Abstract (en)
Described herein is a method for estimating the residual life of the lubricating oil of an internal-combustion engine, in which there are determined; at least one recapitulatory quantity (30) summarizing the conditions of use of the engine from the last oil change; and at least one quantity (70) indicating the quality of the lubricating oil on the basis of said recapitulatory quantity (30), and in which the residual life (130) of the lubricating oil is estimated on the basis of said quantity indicating the quality of the lubricating oil.
