Title: LUBRICANT BASE STOCK BLENDS
Abstract:
Disclosed is a lubricant base stock blend comprising a PAO base stock and an alkylated aromatics (AA) base stock, wherein at least the longer portion of the pendant groups attached to the carbon backbones of the PAO molecules have comparable length to at least the longer portion of the side chain groups attached to the aromatic ring structure of the AA molecules. The comparable lengths of at least the longer portion of the pendant groups and the side chain groups lead to enhanced improvement in oxidation stability of the blend.
