Definitions
- the invention relates to the use of a lubricant composition for internal combustion engines containing an oil with lubricating viscosity (base oil) in an amount of 97 to 50% by weight and 3 to 25% by weight of diisooctyl sebacate to reduce fuel consumption in the cold running phase of the internal combustion engine.
- base oil oil with lubricating viscosity
- Lubricating oils for internal combustion engines are continuously modified in order to meet the constantly increasing requirements resulting from the further development of engine technology.
- Different organizations such as the Society of Automotive Engineers (SAE), the American Petroleum Institute (API) and the motor vehicle manufacturers set the quality standards.
- SAE Society of Automotive Engineers
- API American Petroleum Institute
- lubricants should maintain their lubricating properties for as long as possible, that is, they should be less rapidly degraded during operation even under extreme loads.
- the aim is to reduce abrasion and the formation of deposits such as sludge, carbon and resins that could deposit on various parts of the engine.
- the oils should produce a good lubricating effect and at the same time a low resistance over the entire operating temperature range of the engine.
- CN 103 232 884 A discloses an energy saving oil containing diisooctyl sebacate with improved cold start properties for diesel engines.
- the engine oils known to date do not always meet these requirements in a satisfactory manner.
- the object of the present invention was therefore to provide an improved lubricant composition which, when used in internal combustion engines, leads to reduced fuel consumption.
- the fuel consumption and thus the CO 2 emissions should be reduced during the cold running phase of the internal combustion engine.
- the object is achieved by a lubricant composition for internal combustion engines containing 97 to 50% by weight of a base oil and 3 to 25% by weight of diisooctyl sebacate.
- diisooctyl sebacate in certain concentrations in a base oil, fuel savings could not only be achieved compared to a reference oil with no additives in this regard, but also an increase in fuel savings with regard to oils of the same viscosity classes that were provided with other additives to save fuel .
- diisooctyl sebacate is understood to mean the substance di-2-ethylhexyl sebacate.
- Another advantage of the lubricant composition used according to the invention is that the use of diisooctyl sebacate opens up the possibility of producing oils with a classification value of SAE class 0W-X (with X, for example, 20, 30, 40, 50 or 60), without the need to use a fully synthetic oil as the base oil.
- a base oil is understood to mean an oil with a lubricating viscosity. Natural oils, synthetic oils, semi-synthetic oils or their mixtures can be used for this.
- natural oils are animal oils and vegetable oils, e.g. B. castor oil and mineral lubricating oils, e.g. B. liquid petroleum oils and solvent-treated or acid-treated mineral lubricating oils paraffinic, naphthenic or mixed paraffinic-naphthenic type. Oils made from coal or oil shale with a lubricating viscosity can also be used as base oils.
- synthetic lubricating oils are hydrocarbon oils and oils based on halogen-substituted hydrocarbons, e.g. B. homopolymerized and copolymerized olefins, e.g.
- polybutylenes polypropylenes, propylene-isobutylene copolymers, chlorinated polybutylenes, poly (1-hexene), poly (1-octene) and poly (1-decene) and their mixtures, alkylbenzenes, such as dodecylbenzenes, tetradecylbenzenes, dinonylbenzenes and di- (2-ethylhexyl) -benzenes, polyphenyls such as biphenyls, terphenyls or alkylated polyphenyls, alkylated diphenyl ethers and alkylated diphenyl sulfides and their derivatives, analogs and homologs.
- alkylbenzenes such as dodecylbenzenes, tetradecylbenzenes, dinonylbenzenes and di- (2-ethylhexyl) -benzenes
- Alkylene oxide polymers and copolymers and their derivatives in which the terminal hydroxyl groups, e.g. B. have been modified by esterification or etherification, are also suitable as synthetic lubricating oils.
- oils are the polymerization products of ethylene oxide or propylene oxide, and the alkyl and aryl ethers of these polyoxyalkylene polymers.
- esters of dicarboxylic acid e.g. B. phthalic acid, succinic acid, alkylsuccinic acids and alkenylsuccinic acids, maleic acid, azelaic acid, suberic acid, sebacic acid, fumaric acid, adipic acid, linoleic acid dimer, malonic acid, alkylmalonic acids or alkenylmalonic acids, with various alcohols, such as butanol, hexyl alcohol, dodecyl alcohol, ethyl alcohol, 2-ethylene or propylene glycol.
