Method for producing heavy and light lubricating base oil

摘要

The invention is directed to a lubricant formulation comprising a base oil having a kinematic viscosity at 100 °C of above 15 cSt, a pour point of below +10 °C and a viscosity index of between 140 and 200 and no viscosity modifier and the use of a viscosity modifier-free lubricant as motor engine lubricant in a gasoline direct injection engine.
