The importance of oil
Engine oil is as important as blood to the heart. It contains a variety of additives, can effectively protect the important mobile components of the engine, to ensure the normal operation of the engine.
Lubrication: the main function of oil is lubrication, which can be formed on the surface of the metal parts of the engine oil film, reduce the wear of metal surfaces.
Clean: the decomposition of engine used in the process of sludge and sediment, keep clean inside the engine.
Rust: and the use of the process in the engine to produce acid substances, and the formation of anti rust and anti-corrosion layer, to avoid corrosion of metal parts due to oxidation and corrosion.
Seal: seal the gap between the piston and the cylinder, so that the fuel burning fully, improve fuel efficiency.
Cooling: the high temperature caused by the abrasion of the dispersed engine to protect the various parts of the engine. Lubricating oil in the process, additives were gradually consumed, produced combustion pollutant mixing and oil mixed with sludge, deposition, for a long time, the dirt will not only accelerated engine wear, will also cause the engine rust corrosion, heat is not smooth and other serious consequences. Therefore, the timely replacement of oil is the best protection for the engine.
Oil change cycle
When buying a car, car manufacturers will with the car comes a car repair and maintenance manual, listed in the manual vehicle mileage of oil / oil change period, the majority of vehicles in the 5000-10000 km. To reach the general provisions of the oil change mileage should be oil, part of the high-grade vehicles such as, when reaching the mileage of oil inside the car will oil prompt appears.
Actual driving, road condition, and oil quality, will affect the oil cycle. Such as long-term in urban driving, car parking, starting frequently, increased engine wear, and to speed up the oil pollution, it is necessary to cut the oil change period.
Owners can regularly on the car's oil were detected using the dipstick dip in a little oil on the fingers, such as oil is black, very thin and containing gravel, at this time the oil deterioration, should be replaced immediately.
Oil and oil change
Filter is of various impurities in oil filtering and prevent impurities on the engine caused by wear, such as term does not replace the filter, the filter due to dirt and partially blocked, pollutants flowing directly into the engine, aggravate the wear of machine parts; if only change the oil without replacing the filter, old filter residue is oil pollution will re enters the oil in circulation, so, the experts stressed that: every oil change should replace filter.
Recommended oil, filter, about 5000 kilometers per ride will be replaced once, air filter and gasoline (diesel) oil filter every ten thousand kilometers to be replaced.
