  • Publication number: 20030119682
    Abstract: An engine lubricant formulated as a complete crankcase motor oil or additive concentrate composed of a combination of chemical constituents including a base oil selected from a synthetic oil, a mineral oil or semi-synthetic base oil (hydrogenated oil) or combination thereof, an oil soluble molybdenum additive, a dispersant inhibitor containing zinc dithiophosphate, and viscosity index improvers and one or more seal swelling agents to lubricate the engine and recondition the seals of new and/or high mileage engines. Addition of a polyalphaolefin and/or one or more esters such as a diester or polyolester may also be utilized therein. The lubricant may be formulated as a complete engine oil crankcase lubricant, or concentrated into an additive for addition to conventional mineral oil based engine oil, synthetic engine oils, or blends thereof in an effective amount of up to 30 percent volume percent, typically from 20 to 25 percent by volume.

  • Publication number: 20030087769
    Abstract: A lubricant additive formulation for increasing the performance of conventional engine lubricants for use as an engine treatment oil additive formulated for addition to conventional motor oil to improve the lubricating properties of the engine oil and enhance the performance of the engine. A preferred embodiment of the engine treatment oil additive comprises a blend of chemical constituents including a base stock selected from a synthetic base stock, a mineral oil base stock, and a severly hydrocracked base stock or combinations thereof, an oil soluble molybdenum additive, dispersant inhibitor, and selected additives such as polytetrafluoroethylene, viscosity index improvers, and extreme pressure wear agent used in combination with a conventional crankcase lubricant at about a 20 to about a 25% volume/percent or as a complete motor oil. Additional components may be added to the engine treatment oil additive formulation to enhance specific properties for special applications.

  • Publication number: 20020077377
    Abstract: This invention relates generally to water resistant peelable protective and decorative clear or pigmented foam coating compositions and, more specifically, to aqueous and solvent based, polymeric coating compositions which form a protective and/or decorative coating and is removably adheres to a variety of substrates, including automotive paints, metals, glass, vinyl, plastics, concrete, natural and synthetic elastomers, and ceramics. The coatings present a three-dimensional expandable foamy coating, and can be readily peeled off from the substrate as a whole piece. The coatings may be formulated for temporary or long-term protection depending upon the application.

  • Publication number: 20020030177
    Abstract: The present invention relates to a carboxylic acid based antifreeze coolant formulation for heavy duty applications such as for diesel engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, low levels of molybdates, a nitrite salt and/or nitrate salt and/or siloxane stabilized silicate, and combinations thereof, polyvinylpyrrolidone, provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges.

  • Patent number: 5763369
    Abstract: According to the invention, combining some or all of the following components: oil soluble Molybdenum additive (Molyvan 855--Vanderbilt Chemical); ("Synthetic") polyalphaolefin (PAO) 4 cSt; PAO 6 cSt and/or synthetic diester (e.g., Chemaloy M-22A); PTFE (polytetrafluoroethylene colloidal dispersed product--Acheson Chemical) Dispersant Inhibitor (DI) package containing zinc dithiophosphate (ZDP), etc., (Chemaloy D-036); Mineral Oil Base Stock; Viscosity Index Improver (VI) (Shellvis 90-SBR); into a package for addition to conventional motor oil results in improved wear, oxidation resistance, viscosity stability, engine cleanliness, fuel economy, cold starting, and inhibited acid formation. It has been discovered that when added to the crankcase of an internal combustion, e.g., spark ignition (SI) engine at most preferably approximately 20-25 vol. % with the conventional crankcase lubricant, this provides synergistic performance improvement of the oil and engine.