- dicarboxylic acid e.g. B. phthalic acid, succinic acid, alkylsuccinic acids and alkenylsuccinic acids, maleic acid, azelaic acid, suberic acid, sebacic acid, fumaric acid, adipic acid, linoleic acid dimer, malonic acid, alkylmalonic acids or alkenylmalonic acids, with
- esters are dibutyl adipate, di- (2-ethylhexyl) sebacate, di-n-hexyl fumarate, diisooctyl azelate, diisodecyl azelate, dioctyl phthalate, didecyl phthalate, dieicosyl sebacate, the 2-ethylhexyl diester of linoleic acid dimer, and the Sebacic acid ester prepared with 2 moles of tetraethylene glycol and 2 moles of 2-ethylcaproic acid.
- esters suitable as synthetic oils derive e.g. of C5-C12 monocarboxylic acids and polyols or polyol ethers, such as neopentyl glycol, trimethylolpropane, pentaerythritol, dipentaerythritol or tripentaerythritol.
- Silicone oils such as polyalkyl, polyaryl, polyalkoxy or polyaryloxysilosane oils and silicate oils are also suitable as synthetic lubricants. Examples are tetraethylsilicate, tetraisopropylsilicate, tetra- (2-ethylhexyl) -silicate, tetra- (4-methylhexyl) -silicate, tetra- (p-tert-butylphenyl) -silicate, hexyl- (4-methyl-2-pentoxy) -disiloxane, poly- (methyl) -siloxane and poly- (methylphenyl) -siloxane.
- Suitable synthetic lubricating oils are e.g. liquid esters of phosphorus-containing acids such as tricresyl phosphate, trioctyl phosphate and the diethyl ester of decylphosphonic acid, as well as polymeric tetrahydrofurans.
- Unrefined, refined and second-refined, natural or synthetic oils and mixtures of two or more of these oils can be used in the lubricant compositions used according to the invention.
- Unrefined oils are obtained directly from natural or synthetic sources without further purification.
- shale oil is obtained directly from the retort process, petroleum oil directly from distillation and ester oils directly from esterification. Without further treatment, they are an unrefined oil.
- the refined oils are derived from the unrefined oils, but are treated in one or more purification stages in order to improve one or more properties. Numerous methods are known for cleaning, e.g. solvent extraction, hydrogen refining, secondary distillation, extraction with acids or bases, filtration or percolation.
- Secondly refined oils are obtained, similar to refined oils, by reprocessing used oils. These second-refined oils are also known as regenerated oils, which are often additionally treated to separate used additives and oil breakdown products.
- the fuel saving values determined in the context of the present invention relate exclusively to the so-called new European driving cycle (NEDC), as it has been used in the European Union since January 01, 1996 to determine the fuel consumption of motor vehicles.
- NEDC new European driving cycle
- the driving resistances that is to say the rolling and air resistance on the road
- the measured driving resistances are then transferred to a roller dynamometer.
- the standardized driving cycle is then run on the roller dynamometer and the exhaust emissions are measured.
- the fuel consumption can then be calculated from the measured exhaust emissions.
- the NEDC has a test duration of 1180 seconds in total, i.e. around 20 minutes. It is divided into a city cycle starting at the beginning of the test with a duration of 780 seconds and a subsequent overland cycle lasting 400 seconds. A graph of the speed / time profile is shown in Fig. 1 pictured. The ambient temperature is 20 to 30 ° C during the measurement, whereby cold start conditions, accelerations and decelerations are recorded and interpolated accordingly.
- a common rail diesel engine with 1995 cm 3 displacement with a VTG turbocharger and intercooler from the manufacturer BMW was used (engine code N47), the vehicle model BMW 320 d, series E 91 being taken as the basis.
- the lubricant composition contains 4 to 25% by weight of diisooctyl sebacate, in particular 5 to 15% by weight, preferably 5 to 12% by weight, more preferably 5 to 10% by weight or even 5 to 9% by weight .-%. This is particularly advantageous because, when using diisooctyl sebacate, a noticeable reduction in fuel consumption can be achieved even in smaller quantities.
- the lubricant composition can further contain an additive.
- an additive can be selected, for example, from antioxidants, metal passivators, corrosion inhibitors, viscosity index improvers, deposit inhibitors, detergents, dispersants, anti-wear additives and friction modifiers.
