Patent ID: 8586520

Claim:
A method of improving the pour point of a lubricating composition comprising a Group III base stock, one or more polyalkylene glycol mono ethers and one or more polymethyacrylate pour point depressants, comprising the step of: premixing at least one polyalkylene glycol mono ether with at least one pour point depressant prior to blending the premixed polyalkylene glycol mono ethers and pour point depressants with the base stock, wherein the one or more polyalkylene glycol mono ethers constitutes from 2.0 to 5.0 wt. % of the lubricating composition and is poly(oxyethlene)(4)laurl ether represented by the formula C 12 H 25 (OCH 2 CH 2 ) 4 OH, wherein the one or more polymethyacrylate pour point depressants constitutes about 0.3 wt. % of the lubricating composition, and wherein the pour point of the lubricating composition is lowered by from 7 to 12° C. relative to the same lubricating composition without said premixing step.
