A huge amount of liquid is poured in each car. Part of it is in the engine, part in the radiator, pipes, part in other containers. Its purpose is very broad. First of all, this is cooling the cylinders, because without the coolant the engine will simply collapse. In addition, there is also brake fluid, without which it is also impossible to drive cars, since the vast majority of brake systems are hydraulic. This also includes antifreeze, since it is also quite important in operation.
In our article, we will talk about a liquid such as oil. There are various types and varieties, each of which has its own properties. They determine the purpose. The main property is viscosity. Oil is replaced due to the fact that it loses its lubricating properties, namely, it becomes liquid. Oil is poured into the engine, into the gearbox, into the drive axle. Oil changes are carried out in all of these containers.
It is necessary to monitor the purity of the oil. Particles of dust and other debris that adhere to the oil film constantly get into the engine with air. It is then washed off and enters the engine crankcase. From there, the oil is taken by the oil pump, a mesh is installed on its intake, but it protects only from large debris.
Now all the dust, which previously was not dangerous, has become large pieces of dirt that can even clog high pressure channels. An oil change helps to avoid this. In addition, the oil industry is now quite widely represented, and offers consumers flushing oils that can eliminate the remnants of this dirt left over from past oil.
Changing the gearbox oil is not so common. On average, through one MOT. But we must remember that if in mechanics you can change the oil yourself, the oil change in the box is automatic only at service stations that have special equipment. It allows you to rinse the box, since dirty oil is absolutely unacceptable for the machine. A complete oil change in the automatic transmission can be quite an expensive operation, since here payment is made for the oil used for flushing. This is done under high pressure, so it is very important in the machine that all the seals are in good condition.
As for the driving axles, it uses gear oil, which has a high viscosity, which allows it to form a denser film on the mating parts.
In conclusion, back to the engine, because, as is customary, this is the heart of the car. Timely replacement of oil and filter elements can extend the life of the engine much more than most motorists believe. The new oil retains its properties even at the highest temperatures, therefore, at lower temperatures, operation becomes more productive. Oil that has passed its mileage becomes liquid, it simply drains from the parts, especially at elevated temperatures. But when replacing, it is worth paying attention to whether there were leaks, since debris that could get into the seals was simply washed.
