Coolant Automotive A liquid which flows through a device to prevent the overheating of this device is called as coolant. It is commonly used in automotive and temperature control applications Coolant in engine is used to absorb the heat of the engine. It is used in radiator and circulated outside […]

Oil and Lubricant Oil is a relatively thick, viscous liquid produced from crude oil, plants, animals, or chemical synthesis. Oil and water don’t mix (usually). A lubricant is any substance that serves to reduce friction between moving parts. There is a lot of overlap between the two. Most oils are lubricants. The oil […]

Fluid-Viscosity Viscosity the use of oil which basically have minimal effect on the change of viscosity with respect to the changes of surrounding temperature. In lubrication, viscosity is the most important property or characteristic of an oil. Viscosity means the “thickness” of an oil, where specific application an oil requires […]

MULTI-GRADE OIL Multi-grade oil is oil that has viscosity modifier additives in it. These additives allow the oil to flow differently under cold and hot conditions. Multi-grade, or multi-weight oil is designated with two numbers. The first one is followed by the letter “W”. This first number indicates the viscosity […]
