ABSTRACT:
An oxidation-resistant hydrocarbon oil composition is made by catalytically hydrogen-refining under relatively severe conditions a hydrocarbon oil basestock boiling in the lube oil boiling range and separately catalytically hydrogen-refining under relatively mild conditions a hydrocarbon fraction boiling in the lube oil range and having an aniline point exceeding 60.degree. C. and a sulfur content of at least 2.0 wt %. The resulting severely-refined basestock has a sulfur content not greater than 0.10 wt % and the resulting mildly-refined fraction has a sulfur content of at least 1.0 wt %, and the desired oxidation resistant composition is a blend comprising 85 to 99.9 wt % of the former and 15 to 0.1 wt % of the latter.
