What does a regular oil change do?

Every car is filled with a huge amount of liquid. 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 the cooling of the cylinders, because without 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 such a liquid as oil. There are various types and varieties of it, each of which has its own properties. They determine the destination. The main property is viscosity. An oil change is made 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 these containers.

You need to keep the oil clean. Air constantly gets into the engineparticles of dust and other debris that adhere to the oil film. It is then washed off and enters the crankcase. From there, the oil is taken in by the oil pump, a mesh is installed on its intake, but it only protects against large debris.

Now all the dust that was not dangerous before has become large pieces of dirt that can even clog high pressure channels. Changing the oil helps prevent this. In addition, the oil industry is now quite widely represented, and offers the consumer flushing oils that are able to remove the remnants of this dirt left over from the old oil.

Change the oil in the gearbox is not done so often. On average, after one MOT. But we must remember that if in mechanics you can change the oil yourself, then the oil change in the automatic box is carried out exclusively at service stations that have special equipment. It allows you to flush the box, since dirty oil is absolutely unacceptable for a machine. A full oil change in an automatic transmission can be quite an expensive operation, since here you are charged for the oil used for flushing. This is done under high pressure, so it is very important in the machine that all seals are in proper condition.

As for the drive axles, transmission oil is used here, which has a higher viscosity, which allows it to form a denser film on mating parts.

BConclusion 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. The oil that wastes its mileage becomes liquid, it simply flows off the parts, especially at elevated temperatures. But when replacing, you should pay attention to whether there are any leaks, because the debris that could get into the seals was simply washed out.
