Viscosity Temperature Chart Gear lubricant viscosity grades should not be confused with engine oil viscosity grades. A gear lubricant and an engine oil having the same viscosity will have widely different SAE viscosity grade designations as defined in the two viscosity classifications. For instance, an SAE 80W gear lubricant may have the Viscosity Index (VI) is a scale used to measure how much an oil's viscosity, or resistance to flow, changes depending on its temperature. Generally speaking, the less it changes, across a range of temperatures, the better. The scale of viscosity index is numerical in nature, with zero being the most susceptible to changes in viscosity.

Viscosity index improvers are just one of many high-tech additives that get of lubrication professionals consider an oil’s viscosity index when selecting a lubricant, according to a recent survey at machinerylubrication.com: Comparing the 95 VI oil to the 150 VI oil, there is a 236-percent difference in viscosity at minus 20 degrees C and a minus 25-percent difference at 100 degrees C.

In 10W-40 oil, for example, the two numbers mean that it’s a multi-viscosity oil. The 10W is an index that refers to how the oil flows at low temperatures (in Winter); 40 refers to how it flows at high temperatures. To find out which viscosity to choose for your vehicle, look in your owner’s manual for an oil viscosity chart. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. Viscosity means a fluid's resistance to flow. In motor oil, it's rated at zero degrees Fahrenheit (represented by the number preceding the "W" [for winter]) and at 212 degrees (represented by the second number in the viscosity designation). Motor oil thins as it heats and thickens as it cools. The viscosity of an oil is measured by its resistance to flow. There are two numbers that define the viscosity of an oil. The first number ends with the letter 'W', which stands for Winter. This measurement is related to how an oil flows when it is cold, such as at engine start-up. The main requirements for an engine oil are defined temperature-viscosity properties, protection against wear and corrosion, keeping the engine clean, holding particles like soot or abrasives in suspension, yield strength under compression and many more. Temperature impacts the flow properties of engine oil. Engine oil is available in different The viscosity index depends on the time needed to flow from the hole. All lubricants have a practical limit on operating temperature. Viscosity is understood as the resistance of a liquid to flow at a certain temperature. This is an important factor in choosing the right oil. motor oil viscosity chart . By : www.quora.com.
