Latest Patents

Among his latest patents, one notable invention is the development of low ash lubricant compositions for internal combustion engines. This invention provides low sulfated ash lubricating oil compositions that include an oil of lubricating viscosity as the major component. The minor components consist of at least about 2 wt % of an ashless nitrogen- or ester-containing dispersant, an effective amount of at least one oil-soluble antioxidant material, and at least one oil-soluble dihydrocarbyl dithiophosphate antiwear material. The lubricating oil is characterized by a total sulfated ash (SASH) level ranging from 0.01 to about 0.6 wt % and a SASH wt:dispersant wt ratio of about 0.01 to about 0.2:1.

Another significant patent involves lubricant compositions for internal combustion engines, which also feature low sulfated ash lubricating oil compositions. This invention includes an oil of lubricating viscosity as the major component and at least about 3 wt % of an ashless nitrogen- or ester-containing dispersant as a minor component. Additionally, it incorporates at least about 2 wt % of a sulfurized alkyl phenol and at least one metal dihydrocarbyl dithiophosphate. The lubricating oil in this patent is similarly characterized by a total sulfated ash (SASH) level of from 0.01 to about 0.6 wt % and a SASH:dispersant wt:wt ratio of from about 0.01 to about 0.2:1.
