Abstract:
    The invention relates to a lube base oil which has a high viscosity index and a low pour point. The lube base oil is characterized in that it is constituted substantially of n-paraffins and isoparaffins and that (a) the average number of carbon atoms per molecule, Nc, is 28 to 40 and (b) the average number of branches per molecule, Nb, calculated from the proportion of the CH3 carbon atoms in all carbon atoms which is determined by
