This invention provides a method for improving the physico-chemical and usage properties of an existing lubricant, of a solid or liquid consistency, such as gear oils, engine oils and all-purpose oils. The method is based on complementing the composition of the existing lubricant with a mixture of several solid substances (thickeners), in an amount varying from 5 to 35 weight percent of the initial existing lubricant. As a result of their addition, a considerable improvement in a number of the lubricant's properties is achieved. For example, an increase in saturation load, as measured on a 4-ball apparatus of 1600 N to 3150 N; improved friction coefficient μ, the wear scar under 600 N load, and more. Using the method specified in the invention, it is possible to make significant improvements to the quality of a lubricant at relatively low cost. 1.
