ATO24 Engine Oil

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. In addition, our product portfolio offers power steering, hydraulic and brake fluids according to various specifications for purchase, in order to have the right fuel for every vehicle.

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.

API SN Plus Oil vs. LSPI

"Smaller" (downsized) engines with turbochargers and direct injection are widely used nowadays. After all, they make it possible to reduce CO2 emissions. At first glance, this sounds very good, but it has one drawback - the problem of Low Speed Pre-Ignition, or LSPI for short.

LSPI describes the combustion of the fuel-air mixture in the combustion chamber of an engine that takes place before the actual combustion initiated by ignition sparks. This can lead to excessive pressure in the cylinder and, in the worst case, cause serious damage to the engine.

Low Speed Pre-Ignition presents the automotive industry with a major dilemma - on the one hand, they want to meet the ever-growing demand for fuel-efficient vehicles, but on the other hand, the engines specially designed for this purpose are susceptible to LSPI.

What to do against LSPI?

Research on LSPI shows that, among other things, the formulation of the engine oil plays an important role in solving the LSPI problem. For this reason, calls from the automotive industry for engine oils that can counteract the problem of LSPI have been growing.

Now, the American Petroleum Institute (API) has responded to these demands with the API SN Plus specification.

What does API SN Plus mean?

Strictly speaking, the API SN Plus specification is not a completely new engine oil specification, but an addition to the existing API SN and ILSAC GF-5 specifications. API SN Plus has been valid since May 2018 and was developed specifically for "downsized" engines with exhaust gas turbochargers and direct injection systems, which require an engine oil with the API SN specification, in order to counteract the problem of Low Speed Pre-Ignition (LSPI) and to protect vehicles or the engines from LSPI.

As mentioned earlier, API SN + is the most current specification of the API classifications created by the American Petroleum Institute. The API classifications distinguish between gasoline and diesel classifications, which are identified either by the letter "S" for Service or Spark Ignition for gasoline engines and by the letter "C" for Commercial or Compression Ignition for diesel engines. This is followed by another letter that reflects the quality level - the higher the letter, the more demanding the test for the oil.

What is the difference between API SN and API SN Plus?

API SN + essentially corresponds to the API SN specification, but is supplemented by an additional test against LSPI (API Sequence IX Test). This can be seen very well in the following graphic: API SN is marked with the yellow line, while API SN Plus is marked with the red line. The values that must be achieved in the individual tests or sequences in order to obtain the API SN license are identical to the values that are required for the API SN Plus license. As a result, the two lines are mostly on top of each other, which makes the line orange. The only difference between the two specifications is the test against LSPI (API Seq. IX), which only applies to API SN Plus.

API SN Plus is backwards compatible with API SN, which means that engines that require an engine oil with the API SN specification can also use an engine oil with the API SN Plus specification.

API SN+ for which cars?

All cars that have a small (downsized) engine with turbocharger and direct injection technology have a higher LSPI risk. To a large extent, downsized engines are engines with three cylinders and a total displacement between 1.0 to 1.5 L.

If an engine of this type requires an engine oil with the specification API SN, then it is recommended to resort to an engine oil with the specification API SN +, due to the backward compatibility with API SN, in order to prevent potential low speed pre-ignition and protect the engine from LSPI. The vehicle owner's manual can be used to determine if an engine oil with the API SN specification is needed.

API SN Plus and GM dexos

API SN Plus, along with the GM dexos 1 Gen. 2 release, is the first step in the fight against LSPI. At the end of 2019 / beginning of 2020, the ILSAC GF-6 specification is expected to put even more focus on protection against LSPI.
