    Abstract: An oxidized olefin wax useful as a pour point depressant for hydrocarbon compositions and/or additive to reduce the wax particle size of wax precipitates in hydrocarbon compositions is described. Method for reducing the pour point and/or wax particle size of hydrocarbon composition with an oxidized olefin wax are described.

    Abstract: Addition of 0.1 to 1.5 percent by weight of wax oxidates to a diesel fuel is found to reduce the amount of soot and invisible particles produced when the fuel is used in a diesel engine. The wax oxidates act synergistically with fuel-soluble organometallic compounds such as alkyl cyclopentadienyl manganese tricarbonyl complex salts in reducing particulates. The wax oxidates used have a ratio of Neutralization Number to Saponification Number below about 0.40 and a Saybolt Universal Viscosity at 210.degree. F. higher than 1600.
