Oxidation behavior of lubrication oils

The literature suggests the following data as empirical values indicating the oxidation stability (Fig. 4-129)  

Evaluation of the oxidation tests on the vacuum distillates showns an increasing oxidation start temperature Tj (point A) and also an increasing maximum temperature of the first peak as a consequence of the rise of the viscosity (Fig. 4-130,4-131). The correspon-
