Basics About Engine Lubrication

Lubrication plays a key role in the life expectancy of an engine. Without oil, an engine would succumb to overheating and seizing very quickly. Lubricants help mitigate this problem, and if properly monitored and maintained, can extend the life of your motor.

The process of best engine lubricant in an internal combustion engine begins in the sump, commonly referred to as the oil pan. From here, the oil is pulled through a strainer, by the oil pump, removing larger contaminants from the mass of the fluid. The oil then goes through the oil filter. It is important to note that not all filters perform the same.

A filter’s ability to remove particles is dependent upon many factors, including the media material (pore size, surface area, and depth of filter), the differential pressure across the media, and the flow rate across the media.

Oil is pumped through passageways to the various components of the engine such as the cam, main bearings, rod, pistons, etc. Gravity then pulls the oil back down to the bottom of the motor to drain back into the sump, and the cycle repeats.

To appreciate the full impact of the engine lubrication process, you must understand how oils are formulated. All engine oils have two components: additives and base oil. The total volume of additives in motor oil can range from 20 to 30 percent, depending on brand, formulation, and application. These additives can enhance, suppress or add properties to the base oil.
