The thin film oxidation resistance of isoparaffin and two polyol esters synthetic lubricants was studied by high pressure differential scanning calorimetry. The oxidation induction time of each lubricant was measured by isothermally heating the sample in an oxygen environment. Arrhenius plots were constructed to predict the service life of the lubricant at low temperatures. The results indicate that polyol esters exhibit better oxidative stability than isoparaffins.
