  The invention addresses a problem of providing a lubricating oil composition for gas engines capable of suppressing viscosity increase while reducing a sulfated ash content and excellent in high-temperature detergency and base number retention. The lubricating oil composition is used for gas engines and contains a base oil (A), at least one ash-free additive (B) selected from an ash-free sulfur-based antioxidant (B1) and a hindered amine compound (B2), and a boronated imide-type dispersant (C), and satisfies the following requirements (X1) to (X3): Requirement (X1): the sulfated ash content is 0.2% by mass or less. Requirement (X2): the content of the ash-free additive (B) is 1.2% by mass or less based on the total amount of the lubricating oil composition, provided that in the case where the ash-free additive (B) contains the hindered amine compound (B2), the content of the hindered amine compound (B2) is less than 1.0% by mass based on the total amount of the lubricating oil composition. Requirement (X3): the content of the boron atom derived from the boronated imide-type dispersant (C) is 200 ppm by mass or more based on the total amount of the lubricating oil composition.

  本发明要解决的问题是提供一种用于燃气发动机的润滑油组合物，该组合物能够在降低硫酸盐灰分含量的同时抑制粘度增加，并具有优异的高温清净性和基数保持性。该润滑油组合物用于燃气发动机，包含基础油 (A)、至少一种无灰添加剂 (B)（选自无灰硫基抗氧化剂 (B1) 和受阻胺化合物 (B2)）以及硼酸亚胺型分散剂 (C)），并满足以下要求 (X1) 至 (X3)：要求 (X1)：硫酸盐灰分含量不超过 0.2%（按质量计）。要求 (X2)：以润滑油组合物的总量为基准，无灰添加剂 (B) 的质量含量为 1.2% 或更少，但如果无灰添加剂 (B) 中含有受阻胺化合物 (B2)，则以润滑油组合物的总量为基准，受阻胺化合物 (B2) 的质量含量低于 1.0%。要求 (X3)：硼化亚胺型分散剂 (C) 中的硼原子含量为润滑油组合物总量的 200 ppm 或以上（以质量计）。

  To provide a lubricating oil composition that has good detergency irrespective of the small sulfated ash content thereof, and has a good friction reducing capability even after the deterioration thereof. The lubricating oil composition contains a base oil (A), a non-metal-containing sulfur antioxidant (B), and a hindered amine antioxidant (C) having one piperidine-derived skeleton in a molecule, and has a content of the non-metal-containing sulfur antioxidant (B) as converted in terms of sulfur atom of 800 ppm by mass or more based on the total amount of the lubricating oil composition, a content of the hindered amine antioxidant (C) as converted in terms of nitrogen atom of 100 ppm by mass or more and 400 ppm by mass or less based on the total amount of the lubricating oil composition, a sulfated ash content of 0.70% by mass or less, and a total base number of 4.0 mgKOH/g or more.
