Abstract (en)
[origin: CA2390229A1] A method for blending base oils for use in passenger car motor oils. The PCM Os blended from these base oils show improved volatility and fuel economy, whil e maintaining current engine durability/wear protection and providing improved low temperature performance. For a 10W base oil, the method comprises blendi ng a base oil wherein said base oil has a viscosity index greater than about 10 0, a finished oil Noack volatility less than about 15%, a finished oil Cold Cranking Simulator value at -20~C of less than about 2500 cP, and a base oil kinematic viscosity at 100~C of from about 5.0 to about 6.0 cSt. For a 5W ba se oil, the method comprises blending a base oil wherein said base oil has a viscosity index greater than about 100, a finished oil Noack volatility less than or equal to about 15%, a finished oil Cold Cranking Simulator value at - 25~C of less than about 2500 cP, and a base oil kinematic viscosity at 100~C of from about 4.0 to about 5.0 cSt.
