Scorching summer, seasonal high viscosity lubricant replacement became the majority owner of one of the key summer conservation. However, the reporter recently discovered a strange phenomenon: the lack of understanding of the lubricating oil viscosity, some car owners to replace the excessive pursuit of high viscosity oil, even the oil pour out pro "hand" verification viscosity; there are still some owners to replace After lubricating oil pressure gauge is found to increase, but absorbing film of sludge has increased, the power was significantly reduced. I want to take care of the car, but did not expect to increase the burden on the car, make your car "physically and mentally exhausted." This makes many owners puzzling: how to choose the lubricant in the end the summer? 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 increased friction, Zhengzhou will have to consume more fuel oil, resulting in a huge waste of energy. It is understood that in foreign Zhengzhou wholesale of lubricants, low viscosity lubricants 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 Henan wholesale lubricants, do not use too much oil viscosity, but can not believe the bigger the better viscosity. 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 lubricating oil wholesale market in Zhengzhou, a small viscosity of the lubricant used wherever possible. 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 reasonable limits prescribed in the 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, such as sensor broken, the oil block and so forth. Never saw the low oil pressure gauge, desperately high viscosity lubricant selection. Zhengzhou lubricants market in which lubricating oil _ _ Zhengzhou and Zhengzhou and by-Run-Run Trading Company.
