On the one hand, each owner of the vehicle is aware of mandatory timely procedures for the replacement of motor oil. However, on the other hand, not all understand the importance of proper selection of oil in accordance with Engine type, seasonal and operational conditions. But a variety of options in connection with different characteristics, viscosity and density, as well as the presence of additives, modifiers and additives, allows for selection of oils most accurately. The importance of correct choice is that the bug can cause substantial damage to the engine. For more information see John Brown. Due to improper or insufficient lubrication components and assemblies will be hard to wear that may even lead to jamming the motor. Fairly common misleading arguments is the reluctance of modern high-quality motor oil in vehicles older generations. Is justified that the car was designed and produced, when synthetic oil was not yet.
However, the use of modern Motor oils with similar characteristics will provide "the heart of the car" more protection due to modern additives that can generally extend its life and increase the reliability indices. What is with regards to the parameters that should be selected motor oil, then in the first place will be indicators viscosity. That's viscosity determines the properties of the oil to remain fluid and lubricating all sliding surfaces, and does not solidify even at extreme temperature loads. After all, it should be noted that the temperature range engine is quite wide. When engine temperature equal to the environment, and in winter it can be -40 C, performance at 90 C on the dashboard report only the coolant temperature. While the motor oil can work in the engine, where the temperature dostigaet150-160 C. Temperature Motor oils will depend on the mode of operation of the engine, but rather on the number of turns at high torque, which can be sufficiently high during sudden overtaking, driving up the hill and with the load. An important characteristic of motor oil is its ability to uniform lubrication mechanisms in different temperature ranges, which is achieved by the addition of various modifiers to ensure stable operation. Also additives used in modern Motor oils may form the protective tungsten or molybdenum film on the surface of metal parts. It is therefore timely replacement and proper selection of engine oil will not only ensure the stable operation and motor protection, but also can increase the capacity and lifetime of the units of the automobile.
