consequences of using old car tires

The reasons for the small car breakdown can be really mundane. Inexperienced drivers do not even realize this, how can they lead to a failure in his car. Meanwhile, the consequence of the use of motor oil of poor quality may be overheating or cooling of the engine, by which it will begin to function worse and worse, and eventually refuse to obey the driver. There should also save on oil brake, because its deficiencies in the car can lead to the fact that the brakes will react with a delay, and this situation is particularly dangerous for the driver and other road users. On the other hand, perhaps the largest number of drivers are aware of what may be the consequences of using old car tires.


Why do car repairs are readily carried out even by amateurs?

As you know, car servicing and replacement of parts is often very expensive. It is no wonder that more and more people try their own or with help from friends or literature available to carry out such repair. If our car really should now be scrapped, there are several possibilities for its development. Popular is the sale of car parts that can be removed from an unused car. There is a considerable demand for this type of offer. Often used parts are much more readily purchased by the owners of others, especially older car models.


Coating metal parts

Motor oil is a lubricant used in internal combustion engines, which power cars, motorcycles, lawnmowers, engine-generators, and many other machines. In engines, there are parts which move against each other, and the friction wastes otherwise useful power by converting the kinetic energy to heat. It also wears away those parts, which could lead to lower efficiency and degradation of the engine. This increases fuel consumption, decreases power output, and can lead to engine failure.

Lubricating oil creates a separating film between surfaces of adjacent moving parts to minimize direct contact between them, decreasing heat caused by friction and reducing wear, thus protecting the engine. In use, motor oil transfers heat through convection as it flows through the engine by means of air flow over the surface of the oil pan, an oil cooler and through the buildup of oil gases evacuated by the Positive Crankcase Ventilation (PCV) system.

In petrol (gasoline) engines, the top piston ring can expose the motor oil to temperatures of 160 °C (320 °F). In diesel engines the top ring can expose the oil to temperatures over 315 °C (600 °F). Motor oils with higher viscosity indices thin less at these higher temperatures.

Coating metal parts with oil also keeps them from being exposed to oxygen, inhibiting oxidation at elevated operating temperatures preventing rust or corrosion. Corrosion inhibitors may also be added to the motor oil. Many motor oils also have detergents and dispersants added to help keep the engine clean and minimize oil sludge build-up. The oil is able to trap soot from combustion in itself, rather than leaving it deposited on the internal surfaces. It is a combination of this, and some singeing that turns used oil black after some running.

Rubbing of metal engine parts inevitably produces some microscopic metallic particles from the wearing of the surfaces. Such particles could circulate in the oil and grind against moving parts, causing wear. Because particles accumulate in the oil, it is typically circulated through an oil filter to remove harmful particles. An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type.
