Definitions
- the present invention relates to environmentally friendly lubricating oil compositions for automotive engines.
- Lubricating oil compositions for use in automotive engines are well known.
- EP-A-0 259 809 discloses, a lubricating oil composition comprising 97 to 60% by weight of mineral oil and 3 to 40% by weight of polyester, said mineral oil having a dynamic viscosity at 100°C of 2 to 50 centistokes, a pour point ( as determined by JIS K-2269) of -5 to -30°C, a viscosity index (as determined by JIS K-2283) of not less than 80 and % C A of not more than 3.
- This lubricating oil composition is suitable for lubrication of parts including a wet brake and a wet clutch, such as automatic transmissions and tractors.
- compositions usually contain a base fluid which may comprise mineral oils, hydrocarbon oils and/or synthetic fluids and conventional additives such as viscosity index (hereafter "VI”) improvers, anti-oxidants, corrosion inhibitors, dispersants, anti-wear additives and sludge control agents.
- VI viscosity index
- automotive engine oil development has seen a steady trend towards lower viscosity multigrades, principally to improve fuel efficiency.
- the predominant viscosity grade has moved from a typically 20W/50 oil to a 10W/40 or a 5W/40 oil.
- the manufacturers of automotive engine equipment have also tightened the specifications for such oils in terms of oil consumption, bearing protection and shear stability.
- compositions usually contain 80%w.w or more of a hydrocarbon or mineral oil and upto 20%w/w of an aliphatic carboxylic acid ester in the base fluid.
- Such compositions whilst being very efficient and being to some extent biodegradable, still leave room for improvement.
- base oil blends can be formulated which not only improve the biodegradability thereof but achieve the same without loss of performance at the same time exhibiting relatively lower emissions, lower fuel consumption and lower oil consumption.
- the present invention is an automotive engine lubricating oil composition which has a major proportion of a base fluid which fluid comprises a blend of:
- the base fluid comprises a blend of an ester and a hydrocarbon oil.
- the ester component (a) is derivable by the reaction of an aliphatic mono-, di-and/or poly-carboxylic acid with, isotridecyl alcohol under esterification conditions.
- esters include the isotridecyl esters of octane-1,8-dioic acid, 2-ethylhexane-1,6-dioic acid and dodecane-1,12-dioic acid.
- the hydrocarbon oil component (b) in the blend suitably is a hydrocracked wax distillate. More specifically, such hydrocarbon oils can contain upto 99.5%w/w, preferably upto 97%w/w, of aliphatic hydrocarbons and no more than 10%w/w of aromatic hydrocarbons.
- aliphatic hydrocarbons as used herein and throughout the specification is meant to include open chain aliphatic hydrocarbons as well as cycloaliphatic hydrocarbons such as e.g. naphthenic hydrocarbons.
- the total polycyclic aromatic hydrocarbons in the hydrocarbon oil is suitably less than 10 ppm, preferably less than 5 ppm and more preferably less than 1 ppm. Typically such hydrocarbon oil contains from 92-97% w/w of aliphatics and 3-8% w/w of aromatics.
- the hydrocarbon oil component (b) in the blend is suitably prepared by feeding a waxy distillate through a hydrocracker at 70-95% conversion under elevated temperature and hydrogen pressure.
- a hydrocracker In the first stage of this hydrocracker, sulphur and nitrogen compounds are removed and in the second stage the aromatics are hydrogenated to naphthenes; the hydrogenated products including the naphthenes are cleaved and rearranged to produce a controlled range of paraffins and isoparaffins.
- Fuels and lubricant products are separated by atmospheric distillation from the resultant hydrocracked products and the 5-35% heavy component is the hydrocarbon fraction used as the hydrocarbon oil component (b) in the blend.
- a product produced by this method is substantially free of any unsaturates.
- This feedstock can be further refined, if necessary, by conventional techniques such as additional fractionation, extraction or dewaxing to obtain the finished product.
- the resultant hydrocarbon oil has the following physical characteristics:
- about 20% w/w comprises isoparaffins having an average carbon number of about 27.
- the relative amounts of the ester component (a) and the hydrocarbon oil component (b) in the base fluid within the specified ranges above will depend upon the nature of the two components and their relative viscosities. For instance, if the hydrocarbon component (b) is within the physical characteristic specification defined above, and the ester component (a) is isotridecyldodecanedioate, the amount of ester (a) in the blend may suitably vary from 30-50% w/w, preferably from 40-50% w/w.
- the lubricating composition of the present invention comprises minor proportions of conventional additives which include inter alia the following: one or more sludge dispersants, one or more VI improvers, one or more anti-wear additives, and one or more anti-oxidants.
- the additive package used is known to comprise components which meet the stringent requirements of an API Performance Classification "SG". These requirements include successful testing in the following categories: rust test, dispersancy test, piston varnish test, low temperature sludge test and wear test.
- Such additives are commercially available as an additives package sold e.g. as an "SG Additive Package" under the names GBX 2900 and GBX 2905 (both ex Adibis Ltd, UK).
- Such an additive package suitably forms from 10-20% w/w, preferably from 11-16% w/w of the formulated lubricating composition.
