molybdenum oxysulfide dithiocarbamate, wherein the composition has, on the basis of the total mass of the composition, a calcium content of no more than 1500 mass ppm, a magnesium content of no less than 300 mass ppm, and a molybdenum content of no less than 600 mass ppm; and the composition has an HTHS viscosity at 150° C. of no more than 2.7 mPa·s.

Claim (Index 1):
A lubricating oil composition for an internal combustion engine comprising:\n (A) a lubricant base oil having a kinematic viscosity at 100\u00b0 C. of 2 to 8 mm 2 /s and having an aromatic content of no more than 10 mass %; (B) a metallic detergent comprising:\n (B1) a metallic detergent overbased with calcium carbonate; and \n (B2) a metallic detergent overbased with magnesium carbonate; and \n (C) a molybdenum sulfide dithiocarbamate or a molybdenum oxysulfide dithiocarbamate, wherein the composition has a calcium content of 1400 to 1500 mass ppm on the basis of the total mass of the composition; the composition has a magnesium content of 350 to 600 mass ppm on the basis of the total mass of the composition; the composition has a molybdenum content of no less than 600 mass ppm on the basis of the total mass of the composition; the composition has a boron content of 200 to 300 mass ppm on the basis of the total mass of the composition; the composition has an HTHS viscosity at 150\u00b0 C. of no more than 2.7 mPa\u00b7s, and the composition has a parameter r s \u2032 represented by the following mathematical formula (2) of 1.15 to 1.50:\n r s \u2032=([S]\u2032+[Mo]+[Zn])/([Mg]+2\u00d7[Ca])\u2003\u2003(2) \n wherein in the mathematical formula (2), [S]\u2032 represents a sulfur content derived from additives other than any sulfonate detergent (unit: mass ppm); [Mo] represents the molybdenum content of the composition (unit: mass ppm); [Zn] represents a zinc content of the composition (unit: mass ppm); [Mg] represents the magnesium content of the composition (unit: mass ppm); and [Ca] represents the calcium content of the composition (unit: mass ppm).