- antioxidants for example phenolic or aminic antioxidants, diphenylamines, aliphatic and aromatic phosphites, esters of thio-di-propionic acid, butyl-hydroxyanisole, butyl-hydroxyltoluene, methoxyhydroquinone, 2,2,4-tri-methyl-1,2-di- Hydroquinoline, 3- (3,5-di-tert-butyl-4-hydroxyphenyl) propionic acid octadecyl ester, tocopherol or mixtures of these can be used.
- the proportion of antioxidants can be, for example, 0.5 to 6% by weight, in particular 1.0 to 3.0% by weight.
- alkylated phenyl-alpha-naphthylamines available under the name Irganox® L06 from BASF SE
- methylene-bis-dialkyldithiocarbamates such as methylene-bis- (dibutyldithiocarmate), available under the name Vanlube® 7723 from Vanderbilt Chemicals, is preferred, LLC.
- the use of a combination of alkylated phenyl-alpha-naphthylamines and dialkyldithiocarbamates is particularly preferred, since this achieves a particularly good antioxidant effect.

Description
Die Erfindung betriff die Verwendung einer Schmiermittelzusammensetzung für Verbrennungsmotoren enthaltend ein Öl mit Schmierviskosität (Grundöl) in einer Menge von 97 bis 50 Gew.-% sowie 3 bis 25 Gew.-% Diisooctylsebacat zur Verringerung des Kraftstoffverbrauchs in der Kaltlaufphase des Verbrennungsmotors.The invention relates to the use of a lubricant composition for internal combustion engines containing an oil with lubricating viscosity (base oil) in an amount of 97 to 50% by weight and 3 to 25% by weight of diisooctyl sebacate to reduce fuel consumption in the cold running phase of the internal combustion engine.
Schmieröle für Verbrennungsmotoren, insbesondere Automotoren und Dieselmotoren, werden fortlaufend modifiziert, um den ständig steigenden Anforderungen zu genügen, die aus der Weiterentwicklung der Motorentechnik resultieren. Unterschiedliche Organisationen, wie die Society of Automotive Engineers (SAE), das American Petroleum Institute (API) sowie die Kraftfahrzeughersteller legen die Qualitätsstandards fest. Schmiermittel sollen einerseits möglichst lange ihre Schmiereigenschaften aufrechterhalten, das heißt im Betrieb auch unter extremen Belastungen weniger rasch abgebaut werden. Dabei sollen Abrieb und die Bildung von Abscheidungen, wie Schlamm, Kohlenstoff und Harze, die sich an verschiedenen Teilen des Motors niederschlagen könnten, vermindert werden. Zudem sollen die Öle über das gesamte Betriebstemperaturspektrum des Motors eine gute Schmierwirkung und gleichzeitig einen geringen Wiederstand erzeugen.Lubricating oils for internal combustion engines, especially car engines and diesel engines, are continuously modified in order to meet the constantly increasing requirements resulting from the further development of engine technology. Different organizations such as the Society of Automotive Engineers (SAE), the American Petroleum Institute (API) and the motor vehicle manufacturers set the quality standards. On the one hand, lubricants should maintain their lubricating properties for as long as possible, that is, they should be less rapidly degraded during operation even under extreme loads. The aim is to reduce abrasion and the formation of deposits such as sludge, carbon and resins that could deposit on various parts of the engine. In addition, the oils should produce a good lubricating effect and at the same time a low resistance over the entire operating temperature range of the engine.
Die bislang bekannten Motorenöle erfüllen diese Anforderungen nicht immer in zufriedenstellender Weise. Die Aufgabe der vorliegenden Erfindung bestand somit darin, eine verbesserte Schmiermittelzusammensetzung zur Verfügung zu stellen, die bei der Verwendung in Verbrennungsmotoren zu einem verringerten Kraftstoffverbrauch führt. Dabei soll insbesondere der Kraftstoffverbrauch und damit der CO2-Ausstoß während der Kaltlaufphase des Verbrennungsmotors reduziert werden.The engine oils known to date do not always meet these requirements in a satisfactory manner. The object of the present invention was therefore to provide an improved lubricant composition which, when used in internal combustion engines, leads to reduced fuel consumption. In particular, the fuel consumption and thus the CO 2 emissions should be reduced during the cold running phase of the internal combustion engine.
