oil for Dacia Replacement of damaged parts of the vehicle
Repair the car after the accident must be preceded by an accurate determination of cause resulting incident, otherwise the driver will be exposed to the fact that after some time again cause a car accident because of this that drives a defective car. The reason for the resulting failure can be either a technical defect, for which the driver is not responsible and long-term use of motor oils of poor quality. Therefore, when car repair is done, exchange the damaged parts, and selects a good engine oil, the driver should now use. Allowing the car to re-use will be made only after a thorough verification of the state of the already made repairs.
Positive Crankcase Ventilation
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.

Entrust family auto skilled in the art
The family car should be, above all, big and safe. Therefore, deciding to buy a car, which will serve all members of the household, usually choose the model that easily accommodates childish seats, and the luggage trolley and of course complex. No less important is the issue of security. But often we forget that a lot depends on us - not only when it comes to careful driving, but also in terms of servicing the car. Faulty brakes may yet lead to a real tragedy, like eg. Oil leak, which is a threat also for other road users. To avoid dangerous situations, it is therefore necessary regular servicing cars - after all, safety is paramount.
