ABSTRACT:
A blended mineral oil lubricant is made having a higher viscosity index than predicted by calculating the viscosity index from an ASTM standard method designated D 341-87 or by calculating the average of the actual VI based on the proportion of each component of the blend. The lubricant is treated with a peroxide compound, preferably an organic peroxide such as di-tertiary butyl peroxide to increase the viscosity index. The treated lubricant is blended with a lubricant of lower viscosity index to achieve a blended lubricant having an enhanced viscosity index. The lubricant charge stock and blending component can be a wax-derived lubricant fraction or a conventional light neutral or heavy neutral mineral oil.
