Definitions
- the present invention relates to automotive lubricating oil compositions, more especially to automotive lubricating oil compositions for use in piston engines, especially gasoline (spark-ignited) and diesel (compression-ignited) internal combustion engines, crankcase lubrication, such compositions being referred to as crankcase lubricants.
- the present invention relates to automotive lubricating oil compositions for use in gasoline (spark-ignited) and diesel (compression-ignited) internal combustion engines fuelled at least in part with a biofuel, especially compression-ignited internal combustion engines fuelled at least in part with a biodiesel fuel and spark-ignited internal combustion engines fuelled at least in part with bioethanol fuel.
- the present invention relates to automotive lubricating oil compositions, preferably having low levels of phosphorus and also low levels of sulfur and/or sulfated ash, which exhibit an improved inhibition and/or a reduction in the corrosion of the metallic engine parts; and to the use of additives in such compositions for improving the anti-corrosion properties of the lubricating oil composition.
- a crankcase lubricant is an oil used for general lubrication in an internal combustion engine where an oil sump is situated generally below the crankshaft of the engine and to which circulated oil returns.
- Biodiesel fuels include components of low volatility which are slow to vaporize after injection of the fuel into the engine. Typically, an unburnt portion of the biodiesel and some of the resulting partially combusted decomposition products become mixed with the lubricant on the cylinder wall and are washed down into the oil sump, thereby contaminating the crankcase lubricant.
- the biodiesel fuel in the contaminated lubricant may form further decompositions products, due to the extreme conditions during lubrication of the engine. It has been found that the presence of biodiesel fuel and the decomposition products thereof in the crankcase lubricant promotes the corrosion of the metallic engine parts; particularly the softer metallic (i.e.
- Exhaust gas after-treatment devices such as a diesel particulate filter (DPF)
- DPF diesel particulate filter
- One way to create conditions for initiating and sustaining regeneration of a DPF involves elevating the temperature of the exhaust gases entering the DPF to burn the soot. As a diesel engine runs relatively cool and lean, this may be achieved by adding fuel into the exhaust gases optionally in combination with the use of an oxidation catalyst located upstream of the DPF.
- Heavy duty diesel (HDD) engines such as those in trucks, typically employ a late post-injection of fuel directly into the exhaust system outside of the cylinder, whilst light duty and medium duty diesel engines typically employ a late post-injection of fuel directly into the cylinder during an expansion stroke.
- the corrosion of the softer metallic (i.e. non-ferrous) engine components increases significantly in a diesel engine fuelled at least in part with biodiesel when the engine employs a late post-injection of fuel directly into the cylinder.
- this increased engine corrosion is due to more biodiesel being absorbed by the lubricant on the more exposed cylinder wall, thereby increasing contamination of the lubricant in the sump.
- an alcohol based fuel e.g. bioethanol
- lubricating oil compositions which exhibit improved anti-corrosion properties in respect of the metallic engine components, particularly the softer metallic (i.e. non-ferrous) engine components such as those containing copper and/or lead (e.g. bearing materials), must be identified.

- the oil of lubricating viscosity (sometimes referred to as “base stock” or “base oil”) is the primary liquid constituent of a lubricant, into which additives and possibly other oils are blended, for example to produce a final lubricant (or lubricant composition).
- a base oil is useful for making concentrates as well as for making lubricating oil compositions there from, and may be selected from natural (vegetable, animal or mineral) and synthetic lubricating oils and mixtures thereof. It may range in viscosity from light distillate mineral oils to heavy lubricating oils such as gas engine oil, mineral lubricating oil, motor vehicle oil and heavy duty diesel oil. Generally, the viscosity of the base stock will have a viscosity preferably of 3-12, more preferably 4-10, most preferably 4.5-8, mm 2 /s (cSt) at 100°C.
- Natural oils include animal and vegetable oils (e.g. castor and lard oil), liquid petroleum oils and hydrorefined, solvent-treated mineral lubricating oils of the paraffinic, naphthenic and mixed paraffinic-naphthenic types. Oils of lubricating viscosity derived from coal or shale are also useful base oils.

- Unrefined, refined and re-refined oils can be used in the compositions of the present invention.
- Unrefined oils are those obtained directly from a natural or synthetic source without further purification treatment.
- a shale oil obtained directly from retorting operations a petroleum oil obtained directly from distillation or ester oil obtained directly from an esterification process and used without further treatment would be unrefined oil.
- Refined oils are similar to the unrefined oils except they have been further treated in one or more purification steps to improve one or more properties. Many such purification techniques, such as distillation, solvent extraction, acid or base extraction, filtration and percolation are known to those skilled in the art.
- Re-refined oils are obtained by processes similar to those used to obtain refined oils applied to refined oils which have been already used in service. Such re-refined oils are also known as reclaimed or reprocessed oils and often are additionally processed by techniques for approval of spent additive and oil breakdown products.
- base oil examples include gas-to-liquid (“GTL”) base oils, i.e. the base oil may be an oil derived from Fischer-Tropsch synthesised hydrocarbons made from synthesis gas containing H 2 and CO using a Fischer-Tropsch catalyst. These hydrocarbons typically require further processing in order to be useful as a base oil. For example, they may, by methods known in the art, be hydroisomerized; hydrocracked and hydroisomerized; dewaxed; or hydroisomerized and dewaxed.
- GTL gas-to-liquid

- the combination of an oil-soluble benzotriazole metal deactivator, as an additive in a minor amount, and a ZDDP, as an additive in a minor amount, in a lubricating oil composition, comprising an oil of lubricating viscosity in a major amount, also suppresses both biodiesel induced lead and copper corrosion; the level of copper corrosion being reduced by approximately 70 % and the level of lead corrosion being reduced by approximately 30 % (Compare Reference Lubricant 7 with Reference Lubricant 6).
- a 5W-30 multigrade base crankcase lubricating oil composition (Oil C) was prepared by admixing an oil of lubricating viscosity (a mixture of Group IV and Group III base stocks (70 mass %)) and a viscosity modifier concentrate (9.5 mass %) with a commercial additive package containing an overbased detergent, a dispersant, an antioxidant and a ZDDP. Oil C has a phosphorus content of 0.06 mass % and a sulphated ash content of 0.6 mass %.
- Lubricants 9 and 10 of the invention are prepared by admixing Oil C with an oil-soluble carbodiimide compound (Additin RC8500 TM ).
- Petroleum gasoline fuel designated as E0
- E0 Petroleum gasoline fuel
- E0 was added to Oil C to form Reference Lubricant 8
- Lubricant 9 of the invention to simulate contamination of the oil during operation of a spark-ignited internal combustion engine fuelled with petroleum gasoline fuel.
- Bioethanol fuel (E85 comprising a mixture of E100 bioethanol (85 mass %) and petroleum gasoline (15 mass %)) was added to Oil C to form Reference Lubricant 9 and also to Lubricant 10 of the invention to simulate contamination of the oil during operation of a spark-ignited internal combustion engine fuelled with bioethanol fuel.
