Automotive oil pumps are primarily used to pump lubricating and cooling oil within the engine of a vehicle. Every vehicle needs an oil pump to lubricate the internal components, namely, pistons, camshaft, bearings, crankshaft, etc. Without lubrication, friction, wear, and tear will cease the engine and cause damage to the internal components. Hence, a lubricating oil is circulated at high pressure. Lubrication systems, thus oil pumps, vary in accordance with the usage of the automobile, such as an off road vehicle, a normal passenger car, or a heavy commercial vehicle.
