All lubricants for your car  - buy at ATO24!

For reliable, safe and low-wear operation, the right lubricants and operating fluids are essential for a car, be it a passenger car or commercial vehicle. Lubricants and operating materials are mainly classified as liquids, such as oils and coolants, as well as more solid substances such as greases. The wear protection and performance development of a vehicle are subject to several different properties of these substances. An essential function of oil or grease is obvious: the lubrication of vehicle components such as engine, transmission, steering and chassis. This contributes to achieving the desired performance and protects the vehicle from wear and tear. Another, but equally important, function quickly fades into the background: cooling the components. Especially in the engine and transmission, the cooling function of the oil is existential, alongside the coolant in the vehicle's water circuit! Operating fluids such as brake fluid or hydraulic fluids play a key role in the safety of a vehicle. These are also exposed to high thermal and physical loads, which is why consistent performance is important. ATO24 is your competent partner from refilling the engine oil to the complete engine, coolant or transmission oil change. In the ATO24 online shop you can get high quality engine oils and transmission oils for automatic transmissions, manual transmissions, as well as differential and transfer cases in a large selection of over 30 brands at reasonable prices.

The viscosity 0W-20 is one of the low viscosity engine oil viscosities. For many vehicles a 0W-20 engine oil is prescribed or recommended by the manufacturer for use. We explain what the 0W-20 viscosity actually means and how you can choose the right 0W20 engine oil.

What does 0W-20 mean?

SAE 0W-20 is a multi-grade viscosity. The two viscosity indices 0W and 20 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 20 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-20 engine oil has a lower viscosity at operating temperature than the 0W-30 engine oil. It is therefore "thinner."

Engine oil 0W20: 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-20 is to be used, you are almost done. Because not all 0W20 engine oils are the same!

When buying a 0W-20 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-20 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. In the following you will find a selection of specifications that are often prescribed together with the viscosity 0W20:

• ACEA A1/B1 0W-20 Engine Oil
• ACEA C5 0W-20 Engine Oil
• API SN 0W-20 Engine Oil
• ILSAC GF-5 0W-20 Engine Oil

0W-20 Engine Oil Approvals

In addition to the specifications, the manufacturer's approvals or manufacturer's recommendations play an important role in the selection of 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 receive the specified approvals or are recommended by the manufacturer of the oil for the corresponding use:

• BMW Longlife-17 FE 0W-20 Engine Oil
• Chrysler MS-6395 0W-20 Engine Oil
• Mercedes-Benz MB 229.71 0W-20 Engine Oil
• Volkswagen VW 509 00 0W-20 Engine Oil

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.

Buy the right 5W-40 online at ATO24!

With a wide selection of 5W-40 oils, the online store of ATO24 certainly has a suitable 5W-40 engine oil for your car ready. Simply orient yourself to the required specifications or approvals / recommendations, which the manufacturer of your vehicle prescribes. You can find this manufacturer information in your vehicle manual.

Often a 5W-40 engine oil is required in combination with the following releases / recommendations or specifications:

• Buy 5W-40 API SN engine oil
• Buy 5W-40 ACEA A3/B4 engine oil
• Buy 5W-40 BMW Longlife-04 engine oil
• Buy 5W-40 Mercedes-Benz MB 229.51 engine oil
• Buy 5W-40 VW 505 00 Engine Oil for Volkswagen / Audi / Skoda / Seat

5W-40 oil from OEM: Mercedes-Benz, Toyota, Nissan, Volvo and more.

In addition to products from internationally known oil brands, you can also find OEM products from vehicle manufacturers at ATO24. Often, these are also explicitly tailored to the characteristics of the engines of this one manufacturer and / or it is the products with which your vehicle is filled from the factory (so-called first fill). 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.
