Provided herein are hydrocarbon compositions suitable for use as a lubricant comprising sulfur between about 30 ppm to about 220 ppm, and aromatics between about 0.2 wt. % to about 3 wt. %. The present hydrocarbon compositions comprise a blend of one or more base stocks and a high-sulfur containing material and can demonstrate an improved oxidation performance as a lubricant in weighted piston deposit merits and/or by viscosity increase.

Hydrocarbon compositions useful as lubricants for improved oxidation stability

Systems and methods are provided for co-processing of used lubricant oils with a coker feedstock in a fluidized coking process to form lubricant base stocks. The fluidized coking process can remove contaminants and/or additives from used lubricant oils with modest conversion of the lubricant boiling range portion.

Lubricant base stock production from recycled oil

Rapid determination of low temperature residual wax contamination in basestock oil provides a basis for real time correlation of basestock quality with the low temperature viscometric properties of fully formulated oils made using said basestock oil.
