The Impact of Engine Oils on Modern day cars! Motor oils keep engines running smoothly
The simple task of an engine using petrol cannot be completed without an appropriate engine lubricant. Car engines involve hundreds of moving parts, both small and large. It also includes a huge amount of friction going on inside the average car’s engine, with strong metal components contacts which constantly produce friction. Oil Lubricants are remarkable fluids. The viscosity is one of the most significant physical properties of a lubricant. The way in which it varies with temperature, shear rate and pressure determines to a great extent how the lubricant performs in an engine. SAE J300 is a standard that defines the viscometric properties of mono- and multigrade engine oils. Take multigrade oil SAE 15W-40 as an example. The first number “15” before the letter “W” which stands for winter, represents the cold temperature viscosity grade. SAE J300 defines the limits of “15W” grade. The number “40” stands for high temperature viscosity grade, and again SAE J300 defines the ...