Die Aufgabe wird gelöst durch eine Schmiermittelzusammensetzung für Verbrennungsmotoren enthaltend 97 bis 50 Gew.-% eines Grundöls, sowie 3 bis 25 Gew.-% Diisooctylsebacat.The object is achieved by a lubricant composition for internal combustion engines containing 97 to 50% by weight of a base oil and 3 to 25% by weight of diisooctyl sebacate.
Überraschenderweise wurde gefunden, dass durch den Einsatz von Diisooctylsebacat in bestimmten Konzentrationen in einem Grundöl eine Kraftstoffeinsparung nicht nur gegenüber einem in dieser Hinsicht unadditivierten Referenzöl erzielt werden konnte, sondern auch eine Steigerung der Kraftstoffeinsparung hinsichtlich Ölen gleicher Viskositätsklassen, die mit anderen Additiven zur Kraftstoffeinsparung versehen sind. Im Rahmen der vorliegenden Erfindung wird unter Diisooctylsebacat die Substanz Di-2-ethylhexylsebacat verstanden.Surprisingly, it was found that by using diisooctyl sebacate in certain concentrations in a base oil, fuel savings could not only be achieved compared to a reference oil with no additives in this regard, but also an increase in fuel savings with regard to oils of the same viscosity classes that were provided with other additives to save fuel . In the context of the present invention, diisooctyl sebacate is understood to mean the substance di-2-ethylhexyl sebacate.
Ein weiterer Vorteil der erfindungsgemäß verwendeten Schmiermittelzusammensetzung besteht darin, dass durch den Einsatz von Diisooctylsebacat die Möglichkeit eröffnet wird, Öle mit einem Klassifikationswert der SAE-Klasse 0W-X (mit X beispielsweise gleich 20, 30, 40, 50 oder 60) zu erzeugen, ohne dass hierfür die Verwendung eines Vollsynthetiköls als Grundöl erforderlich ist.Another advantage of the lubricant composition used according to the invention is that the use of diisooctyl sebacate opens up the possibility of producing oils with a classification value of SAE class 0W-X (with X, for example, 20, 30, 40, 50 or 60), without the need to use a fully synthetic oil as the base oil.

Unrefined oils are obtained directly from natural or synthetic sources without further purification.
Beispielsweise erhält man Schieferöl direkt nach dem Retortenverfahren, Petroleumöl direkt bei der Destillation und Esteröle direkt bei der Veresterung. Ohne weitere Behandlung sind sie ein nicht-raffiniertes Öl. Die raffinierten Öle leiten sich von den nicht-raffinierten Ölen ab, werden jedoch in einer oder mehreren Reinigungsstufen behandelt, um eine oder mehrere Eigenschaften zu verbessern. Für die Reinigung sind zahlreiche Methoden bekannt, z.B. die Lösungsmittelextraktion, die hydrierende Raffination, Zweitdestillation, Extraktion mit Säuren oder Basen, Filtration oder das Perkolieren. Zweitraffinierte Öle werden ähnlich den raffinierten Ölen erhalten, indem man Altöle aufarbeitet. Diese zweitraffinierten Öle sind auch als regenerierte Öle bekannt, die oft noch zusätzlich behandelt werden, um verbrauchte Additive und Öl-Abbauprodukte abzutrennen.For example, shale oil is obtained directly from the retort process, petroleum oil directly from distillation and ester oils directly from esterification. Without further treatment, they are an unrefined oil. The refined oils are derived from the unrefined oils, but are treated in one or more purification stages in order to improve one or more properties. Numerous methods are known for cleaning, e.g. solvent extraction, hydrogen refining, secondary distillation, extraction with acids or bases, filtration or percolation. Secondly refined oils are obtained, similar to refined oils, by reprocessing used oils. These second-refined oils are also known as regenerated oils, which are often additionally treated to separate used additives and oil breakdown products.

Dazu werden in an sich bekannter Weise für die Ermittlung des Verbrauchs eines Fahrzeugs zunächst die Fahrwiederstände, das heißt der Roll- und Luftwiederstand auf der Straße exakt ermittelt und die gemessenen Fahrwiederstände danach auf einen Rollenprüfstand übertragen. Anschließend wird auf dem Rollenprüfstand der genormte Fahrzyklus abgefahren und dabei die Abgasemissionen gemessen. Aus den gemessen Abgasemissionen lässt sich anschließend der Kraftstoffverbrauch berechnen.The fuel saving values determined in the context of the present invention relate exclusively to the so-called new European driving cycle (NEDC), as it has been used in the European Union since January 01, 1996 to determine the fuel consumption of motor vehicles. For this purpose, the driving resistances, that is to say the rolling and air resistance on the road, are first exactly determined in a manner known per se to determine the consumption of a vehicle, and the measured driving resistances are then transferred to a roller dynamometer. The standardized driving cycle is then run on the roller dynamometer and the exhaust emissions are measured. The fuel consumption can then be calculated from the measured exhaust emissions.

