premium oil for Opel 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.

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.
Servicing cars after accidents
One of the most common causes of damage to the cars are all sorts of road accidents. While serious incidents of road servicing of such cars may be even unprofitable, because the costs arising from the repair would exceed the value of the car. Servicing a car after an accident is very difficult not only because it is usually the failure of such an event is a lot of car parts. It is also complicated because sometimes resulting dents and other damage to prevent, for example, look inside the hood to find all the problems with the car. On the other hand, the repair may be necessary, because the car is often essential for benefiting people transportation.
