Car maintenance is the most important one annulus is of course the engine and engine maintenance care, the most important of course is to let it get the most effective lubrication, the proper use of improper oil can make the engine life extension, but also save fuel, or it will run counter to one's desire. Owners of the best weekly check oil habit, the remaining oil in the oil change and maintenance on the car, will be prepared against want.

At present, various brands on the market of oil products are hundreds of international brands,like Mobil subsidiary Esso, Mobil No. 1, Shell, Total, there are domestic brands, such as Compton, KunLun the Great Wall. From the price point of view, from tens of dollars to several hundred dollars or even a thousand dollars a barrel, all kinds of professional and varietyidentification and viscosity, the owners in the selection of oil greatly increased the difficulty of.Reporter random survey found that, although we all know the importance of the oil, but most of the owners are still in the stage of "oil blind".

The engine oil as lubricant, lubrication, wear not only play a role, and cooling, cleaning, rust proof, anti - corrosion, anti oxidation. Has very important effect on the quality of the quality of lubricating oil for normal operation of the engine. Good oil, especially the total synthesis of oil inengine protection, reduce the number of oil, can save fuel costs. Although the price of oil is two times more expensive than ordinary, is the best choice for many owners. If the selection of inappropriate or only momentary cheap to buy poor quality products, will cause the engine early wear and tear, reduce the service life of the engine, it will result in serious "cylinder, holding tile" vicious accident.

How to choose the oil

The owner must know the temperature environment for the use of vehicles in the oil, and then to buy oil according to the specification requirements of vehicle oil level and viscosity, when buying,carefully check the oil level on the packaging and labeling should be selected to meet the minimum viscosity, the requirements of the oil level and above. For example, in the area ofSichuan, the four seasons of a year under normal conditions, selected in line with the standard SAE15W-40 multilevel viscosity oil can. While Chongqing is hot in summer, the best choice for50 of the oil viscosity.

At the beginning of the thousands of kilometers of driving car called the running in period, thisstage will wear off parts of slight bulge, let the clearance of various moving parts more closely,more smooth motion. This period choose oil is even more important. In the run in period is generally used for viscosity grade of 15W/40 or 40 of oil in. Because the new car or engine overhaul, each part clearance uneven or too tight, need to adjust in the run in period, such as the selection of high viscosity oil with the gap is not very good, the surface is not easy to form a lubricating oil film and the formation of dry friction, resulting in excessive wear and tear, and even the emergence of tile burning, axle fault. Small viscosity oil for cleaning and cooling effect of good fluidity and can achieve better. If in the city car, because often traffic jam, which belongs to the loss of driving, is proposed to shorten the oil change mileage.

Don't forget to pack for oil

The vehicle driving a certain number of kilometers to do routine maintenance, replacement of oil and filter. But when the oil is in a barrel as a unit, the general will is slightly surplus oil. Don't forget to pack a leftover oil from me, spare. So, one or two months later, the lower liquid level oilmust be added, the owner can also use several maintenance save oil in an oil before "Shabu Shabu" engine, make oil more thoroughly

Oil do not mix

Sometimes found the car's oil shortage, need to add oil, this time must pay attention to is best not to add different brands or types of oil. Different brands of oil with additives have different mix,may cause the oil deterioration.