Er teilt sich auf in einen am Testbeginn startenden City-Zyklus mit einer Dauer von 780 Sekunden und einem sich daran anschließenden 400 Sekunden dauernden Überland-Zyklus.

Gegenstand der vorliegenden Erfindung ist die Verwendung einer Schmiermittelzusammensetzung zur Verbesserung des Wirkungsgrades eines Verbrennungsmotor, wobei die Verbesserung des Wirkungsgrades des Verbrennungsmotors in einer Verringerung des Kraftstoffverbrauchs in der Kaltlaufphase des Motors erzielt werden.The present invention relates to the use of a lubricant composition for improving the efficiency of an internal combustion engine, the improvement in the efficiency of the internal combustion engine being achieved in a reduction in fuel consumption in the cold running phase of the engine.
Die vorliegende Erfindung wird im Folgenden anhand von Ausführungsbeispielen näher erläutert.The present invention is explained in more detail below on the basis of exemplary embodiments.
Die angegebenen Kennwerte hinsichtlich der SAE-Klasse der für die Beispiele verwendeten Motorenöle, bezieht sich auf die Klassifizierung nach SAE J 300.The specified characteristic values with regard to the SAE class of the engine oils used for the examples refer to the classification according to SAE J 300.
Die kinematische Viskosität bei 100 °C wurde gemäß ASTM D 445 bestimmt.The kinematic viscosity at 100 ° C. was determined according to ASTM D 445.
Die HTHS-Viskosität (High-Temperature-High-Share-Viskosität) wurde bestimmt nach ASTM D 4741.The HTHS viscosity (high temperature high share viscosity) was determined according to ASTM D 4741.
Die Werte für die dynamische Viskosität bei -35 °C, CCS (Cold Cranking Simulator) wurde bestimmt nach ASTM D 5293.The values for the dynamic viscosity at -35 ° C., CCS (Cold Cranking Simulator) were determined according to ASTM D 5293.
Die angegebenen Werte für die prozentuale Kraftstoffeinsparung wurden nach dem Neuen Europäischen Fahrzyklus (NEFZ) als Belastungsprofil ermittelt, wie er seit dem 01. Januar 1996 für die Ermittlung des Kraftstoffverbrauchs von Kraftfahrzeugen in der Europäischen Union eingesetzt wird. Im Rahmen der vorliegenden Erfindung wurde ein Common-Rail-Dieselmotor mit 1995 cm3 Hubraum mit einem VTG-Turbolader und Ladeluftkühler des Herstellers BMW verwendet (Motorcode N47), wobei als Fahrzeug das Fahrzeugmodell BMW 320 d, Baureihe E 91 hinsichtlich des Roll- und Luftwiederstand zugrunde gelegt wurde. Aus den über den Testzyklus gemessen Abgasemissionen wird anschließend der Kraftstoffverbrauch berechnet.The specified values for the percentage of fuel savings were determined according to the New European Driving Cycle (NEDC) as a load profile, as it has been used since January 1st, 1996 to determine the fuel consumption of motor vehicles in the European Union. In the context of the present invention, a common rail diesel engine with 1995 cm 3 displacement with a VTG turbocharger and intercooler from the manufacturer BMW was used (engine code N47), the vehicle model BMW 320 d, series E 91 with regard to the roll and Air resistance was used. The fuel consumption is then calculated from the exhaust emissions measured over the test cycle.
Der NEFZ hat eine Prüfdauer von insgesamt 1180 Sekunden, also in etwa 20 Minuten. Er teilt sich auf in einen am Testbeginn startenden City-Zyklus mit einer Dauer von 780 Sekunden und einem sich daran anschließenden 400 Sekunden dauernden Überland-Zyklus. Eine graphische Darstellung des Geschwindigkeits-/ Zeitprofils ist in
Als Referenz wurde ein Referenzöl 0W-30 verwendet, welches eine HTHS-Viskosität bei 150 °C von 3,5 mPa s aufweist.A reference oil 0W-30 was used as a reference, which has an HTHS viscosity at 150 ° C. of 3.5 mPa s.
