Definitions

  • This invention relates to lubricating oil compositions suitable for use in internal combustion engines. More particularly, this invention relates to a low ash, sulfur, and phosphorous lubricating oil composition.
  • Contemporary lubricants such as engine oils use mixtures of additive components to include numerous performances benefits.
  • additives components include, anti-wear and extreme pressure components, fuel economy improving components, friction reducers, dispersants, detergents, corrosion inhibitors and viscosity index improving additive. These additives provide energy conservation, engine cleanliness and durability and high performance levels to the lubricating oil under a wide range of engine operability conditions including temperature, pressure and lubricant service life.
  • ZnDTP zinc (dialkyl) dithiophosphate
  • ZnDDP zinc (dialkyl) dithiophosphate
  • Sulfur is known to be poisonous to deNox catalysts and zinc phosphates cause plugging of the exhaust particulate filters.
  • SAP sulfur, ash and phosphorous components in oil are commonly referred to as "SAP" or "SAPS" in the art.
  • ZnDTP The major problem with ZnDTP is the poisoning effects to after- treatment devices that may aggravate emission problems.
  • ZnDTP has strong interactions with dispersants, detergents, other anti-wear components and MoDTC causing antagonistic effects on friction, sludge and deposit, if inappropriate concentrations are utilized.
  • Replacing ZnDTP additives is not a simple endeavor because the wear protection demand for today's engine is extremely high and place extremely rigorous chemical limits on any reductions in ZnDTP treat levels.
  • a lubricating oil composition comprises a lubricating oil basestock, a boron-containing additive present in the amount in the range of at least 0.1 weight percent of the composition and less than 8.0 weight percent, a non-corrosive sulfur additive present in the amount in the range of at least 0.1 weight percent of the composition and less than 4.0 weight percent , a dispersant— detergent-inhibitor system of less than 15 percent weight percent of the composition, a zinc dithiophosphate additive present in the amount in the range of at least 0.2 weight percent of the composition and no more than 2.0 weight percent of the composition wherein weight percent is active ingredient weight of the composition.
  • the formulated oil composition having at least 100 and less than 630 PPM phosphorus, at least 1,000 PPM and less than 3,000 PPM sulfur, and at least 105 PPM and less than 710 PPM zinc, at least 80 PPM and less than 450 PPM boron.
  • an additive composition for lubricating oils comprises an organic boron containing additive present in the amount in the range of at least 0.4 weight percent and less than 32 weight percent of the additive, a detergent-dispersant system of less than 60 percent weight percent of the additive, a zinc dithiophosphate additive present in the amount in the range of at least 0.8 weight percent and less than 8.0 weight percent of the additive, a non-corrosive ashless sulfur additive present in the amount in the range of at 0.4 and less than 16.0 weight percent of the additive.
  • a method of obtain a favorable lubricating properties comprises obtaining a composition comprising a lubricating oil basestock, an organic boron containing additive of at least 0.1 and less than 8 weight percent of the composition, a dispersant— detergent- inhibitor system of less than 15 percent weight percent of the composition, zinc dithiophosphate additive of at least 0.2 weight percent of the composition and no more than 2.0 weight percent of the composition, a non corrosive ashless sulfur additive of at 0.1 and less than 4.0 weight percent of the 08946
  • the formulated oil composition having at least 100 and less than 630 PPM phosphorus, at least 1,000 PPM and less than 3,000 PPM sulfur, and at least 105 PPM and less than 710 PPM zinc, at least 80 PPM and less than 450 PPM boron.
  • This invention relates to engine lubricants formulated with unique functional fluids and/or additives to achieve performance improvements.
  • One embodiment is a low SAP engine lubricant composition comprising combinations of organic borates, non-corrosive sulfur compounds, optional high levels of ashless antioxidants, and low levels of ZnDTP to achieve high level of performance equal to or better than using high level of ZnDTP alone.
  • component synergy is built upon a variety of functionalities to achieve well balanced performance features. In a preferred embodiment, these performance features favorably exceed engine oils formulated with high levels of zinc dithiophosphates and metallic detergents.
  • the lubricating oils maintain low frictional properties of film under various operating conditions.

  • non-corrosive, organic sulfur compounds when blended with high levels of organic borates, and low level of zinc dithiophosphates provide substantial property benefits.
