ACEA A3/B4, 0W-30 | 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.

In ATO24's online shop, you will find products from well-known lubricant manufacturers as well as a wide range of OEM products with which car manufacturers sell lubricants under their own brand. Due to our wide range of products we are able to provide the right motor oil for almost every vehicle - at a reasonable price and with short delivery time, no matter if European, American, Asian vehicle, passenger car, SUV, sports car or super sports car.

The viscosity 0W-30 is one of the most popular engine oil viscosities. For many vehicles a 0W-30 engine oil is prescribed or recommended by the manufacturer. We explain to you what the 0W-30 viscosity actually means and how you can choose the right 0W-30 engine oil.

What does 0W-30 mean?

SAE 0W-30 is a multi-grade viscosity. The two viscosity indices 0W and 30 initially indicate the possibility of year-round use (for winter and summer use). The cold viscosity 0W indicates the flowability of the oil at low temperatures. A 0W engine oil can therefore be considered to be very free-flowing when cold. This is particularly beneficial to the engine during cold starts, as the oil is able to spread particularly quickly.

The warm viscosity 30 indicates the flowability of the oil at high temperatures (specification refers to temperature of 100°C).

What is the difference between 0W-20 and 0W-30?

This also explains the difference between the various viscosity grades. 0W-20 and 0W-30 engine oils have comparable flow properties when cold. A 0W-30 engine oil has a higher viscosity at operating temperature than the 0W-20 engine oil. It is therefore "thicker".

Motoröl 0W30: You should pay attention to this!

Your vehicle manual should always be the first place to go to find the right engine oil for your car. If you find the information that SAE 0W-30 is to be used, you are almost done. Because not all 0W30 engine oils are the same!

When buying a 0W-30 you have to pay attention to the prescribed specification and approval. They are representative of the correct ingredients and standards set by your vehicle manufacturer.

0W-30 Engine Oil Specifications

After the correct viscosity, you should check whether a specification is also prescribed for the correct engine oil for your car. You will also find a reference to this in the manual of your vehicle.

Specifications are issued, for example, by the institutions ACEA, API, ILSAC or JASO. Below you will find a selection of specifications that are often prescribed together with the viscosity 0W30:

 

0W-30 Engine Oil Approval

In addition to the specifications, the manufacturer's approvals or manufacturer's recommendations play an important role in the selection of the engine oil.

Manufacturer's approvals are issued and updated by the vehicle manufacturers in order to adapt them to the requirements of the respective engine generations. On the following pages you will find oils that have received the specified approvals or are recommended by the manufacturer of the oil for the corresponding use:

 



What does ACEA A3/B4 mean?


ACEA A3/B4 engine oils are often 5W-30, 5W-40 or 10W-30 oils that are usually targeted at modern passenger car gasoline and diesel models from various manufacturers.

ACEA A3/B4 5W-30 and 5W-40 engine oils are usually based on API Group III base oils, while ACEA A3/B4 10W-40 engine oils often contain both Group I, Group II and Group III base oils.

For the ACEA A3/B4 specification, an HTHS viscosity greater than or equal to 3.5 cP is required.

Since 2004, the European ACEA (Association des Constructeurs Européens d'Automobiles) has continued to develop the ACEA A3/B3 specification and revise its requirements:

  • ACEA A3/B4-21
  • ACEA A3/B4-16
  • ACEA A3/B4-12
  • ACEA A3/B4-10
  • ACEA A3/B4-08
  • ACEA A3/B4-07
  • ACEA A3/B4-04


Which viscosity for ACEA A3/B4 engine oil?


Which viscosity you can use in connection with the ACEA A3/B4 viscosity, depends strongly on your vehicle and/or the installed engine. In the vehicle manual of your car you will find a detailed description of how you should select your engine oil.

In the online store of ATO24 you will find ACEA A3/B4 oils of various viscosities. Hereunder are among other things:
