Authorized services versus usual workshops

On the market there are very many choices when it comes to space repair our car. We decide against it at an authorized service center, which will find professionals who have a much greater knowledge about our car. This applies especially to the latest car models. There are also many possibilities to choose between the usual automotive workshops providing services such as replacement auto parts. This solution is certainly more beneficial for people who want to save money on car repair or car is already quite aged. The price difference between these two types of car repair really is often enormous.


Motor oil is a lubricant

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.

Is it worth donate cars to the workshop?

Repair workshop? This is certainly the most popular way to deal with technical problems on our cars. But we can always be sure that the repair goes as it should, and does not appear at this unforeseen problems? Of course not. That is why we should always use a reputable, proven workshop, which will guarantee us that made their work will be reliable and safe for our car. Only such places can make our car back on the road quickly, so sometimes you might even want to pay more for a decent service than to give yourself additional problems.
