This increases fuel consumption

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.

Express service stations

When the car breaks down, and we need it for now, you should look for the plant, which will provide us with a quick repair. Such Express repairing faults now offers multi-site vehicle repair, so we should easily find a deal, which would be suitable for us. But what we need to know when deciding on such a solution? The main issue is of course the cost of such repairs, which will be much larger than traditional services in this field. Many people are aware that it pays us to spend more for the same service, but when the time is very important to us, it is better to invest a set amount, than to make yourself more trouble by trying to save. In such situations, very easy to make a mistake that could put us in a difficult situation, which hurt us.


Car repair at an authorized service

Although most people decide to order auto repair shop in the ordinary, it is not missing and those who prefer to do the servicing of the vehicle at an authorized site. Why opt for the second option? Despite the fact that we have to expect a much higher repair costs, however, this choice is often a good solution to this situation due to the fact that such a service is often the only place where you can fix a new car. These services also provide genuine auto parts, which can be much more favorable for our car than the alternatives. Moreover, an authorized service center we can expect a professional car diagnosis at a very high level.
