Abstract (en)
[Problem to be solved] To provide a lubricating oil composition for a supercharged engine, which is capable of having a good balance of caulking resistance, LSPI suppression performance, and high-temperature cleaning properties.[Means to solve the problem] The lubricating oil composition for a supercharged engine according to the present invention is characterized by comprising:(A) a lubricating oil base oil;(B) a calcium-based cleaning agent, wherein the calcium amount is 1100 mass ppm or more to 1900 mass ppm or less on a total amount basis of the lubricant composition;(C) a magnesium-based cleaning agent; and(D) at least one viscosity index improver selected from a styrene-diene copolymer and an ethylene-α-olefin copolymer; and(E) a nitrogen-containing dispersing agent;and containing 700 mass ppm or more of nitrogen component, on a total amount basis of the lubricating oil composition.
