    Abstract: This invention relates to low-sulfur diesel fuels which are useful with diesel engines equipped with exhaust system particulate traps. These fuels contain an effective mount of an organometallic complex to lower the ignition temperature of exhaust particles collected in the trap. The sulfur content of these diesel fuels is no more than about 0.1% by weight, preferably no more than about 0.05% by weight. The organometallic complex is soluble or stably dispersible in the diesel fuel and is derived from (i) an organic compound containing at least two functional groups attached to a hydrocarbon linkage, and (ii) a metal reactant capable of forming a complex with the organic compound (i), the metal being any metal capable of reducing the ignition temperature of the exhaust particles. The functional groups include =X, -XR, -NR2, -NO2, =NR, =NXR, =N-R*-XR, -CN, -N=NR and -N=CR2; wherein X is O or S, R is H or hydrocarbyl, R* is hydrocarbylene or hydrocarbylidene, and a is a number (e.g., zero to about 10). Useful metals include Na, K, Mg, Ca, Sr, Ba, Ti, Zr, V, Cr, Mo, Mn, Fe, Co, Cu, Zn, B, Pb, Sb, and mixtures of two or more thereof. This invention is also directed to methods of operating a diesel engine equipped with an exhaust system particulate trap using the foregoing low-sulfur diesel fuels.

    Abstract: A liquid extreme pressure agent for use in lubricating compositions where the lubricating compositions comprise an oil of lubricating viscosity and the reaction product of: (a) a thiazole; (b) a composition comprising a carboxylic acid, a phosphorus containing acid or salt, or combinations thereof; and (c) an amine containing one or more branched hydrocarbyl groups. The invention also provides an additive composition comprising the reaction product described above and a process for making lubricating compositions, including greases, from the reaction product.

    Abstract: The disclosed invention relates to a biodegradable grease composition. The grease composition comprises the reaction product of a dispersion of metal oxide and/or hydroxide particulates with at least one animal or vegetable oil. The dispersion comprises an organic medium and has a water content of up to about 0.5% by weight water. The particulates have a mean particle size up to about 15 microns. A process for making a grease composition using a dispersion of metal oxide and/or hydroxide particulates is disclosed.
