Abstract
A lubricating oil composition with high thermal stability, corrosion resistance, and extreme-pressure performance is provided. The present invention have been completed by finding that a lubricating oil composition containing a particular primary aliphatic polysulfide has excellent thermal stability and extreme-pressure performance. A lubricating oil composition containing a base oil and an additive agent, wherein an aliphatic polysulfide constitutes as an additive agent 1% to 10% by mass of the lubricating oil composition, and a primary aliphatic polysulfide constitutes 1% to 50% by mass of the aliphatic polysulfide.
