Abstract (en)
The present invention relates to a lubricant composition comprising at least one oil-soluble organic molybdenum compound and at least one oil-soluble tungsten compound, with the proviso that the weight ratio of molybdenum to tungsten in the lubricant is at least 2.5:1. The compositions provide unexpected and substantially improved friction and abrasion properties over related compositions devoid of the invention. When using these lubricant compositions, for example in internal combustion engines, the engine power can be increased and the fuel consumption can be reduced.
