![]() PAO oil is widely used in all fields of industry because introduces an applied research method for viscosity conversion of lubricating oil at different temperatures, which can realize the rapid calculation of viscosity index of oil with pour point greater than 50Â☌.Ībroad, the Soviet union scholars. Keywords:PAO kinematic viscosity density temperature This formula can be used to predict the viscosity of PAO oil in a certain range of temperature. The newly established viscosity-density- temperature formula can better describe the relationship between viscosity, density and temperature of PAO oil in the range of 30Â☌-110Â☌. The results show that the viscosity and density of PAO lubricating oil decrease with the increase of temperature, and the higher the density of PAO oil, the higher the kinematic viscosity of PAO. The relation on viscosity-density-temperature of PAO oil was established. The relationship between viscosity, density and temperature of PAO oil was analyzed. Many of our products are also available in very convenient oil change kits that provide everything you need to change your oil.Study on the Relationship Between Kinematic Viscosity, Density and Temperature of Lubricating Oil PAOġLijun Yang,2Yanshuang Wang,3Erqiang Wang,4Feilang Ningġ234Mechanical Manufacture and Automation 1234Tianjin University of Technology & Education 1234Tianjin, ChinaĪbstractUsing the oil products kinematic viscosity tester and petroleum products density tester the kinematic viscosities and densities of five PAO oils with different initial viscosity were Fortunately, you can find all types of oil on Power Oil Center, including Factory Racing Parts, Red Line, Craftsman, PennGrade 1 and Royal Purple. Using oil with the wrong viscosity can also lower fuel economy and lead to higher wear on engine parts. Likewise, in the hotter weather, oil with a low viscosity may run too thin and won’t provide the lubrication and cooling required. In worse-case scenarios, your engine can be damaged by using the wrong viscosity oil. Using oil with too high of a viscosity will increase the wear on engine parts leading to breakdown. Those in cold climates know that it is sometimes difficult to start a car when temperatures drop. In cold temperatures, oil with too high of a viscosity can thicken and it’s harder to get it to circulate through the engine. Viscosity helps determine how well the oil will protect your engine by lubricating, cooling and cleaning. When determining which grade of oil to use, refer to your vehicle’s owner manual. As temperatures rise, an engine oil with a higher kinematic viscosity is a better choice. The higher the second number, the more suitable it is for use in high temperatures. For example, a 10W-40 grade oil will provide lubrication and protection at high temperatures than a 10W-30. The second part of the SAE viscosity grade is the high-temperature viscosity, also known as kinematic viscosity. It is why the “W” is placed here in the description. A 5W-30 or 0W-30 oil will be more effective in cold temperatures than a 20W-40. The most critical moment is at startup when the engine is cold and oil must get to critical engine parts rapidly. Dynamic Viscosity is how much force is needed to move an object (such as a piston rod) through the fluid.Īn engine has a lot of moving parts. This determines the oil’s low-temperature dynamic viscosity. Measurement of the low-temperature viscosity is done through a Cold Crank Simulator Test. The second number correlates to the high-temperature viscosity – the -30, for example in a 5W-30 grade. The low-temperature viscosity is the winter grade and is the “xW” at the beginning of the sequence. The viscosity grade of oil is set by the Society of Automotive Engineers (SAE). Our experts have done the research to find the best oils…and the right oil… for your vehicle. Not only will it include engine oil specific for your car or truck, but you’ll also get a premium oil filter, a crush washer and a funnel. An easy way to make sure you’re getting the right oil for your vehicle is to use an oil change kit from Power Oil Center. Knowing the correct viscosity oil for your vehicle maximizes both protection and performance. Having an oil with the right viscosity will give your engine the best protection. Obviously, if you pour a bottle of water, the water will come out way quicker than if you dumped out a bottle of molasses.Īnimation courtesy of the TeachEngineering YouTube Channel Viscosity, in the very simplest of terms, is the measure of how a liquid resists to flow.įor example, water has a much lower viscosity than molasses. The viscosity of the oil is critical in how well it flows through your engine and gets to the critical components.
