- Polybutenylsuccinic bisimide which is not a borated material, a hindered phenol-based antioxidant, a diphenylamine-based antioxidant, a pour-point depressant, a metal deactivator, and an antifoaming agent
- the HTHS viscosity at 150°C of the lubricating oil composition was measured.
- the friction coefficient of the lubricating oil composition was measured under the following conditions. A lower friction coefficient may indicate that the friction-reducing effect is superior and the fuel consumption reducing properties are better.
- [mass% of Mo] represents the content of the molybdenum compound (B) as converted into molybdenum atoms based on the total amount of the lubricating oil composition
- [mass% of B] represents the content of the borated succinimide (D) as converted into boron atoms based on the total amount of the lubricating oil composition
- [mass% of Metal] represents the content of the metal-based detergent (F) as converted into metal atoms (calcium atoms) based on the total amount of the lubricating oil composition.
- the examples marked with "*" are reference examples.
- the lubricating oil compositions of Examples 1 and 2 each including the molybdenum compound (B), and a specific amount of the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2), exhibit a better friction-reducing effect, as compared with the lubricating oil composition of Comparative Example 1, not including the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2).
- the lubricating oil composition of Comparative Example 2 including more than an appropriate amount of the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2) does not exhibit a good friction-reducing effect.
- the reason for this may be thought to be that the friction-reducing effect of the molybdenum compound (B) is inhibited by a large amount of the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2).
- the ester-based ashless friction modifier (C1) is used in combination with the amine-based ashless friction modifier (C2), but the friction coefficient increases.
- the reason for this may be thought to be that in Comparative Example 3, the total amount of the ester-based ashless friction modifier (C1) and the amine-based ashless friction modifier (C2) is more than 1.8 mass% based on the total amount of the lubricating oil composition, so that the friction-reducing effect of the molybdenum compound (B) is inhibited.
- Example 10 Composition Lubricating base oil (A) mass% Balance Balance Molybdenum compound (B) mass% 0.7 0.7 Ester-based friction modifier (C1) mass% 0.5 0.5 Amine-based friction modifier (C2) mass% 0.1 0.1 Borated succinimide (D) mass% 2.3 - Poly(meth)acrylate (E) mass% 10.3 12.0 Metal-based detergent (F) mass% 1.65 1.65 Zinc dithiophosphate (G) mass% 1.14 1.14 Other components mass% 6.16 6.16 Properties Content of molybdenum derived from (B) mass% of Mo 0.070 0.070 Content of boron derived from (D) mass% of B 0.030 - Content of metal derived from (F) mass% of metal 0.200 0.200 HTHS viscosity at 150°C mPa ⁇ s 2.6 2.6 Evaluation Friction coefficient - 0.051 0.059
- the lubricating oil composition of Example 6 including the molybdenum compound (B), the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2), and the borated succinimide (D) exhibits a better friction-reducing effect, as compared with the lubricating oil composition of Example 10, including the molybdenum compound (B), the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2), but not including the borated succinimide (D).
- the reason for this may be thought to be that in the lubricating oil composition of Example 6, by using the molybdenum compound (B), and the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2), together with the borated succinimide (D), a friction-reducing effect based on the molybdenum compound (B) is more easily retained, and by the synergistic action with the molybdenum compound (B), and the ester-based ashless friction modifier (C1) and/or the amine-based ashless friction modifier (C2), the friction-reducing effect is more enhanced.
- the lubricating oil composition of the present embodiment exhibits a good friction-reducing effect, and thus, the fuel consumption reducing properties can be enhanced. For this reason, the lubricating oil composition of the present embodiment can be suitably used for a variety of internal combustion engines of a four-wheel automobile, a two-wheel automobile, or the like. Further, among the internal combustion engines, the lubricating oil composition of the present embodiment can be particularly suitably used for a gasoline engine.
