0W-40, 5W-40 | Engine Oils

Huge selection of motor oil from many manufacturers. You have the choice!

Among all lubricants and fuels in the car, engine oil is of particular importance. As the central link between mechanical friction and power generation, the engine oil plays a decisive role in the transmission of power from the engine in the car and is therefore exposed to various loads during each individual journey. If one considers that the intervals between oil changes are sometimes as short as 30,000 km, the importance of engine oil quality becomes even clearer.

Engine oils can essentially be distinguished by their viscosity, their manufacturer's approval or recommendation, and their basic chemical structure. Usually the viscosity is specified in an SAE class. In modern passenger cars, multi-grade engine oils are used which are capable of exhibiting different viscosities in the cold state, such as when the vehicle is cold-started, and in the warm state, i.e. at regular operating temperature up to the maximum load. This is a significant advantage, as an engine oil is thus able to ensure the rapid lubrication of an engine during a cold start with the highest possible flowability, thus guaranteeing qualitative aggregate protection, while at the same time offering a higher viscosity at high operating temperatures in order to be able to maintain a reliable lubricating film under heavy loads. Widely used viscosity grades in cars are SAE 0W-30, 5W-30 and 5W-40, which have replaced the once dominant viscosity 10W-40. An engine oil with a viscosity of 0W-30 is more fluid in comparison to the 5W-30 engine oil when cold and is therefore able to oil the engine more quickly and build up a protective lubricating film more quickly. In addition to the viscosity, automobile manufacturers limit the quality requirements for an engine oil to be used more precisely by specifications or so-called manufacturer's approvals. Common specifications are defined by the manufacturer-independent institutions ACEA (Association des Constructeurs Européens d'Automobiles), the API (American Petroleum Institute) or the ILSAC (International Lubricants Standardization and Approval Committee). Lubricant manufacturers can produce their products according to the classes defined in each case, such as ACEA A3/B4, API SN or ILSAC GF-5, while automotive manufacturers define which specifications must be met for the various vehicles. By specifying an engine oil specification, it is possible to identify in particular whether an engine oil is suitable only for petrol engines or also for vehicles with diesel engines. In the case of requirements for a lubricant individually defined by the vehicle manufacturer, a standardised specification is replaced by the so-called manufacturer approval or operating instructions. An approval is issued directly by the vehicle manufacturer. Oil manufacturers use it to produce products that meet the technical requirements of such an approval. Some of these products are then licensed and officially approved by the car manufacturer (in our online shop, the approvals of an engine oil  are listed in the product details under "approvals:") or recommended by the lubricant manufacturer as being suitable for use in vehicles that require an engine oil of the respective operating regulation (in our online shop, these are delimited from the manufacturer releases as "recommendations"). The most popular operating regulations defined by the automobile manufacturers include BMW Longlife-01, Mercedes-Benz MB 229.52, VW 505 00 and 507 00 or GM dexos2. However, there are also various other approvals from the vehicle manufacturers BMW, Mercedes, VW, Ford, Chrysler and many others.

Die Viskosität 0W-40 zählt zu den niedrigviskosen Motoröl Viskositäten. Für viele Fahrzeuge wir ein 0W-40 Motoröl vom Hersteller zur Verwendung vorgeschrieben oder empfohlen. Wir erklären Dir was die 0W-40 Viskosität eigentlich bedeutet und wie Du das richtige Motoröl 0W40 auswählst.

Was bedeutet 0W-40?

SAE 0W-40 ist eine Mehrbereichs Viskosität. Die beiden Viskositätsindizes 0W und 40 weisen zunächst auf die Möglichkeit zur Ganzjahresverwendung hin (für Winter- und Sommereinsatz). Die Kaltviskosität 0W gibt die Fließfähigkeit des Öls bei niedrigen Temperaturen an. Ein 0W Motoröl ist also als im kalten Zustand sehr fließfähig zu bewerten. Dies kommt besonders beim Kaltstart dem Motor zu Gute, da das Öl in der Lage ist, sich besonders schnell zu verteilen.

