Thumbs Up: 3 Videos to Watch Wide-Span Multigrades What exactly is viscosity, and what’s the advantage of multigrade gear oil? Viscosity is one of the most important properties of oil in maintaining a lubricating film between moving parts. The easiest way to think about viscosity is that it’s the thickness of the oil. The thicker an oil is, the higher its viscosity. Watch this video for more information on viscosity and wide-span multigrades. Cold Weather Flow of Axle Oils When the weather turns colder, the viscosity of oil tends to increase and it doesn’t flow as easily. At extremely low temperatures, the oil barely flows at all, reducing its ability to lubricate and protect the axle components. Watch this video for more information on the cold weather flow of axle oils.
