Rational selection of engine oils is an essential condition for long-term operation of the engine of any car. Therefore, this event should be given special attention.
Today, there are a huge number of different classifications of motor oils. The main parameters that underlie them are the following:
The most common of all is the classification of motor oils by type:
- Mineral engine oils. Their big advantage is their relatively low cost. It should be remembered that the range of use of these oils is not very wide. Production is carried out by blending residual and/or distillate oils.
- Synthetic motor oils. The main advantage is the ability to use in almost any situation. But their cost is quite high. This is due to the fact that high-quality components are used in the production process, as well assophisticated equipment.
- Semi-synthetic engine oils. Their use is very beneficial for both the car and its owner. Such motor oils are relatively inexpensive, help reduce fuel consumption, and also have good performance characteristics. However, they can be used in all types of engines.
The classification of motor oils according to their viscosity (SAE classification) is quite common. According to this indicator, they are all divided into the following types:
- all season.
Winter-type motor oils are marked using the letter "W" (0W, 5W, 10W, and so on). The larger the number before the letter, the higher the viscosity. As for summer motor oils, they are completely marked with numbers alone according to a similar principle. All-weather oils must have 2 digits in their full name. In this case, the first of them displays the viscosity of the oil at low temperatures, and the second - dynamic viscosity at 150oC and kinematic at 100oC.
Apparently, the most difficult is the classification of motor oils by quality. Its foundation was laid back in 1947, when the so-called API gradation appeared. It has been updated many times. The current classification of this type dates back to 2001. According to her, all engine oils are divided into 2 large categories:
- service: includes 9 classes;
- commercial: includes 10classes.
All engine oils in the servise category are designed for use in those engines that run on gasoline. As for commercial oils, they are designed for diesel power units.
There is also 1 more classification of motor oils by quality level - ACEA. It divides all types of oils into 3 groups: A, B and C. The first of them includes 3 types: A1, A2 and A3. They are designed for engines running on gasoline. The second group is already divided into 4 types: B1, B2, B3 and B4. Such motor oils are usually used in light diesel engines that are installed on cars and vans made on their basis. The third group also includes 4 types of oils: C1, C2, C3 and C4. They are used in heavy diesel engines that are equipped with trucks.
Today, almost any driver who has a we alth of experience behind him knows perfectly well what the decoding of the API SL CF testifies to. This applies directly to engine oils, and among them there are different options - for diesel and gasoline engines, including universal oils. Beginners can simply get confused in this combination of letters and sometimes numbers
API specifications are developed by the American Petroleum Institute. The first API motor oil specifications were published in 1924. This institute is a national non-governmental organization in the United States
Automotive oils 5W30: rating, characteristics, classification, declared qualities, advantages and disadvantages, reviews of specialists and car owners
Every car owner knows how important it is to choose the right engine oil. Not only the stable operation of the iron “heart” of the car depends on this, but also the resource of its operation. High-quality oil protects mechanisms from various adverse effects. One of the most popular types of lubricants in our country is oil with a viscosity index of 5W30. It can be called universal. The 5W30 oil rating will be discussed in the article
The article is devoted to the classification and labeling of motor oils. SAE, API, ACEA and ILSAC systems reviewed
Beginner drivers face many questions when operating their first car. The main one is the choice of engine oil. It would seem that with today's product range on store shelves, there is nothing easier than choosing what the engine manufacturer recommends. But the number of questions about oils does not decrease
