Lubricant compositions are described, capable of providing high performances in internal combustion engines, comprising:
(a) from 50 to 90% by weight of Group II (API) base oils having a volatility comprised between 7.0 and 10.0% by weight and a viscosity index comprised between 110 and 119;
(b) from 10 to 50% by weight of additives selected from antioxidants, anti-wear, detergents, dispersants, viscosity index modifiers, pour point depressants, antifoaming agents, friction modifiers or friction reducers. The use of these lubricant compositions as engine oil for automotive applications is also described. |
