Determination of the oxidation stability of motor oil

Motor oils are exposed to high shear forces and temperatures while the motor is running. Mechanical abrasions set iron and copper free, which acts as catalysts for oxidation. All this decrease the durability of motor oils. The oxidation stability with iron and copper catalysts can give an approximately indication for the shelf life. A reproducible and accurate determination of the oxidation stability using the 892 Professional Rancimat can be realized.