Die erfindungsgemäßen Öle enthalten jeweils ein Grundöl. Diese Öle haben folgende Eigenschaften:
Die Grundöle der Gruppen 3 und 4 entsprechen den Definitionen des American Petroleum Institut (API).The base oils of groups 3 and 4 correspond to the definitions of the American Petroleum Institute (API).
TMP-caprylcaprat bzw. TMP-C8C10 bezeichnen Trimethylolpropan-caprylcaprat.TMP-caprylcaprate and TMP-C8C10 denote trimethylolpropane-caprylcaprate.
DiC13-Adipat steht für Diisotridecyladipat.DiC13 adipate stands for diisotridecyl adipate.
Es wurden insgesamt acht Motorenöle hergestellt. Diese haben die in der Tabelle B zusammengefassten Eigenschaften:
Die Zusammensetzung der Öle ist aus der folgenden Tabelle C ersichtlich. Bei dem Viskositätsverbesserer A, dem Pourpointverbesserer A und dem Additiv Package A handelt es sich um handelsübliche Additive beziehungsweise Additivmischungen.
Beispiel 4 ist nicht erfindungsgemäß.Example 4 is not according to the invention.
In der folgenden Tabelle D sind die Ergebnisse verschiedener Viskositätsuntersuchungen sowie die prozentuale Kraftstoffeinsparung gegenüber dem Referenzöl 0W-30 angegeben
Die Gegenüberstellung der erfindungsgemäßen Beispiele Bsp. 1 bis Bsp. 3 sowie Vgl. 1 bis Vgl. 4 zeigt zunächst, dass die mit Diisooctylsebacat formulierten Schmiermittelzusammensetzungen bei Einsatz desselben Grundöls im Wesentlichen gleiche Viskositätseigenschaften bei erhöhten Temperaturen zeigen. Demgegenüber zeigen die erfindungsgemäßen Schmiermittelzusammensetzungen bei Verwendung desselben Grundöls eine deutliche Reduzierung der dynamischen Viskosität bei -35 °C. Dies wirkt sich insbesondere vorteilhaft auf die Schmiereigenschaften während der Kaltlaufphase des Motors aus, insbesondere bei niedrigen Außentemperaturen im Winter.The comparison of examples according to the invention, Ex. 1 to Ex. 3, and Comp. 1 to Comp. 4, first shows that the lubricant compositions formulated with diisooctyl sebacate show essentially the same viscosity properties at elevated temperatures when using the same base oil. In contrast, the lubricant compositions according to the invention show a significant reduction in dynamic viscosity at -35 ° C. when using the same base oil. This has a particularly advantageous effect on the lubricating properties during the cold running phase of the engine, in particular when outside temperatures are low in winter.
Gleichzeitig zeigen sämtliche erfindungsgemäßen Beispiele eine deutlich verbesserte Kraftstoffeinsparung gegenüber den in dieser Hinsicht bereits additivierten Vergleichsbeispielen Vgl. 1 bis Vgl. 4. Hierbei ist zudem beachtlich, dass beim Vergleich der erfindungsgemäßen Beispiele Bsp. 1, Bsp. 2 und Bsp. 3, die auf demselben Grundöl Gruppe 3 basieren, innerhalb der NEFZ-Testgenauigkeit kein merklicher Unterschied bei der Kraftstoffeinsparung festgestellt werden kann. Mit anderen Worten führt bereits eine vergleichsweise geringe Additivierung von 7 Gew.-% Diisooctylsebacat zu einer spürbaren Kraftstoffeinsparung von mehr als 2,5 % verglichen mit dem Referenzöl.At the same time, all examples according to the invention show a significantly improved fuel saving compared to the comparative examples cf. 1 to cf. 4, which have already been added in this respect. It is also noteworthy that when comparing the examples according to the invention, example 1, example 2 and example 3, the same base oil Group 3, no noticeable difference in fuel savings can be determined within the NEDC test accuracy. In other words, even a comparatively small amount of additives of 7% by weight of diisooctyl sebacate leads to a noticeable fuel saving of more than 2.5% compared to the reference oil.
