Oil Filter

Oil is a kind of lubricant, which is made up of two parts of base oil and additive according to certain proportion. Base oil is the main component of oil, which determines the main characteristics of oil; Additives are organic compounds or a few inorganic substances (such as graphite, molybdenum disulfide, etc.) added to improve the lubricating properties of the base oil. Oil is the heart, and the oil filter is the best "goalkeeper" of the heart. It filters all kinds of impurities in the oil. Prevent impurity to cause wear and tear to engine. But "goalie" also have one day of retired, if do not replace machine filter for a long time, can make machine filter because of dirt and partial clog, contaminant flows directly into engine, aggravate machine wear; If you only change the oil but not the machine filter, the contaminated oil in the old machine filter will re-enter the oil circulation. It can be said that if you do not change the machine filter, your oil will be changed in vain! Experts stressed: generally every 5000 km of oil should be changed, each time oil should be changed to filter machine!
