Abstract:
The lubricating oil composition of the invention comprises a lubricating base oil with a urea adduct value of no greater than 4% by mass and a viscosity index of 100 or higher, an ashless friction modifier at 0.01-10% by mass and a phosphorus-containing anti-wear agent at 0.01-0.2% by mass as phosphorus, based on the total amount of the composition.
