Abstract: An engine lubricant, especially an SAE OW engine lubricant is described. The engine lubricant has at least 15 wt% of at least one diester and not more than 15 wt% of additives, wherein said at least one diester, or mixture of said diesters if more than one is present, has a kinematic viscosity at 100° C of not more than 3.3, a viscosity index of at least 130, a pour point of not more than -30° C and a Noack evaporation loss of not more than 15 wt%.
