The type of vehicle or other unit for which the oil is designed. Different types of cars have different features, which are taken into account when developing motor oils:
—
Passenger cars. Passenger cars are characterized by high speeds at low loads, which led to the use of engines with relatively low torque.
—
Trucks. For trucks, high speed is of secondary importance, but they have to deal with heavy loads and the engines must "pull" accordingly.
—
Motorcycles, scooters, snowmobiles. Among two-wheeled vehicles, two-stroke engines (see “Engine”), whose requirements for oil characteristics differ from four-stroke engines, are very popular. In addition, motorcycle engines (including four-stroke engines) are in most cases equipped with the so-called. “wet clutch” (as opposed to the dry clutch used in cars), and also operate at higher speeds.
-
Water transport. Most engines installed on motor boats, boats and yachts are two-stroke. However, they operate in different modes than motorcycle ones (in particular, they use water cooling instead of air), which necessitated the use of specialized oils.
—
Agricultural machinery. Agricultural machinery predominantly uses diesel engines; At the same time, the speed of movement for such units is not c
...ritical, but high traction and resistance to loads, on the contrary, are of decisive importance.
— Gasoline tools. Engines for gas-powered tools are in many ways similar to those described above for motorcycles - in particular, they are often made two-stroke.
— Flushing. Low-viscosity motor oils with a special package of detergent additives based on potent chemicals, used to maintain the internal components of the power unit in proper cleanliness, remove varnish deposits, accumulated dirt and slag, and neutralize acids formed in the engine. Flushing compounds are recommended for use when switching from one oil to another (based on base, viscosity or manufacturer), when purchasing a used car with an unknown service history, when there are visible carbon deposits under the valve cover, and under severe engine operating conditions.
Please note that recommendations for use are not categorical: for example, some chainsaws allow the use of motorcycle or even automobile oils, and for trucks, “agricultural” oil may be suitable. On the other hand, compliance with a general purpose does not guarantee that the oil will be suitable for a particular unit: for example, formulations for gasoline engines cannot be filled into a diesel passenger car. So this parameter is not final, but only preliminary: having decided on the purpose, you need to select a specific oil based on more detailed characteristics (engine type, SAE indicators, manufacturer tolerances - see below).An engine oil quality standard that the car manufacturer Opel and GM consider essential for correct operation when used in the engine of their vehicles.
