The oil filter is used in order to avoid early engine damage. During those days when the oil filter was not yet invented, car owners had to have oil changes very frequently that it became very costly and inconvenient. But because of the fast and relative car technology these days, the use of air filters has become common to all types of vehicles. Undeniably, automotive oil is a crucial vehicle component and is considered to be the lifeblood of the engine. Ideally, the oil must be free from harmful particles to improve the quality, performance and life of the engine.

In general, the oil filter is found at the side of the engine block in the lower, bigger part of the engine. The fuel pump circulates the oil through the engine, and the oil passes through the oil filter every time it circulates. The oil filter offers protection to the engine by catching the big particles contained in the oil, which when allowed through the engine can possibly damage the system or some of its vital parts. It is not a common knowledge for car owners that fuel filter also lubricates some of the moving engine parts. How? It's a good thing you asked. So here's actually what happens.

The oil actually drains into the bottom of the engine hence the moving parts of the engine on top are left without enough lubrication. You must understand that lubrication is necessary during the operation of the vehicle. Now, the oil filter provides that lubrication in such a way that the small amount of oil left in it will circulate rapidly into the top of the engine at the first couple of seconds when the car is started, thus restoring enough lubrication as early as possible.

There are generally two types of air filters used. They are the primary filter or the full-full filter and the secondary air filter which is also know as the by-pass filter. In normal operation, a hundred percent of the engine oil passes through them, although they allow passage of tinier particles since they must work without the introduction of a lot of restrictions to prevent oil from flowing into the engine during cold start-ups.

As part of automotive maintenance, old oil filter must be replaced since in the fullness of time, it will become defective.