Die Warmviskosität 40 gibt die Fließfähigkeit des Öls bei hohen Temperaturen (Angabe bezieht sich auf Temperatur von 100°C) an.

Was ist der Unterschied zwischen 0W-30 und 0W-40?

Hieraus ergibt sich entsprechend auch der Unterschied zwischen den verschiedenen Viskositätsklassen. 0W-30 und 0W-40 Motoröle weisen vergleichbare Fließfähigkeiten im kalten Zustand auf. Ein 0W-30 Motoröl hat bei Betriebstemperatur eine niedrigere Viskosität als das 0W-40 Motoröl. Es ist also "dünner".

Motoröl 0W40: Das solltest Du beachten!

Dein Fahrzeughandbuch sollte stets die erste Anlaufstelle sein, um das richtige Motoröl für Dein Auto zu finden. Findest Du hier die Angabe, dass SAE 0W-40 zu verwenden ist, bist Du fast fertig. Denn nicht alle 0W40 Motoröle sind gleich!

Beim Kauf eines 0W-40 muss auf die vorgeschriebenen Spezifikation und Freigabe geachtet werden. Sie stehen stellvertretend für die korrekten Inhaltsstoffe und Standards, die Dein Fahrzeughersteller vorgibt.

0W40 Motoröl Spezifikationen

Nach der korrekten Viskosität solltest Du prüfen, ob für das korrekte Motoröl für Dein Auto auch eine Spezifikation vorgeschrieben ist. Einen Hinweis darauf findest Du ebenfalls im Handbuch Deines Fahrzeugs.

Spezifikationen werden beispielsweise von den Institutionen ACEA, API, ILSAC oder JASO ausgegeben. Im folgenden findest Du eine Auswahl an Spezifikationen, die häufig zusammen mit der Viskosität 0W20 vorgeschrieben werden:

• ACEA A3/B4 0W-40 Motoröl
• ACEA C5 0W-40 Motoröl
• API SN 0W-40 Motoröl

0W-40 Motoröl Freigaben

Neben den Spezifikationen spielen die Herstellerfreigaben bzw. Herstellerempfehlungen eine wichtige Rolle bei der Auswahl des Motoröls.

Hestellerfreigaben werden von den Fahrzeugherstellern ausgegben und aktualisiert, um sie an die Anforderungen der jeweiligen Motorengenerationen anzupassen. Auf den folgenden Seiten findest Du Öle, die die angegebenen Freigaben erhalten oder vom Hersteller des Öls zur entsprechenden Verwendung empfohlen werden:

• Volkswagen VW 505 00 0W-40 Motoröl

What does 5W-40 mean?

The designation 5W-40 indicates the viscosity of your engine oil in a so-called SAE class. Briefly explained, there are two components of the specification: The number before the W stands for the viscosity of the engine oil in winter (index W) or in cold condition. The other index number refers to the fluidity in warm or operating condition.

A 5W-40 and a 5W-30 engine oil therefore have the same flowability at cold start. At operating temperature, a 5W-40 oil is more viscous. In order to be able to evaluate these characteristics for their effect on the protection of the engine, always the individual case is to be lit up.

You have the choice:

• Mercedes-Benz 5W-40 engine oil
• Toyota 5W-40 engine oil
• Nissan 5W-40 engine oil
• Volvo 5W-40 engine oil

Mix 5W-30 and 5W-40?

In principle, you may mix a 5W-30 and a 5W-40 engine oil - for example, if your engine has too little oil available and you do not have any engine oil in the correct viscosity at hand. In any case, you should make sure that specifications and approvals are adhered to in addition to the viscosity.

In the long run, mixing 5W-30 and 5W-40 engine oil is suboptimal because, depending on the mixing ratio, the actual viscosity of your engine oil will approach the mixed oil.
