Process for the preparation of two or more types of base oil, engine oil, car passenger, base oil, and use of the oil base.Process for the preparation of two or more types of base oil, base oil, these types have different kinematic viscosities 100 198 C,From a waxy paraffinic Fischer Tropsch product having a content of ISO paraffins cyclical not greater than 70% by weight,By means of (a) obtaining the product of Fischer Tropsch waxy paraffinic fraction distilled a which has a viscosity that corresponds to one of the products of the desired base oil.(b) carry out a step of removing wax catalytic using distilled fraction obtained in step (a) as a food.(c) separating the compounds with lower boiling points of the product with the wax removed obtained in step (b) with the purpose of obtaining the desired base oil.And (d) repeating steps (a) - (c) for each base oil.
