Lubricating oil compositions comprising a biodiesel fuel and a Mannich condensation product

This invention encompasses lubricating oil compositions comprising a base oil, a biodiesel fuel and a dispersant. A method for inhibiting viscosity increase in a diesel engine fueled at least in part with a biodiesel fuel is also described.

Lubricating oil compositions comprising a biodiesel fuel and a dispersant

A lubricating oil composition having a sulfated ash content of from greater than 1.0 wt. % to about 2.0 wt. %, a phosphorus content of from about 0.07 to about 0.12 wt. % and a sulfur content of 0.4 wt. % or less, the lubricating oil composition comprising: (a) an oil of lubricating viscosity in a major amount; (b) an overbased magnesium detergent, in an amount providing the lubricating oil composition with at least 600 ppm of magnesium; (c) a boron-containing compound, in an amount providing the lubricating oil composition with at least 250 ppm of boron; and (d) a molybdenum-containing compound, in an amount providing the lubricating oil composition with at least 50 ppm of molybdenum, wherein the composition has a B/Mo mass ratio in a range of 2 to 10 and a S/Mo mass ratio in a range of 10 to 25.
