Abstract: A lubricating oil composition that includes a highly paraffinic base oil, a controlled release friction modifier (CRFM) and an effective amount of detergent. The CRFM includes an ionic tetrahedral borate compound comprising a cation and a tetrahedral borate anion which includes a boron atom, the boron atom having two bidentate di-oxo ligands of C18 tartrimide. The CRFM is a high stabilizer CRFM. The detergent includes a mixed magnesium and calcium detergent system having a calcium to magnesium ratio of less than 2:1.

Abstract: A lubricant composition includes a lubricating base oil, a controlled release friction modifier, a dispersant, a viscosity modifier and a cleanliness booster. The controlled release friction modifier is an ashless, dispersant-stabilized, borated controlled release friction modifier including an ionic tetrahedral borate compound including a cation and a tetrahedral borate anion, wherein the tetrahedral borate anion includes a boron atom having two bidentate di-oxo ligands of C18 tartrimide.

Abstract: A lubricant base oil is provided. The lubricant base oil has a low temperature property determined using a stepwise regression of carbon-13 nuclear magnetic resonance (NMR) spectroscopy peak values. A method of selecting candidate lubricant base oils, or mixtures thereof, having acceptable low temperature performance is also provided. An online method of blending a lubricant base oil and a finished lubricant are also provided.
