A lubricant composition is provided comprising a major amount by weight of a lubricant having dispersed therein a minor amount by weight of added abrasive particles having a hardness on the Mohs scale of at least 9, the abrasive particles having a size distribution such that the average particle size is less than 2 microns and the maximum particle size is less than 3 microns. When used as a lubricant for, for example vehicle engines and gear boxes, substantial economies in fuel consumption are obtainable. |
