The Oil used for lubrication of the engine in the car. It is different kind. The choice of type depends on the engine and all of the conditions in which the vehicle is operated.
Today, motor oils are divided into three grounds: by type, by viscosity, by purpose and quality.
1. Type. In this case, distinguish between mineral, synthetic and semi-synthetic oil. The mineral form is obtained by mixing the distillate and residual base oils. It has a low cost and is suitable for most motors. The synthetic type is more expensive, but it has a high performance. This oil can be used in any climate and during any season. Semi-synthetic type is obtained by mixing the previous two, so it has better performance than the mineral option, and lower price than synthetic. This oil can be used for all types of engines.
2. Viscosity. This is the most important indicator. It is based on classification of oils SAE J-300, it has five summer and six winter options. The last recorded letter “w” (25w, 20w, 15w, 10w, 5w, 0w). The smaller the first number is the oil viscosity below the sub-zero temperatures and easier cold start of the engine. For example, if the viscosity is 0w, the pump will have the ability to pump oil at a temperature of 35 °below zero, and the starter can spin the engine at temperature - 30 °C . The measure of viscosity equal to 3.8 mm2/s. If the SAE viscosity grade – 25W, the pumpability possible at - 10°C , and provorachivayut – in - 5°C (kinematic viscosity is equal to 9.3 mm2/c). Summer oils are designated by the numerals 60, then 50, 40, 30 and 20. There are year-round products, which has a double designation: the first – winter, second – the summer grade (SAE 10W-30, for example).

3. Classification of oils by destiny divides them into those that are used for gasoline engines and those used for diesel. There are also multi-purpose products. The quality they all have either a low or high level. For the purpose of motor oils is classified by several systems: American and European, which determine the scope of their use. The European system is considered more strict. Depending on the properties of oils (anti-wear, anti-oxidation, anti-corrosion, detergents and others) set their membership to a particular class.
The API system divides the oil into such categories: “S” for petrol engines and “C” for diesel.
Classification of oils by this system is as follows:
- for petrol engines – SM (2004), SL (2001) and SJ (1996), SH (1993), SG (1989);
- for diesel – CI-4(2002), CH-4 (1998), another CG-4 (1995), CF (1994) and, of course, CF-2 (1994), CE (1987), CD II (1987).
The Letters after S and C denote the quality of the product. It is better if the letter is further down the alphabet. Today oil marked “B” and “A” are not produced, as they have low operating performance.
The European system in more detail characterizes the properties and the area where used motor oil. Classification ACEA has exactly three categories: «And» for gasoline and “In” and “E” for diesel engines. Since 2004, a class “C”, oils which are suitable for both types.
Classification of oils according to the European system as follows:
- for gasoline engines (cars and vans) – A5-2002 , A4-98, A3-96, and A2-96, A1-96;
- for diesel (cars and vans) – B5-2002, B4-98, B3-96, B2-96, and finally B1-96;
- for engines of trucks and trains – E5-99, E4-99, E4-98, E3-96, E2-96, and E1-96.
The higher the number in the marking, the oil (automotive) is of higher quality. Year specified with a hyphen, is the year of approval.
Each motorist can choose a motor oil that it sees fit. However, in his preference for it, one way or another, will be based on the above classification.
