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.

What does SAE 0W-16 mean?
The SAE viscosity classes are regarded as a standardized measure for classifying engine oils and are defined by the Society of Automotive Engineers (SAE) in Standard J300. When it comes to the question of which characteristic the oils can be classified according to, its flow behavior is found as an elementary criterion. This is differentiated for high and low temperatures (summer vs. winter).
For the following in-depth discussion, a distinction must generally be made between monograde oils and multigrade oils. In the case of single-grade oils, a distinction is made between oils for low temperatures and those for high temperatures. In the case of low temperatures, the viscosities (SAE 0W, SAE 5W, SAE 10W, etc.) are meant, which refer to the low-temperature pump viscosity. This refers to the lowest temperature at which the oil is still pumpable under specified conditions (SAE J 300). For SAE 0W, this would be -40 degrees. For the high temperatures, classes such as SAE 20, SAE 30 and others apply. Its flow behavior is recorded in kinematic viscosity (flow velocity in mm² per second) at 100 degrees.
Multigrade oils (e.g. 10W-40) exhibit both properties simultaneously and can thus be used in both temperature extremes. This property makes them known today as commonly applied oils.
Also relevant is the specification of HTHS viscosity (High-Temperature-High-Shear), which is considered a measure of flow behavior at high oil temperatures and engine speeds.
Until April 2013, SAE 0W-20 oils were considered the class with the lowest viscosity. But as of that date, a change was made in the international viscosity classification of engine oils according to SAE J300. The viscosity 0W-16 was officially included.
The following table shows the viscosities valid until April 2013 with their respective temperature-specific properties.
Due to the new 0W-16 class, this graphical representation can of course be updated. For this reason, a specially prepared table for the new low viscosity follows:
Before viscosity 16 came onto the market, fixed interval values (min. to max.) of kinematic viscosity served as the sole criterion for assigning engine oils to fixed viscosity classes. With SAE 16, this is no longer possible. As can be seen from the table, the maximum values of SAE 16 reach into the ranges of SAE 20. In order to enable an unambiguous class assignment, the HTHS viscosity is now required at the same time. The lower values of the kinematic viscosity indicate a thin fluid. The 0W-16 is therefore the thinnest engine oil on the market. The HTHS viscosity also shows decreasing values. Lower values stand for improved fuel economy, wear protection and reduced CO2 emissions. This is due to the fact that at a lower HTHS viscosity, frictional losses at higher engine temperatures are avoided and less fuel is converted into heat. Consequently, fuel is saved or engine performance is increased. Thus, viscosity grade 16 clearly excels in this respect.
0W-16 the new benchmark when it comes to efficiency?
Global consumerism has long since moved away from gas-guzzling engines with immoral pollutant emissions, and is increasingly focused on responsibility towards the ecological environment. Fuel efficiency and clean engines are shaping the current demand for automobiles. Engineers saw an opportunity to meet fuel efficiency especially in changing the viscosities of engine oils.
For the East-Westphalian lubricant manufacturer Ravenol, this marked the beginning of the battle to increase fuel efficiency in product development.
This work represents a step in the right direction, as the OEM sees it as a key goal in the future to reduce overall fuel consumption.
The crux of the matter is that the 0W-16 is only compatible for new engines and cannot be used for older vehicles, as this would lead to the opposite effect, i.e. wear.
Does a 0W-16 engine oil fit in your car?
Engines to which the 0W-16 is tailored are currently found in Japanese car manufacturers. They have already developed oils that are very similar to the 0W-16. Their application tests were convincing and have now led to a direct recommendation from the factory for the first cars. On the lower picture you see an excerpt from the service manual of a Toyota Ractis, in which the 0W-16 oil is already filled from factory and accordingly for later services directly recommended. In addition, the car manufacturer points out the greatest fuel efficiency when using a 0W-16 engine oil.
These recommendations apply, for example, to Toyota Aqua and Prius, Nissan Dayz, Honda N Box and N-WGN. However, this does not exclude the use for other engines, but also applies to modern passenger cars with gasoline or diesel engines, hybrid vehicles and those where the viscosity grade 0W-16, 0W-20 or even 5W-20 is recommended.
The first 0W-16 API SN engine oil
Honda tested with an oil that had almost the same properties of the 0W-16 before the new class release. At the same time, Toyota developed an engine oil under the name "0W-16," but without the approval of an organization such as SAE. Other Asian producers also produced similar low-viscosity oils, but without a typification as 0W-16 or an official release from an institute. Thus, Ravenol is and remains the first manufacturer to develop an officially certified oil with SAE 0W-16 viscosity and to offer it on the market today. For the market, this represents an enormous step and at the same time underpins Ravenol's prestige. After all, it was not a major car manufacturer that pioneered the new low viscosity with its own oils, but Ravenol.
