What is a oil filter?

An oil filter is a filter designed to remove contaminants from engine oil, transmission oil, lubricating oil, or hydraulic oil. Their chief use is in internal-combustion engines for motor vehicles (both on- and off-road ), powered aircraft, railway locomotives, ships and boats, and static engines such as generators and pumps. Other vehicle hydraulic systems, such as those in automatic transmissions and power steering, are often equipped with an oil filter. Gas turbine engines, such as those on jet aircraft, also require the use of oil filters. Oil filters are used in many different types of hydraulic machinery. The oil industry itself employs filters for oil production, oil pumping, and oil recycling. Modern engine oil filters tend to be “full-flow” (inline) or “bypass”.

Bypass and full-flow

Full-flow

A full-flow system will have a pump which sends pressurised oil through a filter to the engine bearings, after which the oil returns by gravity to the sump. In the case of a dry sump engine, the oil that reaches the sump is evacuated by a second pump to a remote oil tank. The function of the full-flow filter is to protect the engine from wear through abrasion.

Bypass

Modern bypass oil filter systems are secondary systems whereby a bleed from the main oil pump supplies oil to the bypass filter, the oil then passing not to the engine but returning to the sump or oil tank. The purpose of the bypass is to have a secondary filtration system to keep the oil in good condition, free of dirt, soot and water, providing much smaller particle retention than is practical for full flow filtration, the full-flow filter is still used to prevent any excessively large particles from causing substantial abrasion or acute blockage in the engine. Originally used on commercial and industrial diesel engines with large oil capacities where the cost of oil analysis testing and extra filtration to extended oil change intervals makes economic sense; bypass oil filters are becoming more common in private consumer applications.[3][4][5] (It is essential that the bypass does not compromise the pressurised oilfeed within the full-flow system; one way to avoid such compromise is to have the bypass system as completely independent).
