Use oil viscosity is too large, another drawbacks is energy. Since the viscosity is too large, mechanical friction between the friction surface increases, in order to overcome the friction increases, will have to consume more fuel, resulting in a huge waste of energy. It is understood that in foreign countries, low viscosity lubricating oil has become an international trend. In China, the lubricating energy efficiency Although there is no mandatory requirement, but low viscosity will be the future trend of development. Therefore, do not use too much oil viscosity, but can not be considered the greater the viscosity, the better. Summer how to choose the proper viscosity grade selection of lubricants so it summer? In ensuring lubrication conditions, when used according to the temperature range, the engine temperature and the actual condition, as the choice of small viscosity oil. On condition better, wear a relatively small engine, you can choose a small viscosity oil, while the wear and tear is more serious, the gap has been relatively large engine, may be appropriate to choose a slightly larger viscosity oil. Further, since the temperature difference between summer and winter is relatively large, summer is generally low oil pressure gauge. However, as long as the wholesale of lubricants in a reasonable range specified on the Zhengzhou factory driving manual, are a normal phenomenon, the majority of owners do not need to panic for that matter. If high or low oil pressure gauge bizarre, than normal deviate too much or not within a reasonable range, then you need to thoroughly check to see if it is what's wrong with the engine lubricating oil wholesale center in Zhengzhou, such sensor is broken the oil passage blocked, and so on. Never saw the low oil pressure gauge, desperately high viscosity lubricant selection. For bearing lubrication, the flexible operation to meet the bearing lubricating oil soap fiber structure (ie thickener) should have a smooth shape, no particles to ensure that the bearing can be smooth, flexible operation lubricants wholesale Which Zhengzhou and does not produce noise, precision bearings for it should have the following characteristics: 1) oil structure smooth, uniform, particulate-free 2) oil lubricants colloidal stability good Zhengzhou wholesale agents, sub-oil moderate. 3) lubricating mechanical stability is good, can guarantee long-term work, structural fat is not prematurely destroyed 4) low mechanical impurities. Mechanical impurities is the main cause of noise and wear, because they can not make the bearing well balanced operation generates vibration.
