Degradation of lubricating oil is roughly classified into two types, one is caused by solid particles and the other is caused by oil oxidation products. Diagnosis methods for solid particles in lubricating oils have many standards and research. However, there are few diagnosis methods for the oil oxidation products. In the present work, I developed new method to evaluate a little difference of the contamination level of lubricating oils, especially for oxidation products. The relation between reflectance of the membrane patch made transparent using degradation oils, which were used in actual machines, were investigated with a spectrophotometer. As a result, I could distinguish and evaluate a little difference of the contamination level of lubricating oils by measuring the reflectance of the membrane patch in the face side and the back side.
