The present invention is directed to a refrigerator oil composition comprising 

Refrigeration oil from gas-to-liquid-derived and bio-derived triesters

It has been determined that sealant fluid formulations comprising a lubricant oil derived from Fischer-Tropsch waxes demonstrate performance comparable to sealant fluid comprising lubricants derived from polyalphaolefins (PAO's). The sealant fluids of the current invention can provide excellent performance properties similar to those provided by PAO based sealant fluids, but at lower cost.

Formulating a sealant fluid using gas to liquid base stocks

Refrigeration oil from gas-to-liquid derived and bio-derived diesters

A compressor lubricant composition providing energy savings and exhibiting excellent oxidation stability is provided, as well as a process for preparation of the lubricant composition. The composition comprises: (i) from 68 to 99.999 wt % of an isomerized base oil or blend of isomerized base oils; (ii) 0.001 through 20 wt % of a blend of ashless additives, the ashless additives having a viscosity range at 40&#xb0; C. of from 50 mm/s to 60 mm/s, a density at 20&#xb0; C. of from 0.95 through 1.05 g/cm, a flash point of greater than 100&#xb0; C. (COC), solubility in mineral oil of greater than 5 wt %, sulfur content of from 4.8 wt % through 6.0 wt %, and phosphorus content of from 2.9 through 3.6 wt %; (iii) less than 1.0 wt % of a dithiocarbamate, wherein the Conradson carbon residue is less than or equal to 3.00. The dithiocarbamate is added to the base oil blend as a top treatment.
