are parts that constantly need lubrication, to keep them in good running



condition. It needs that the lubricant be kept clean, as contaminants can

cause excessive wear and tear. The oil filter is the device used for this

purpose.

Oil filters are located at the side of the engine block. They are key

components in safeguarding your Volvo engine. How does this work? As the oil

pump circulates the oil throughout the engine, the engine oil passes through

the oil filter. The oil filter then goes to work, blocking large particles

that might damage the engine. This way, it protects the engine from harmful

substances.

Oil filters for automobiles also protect the engine by preserving a small

amount of oil even if the car engine is turned off. This is possible courtesy

of what is called the anti-drainback valve. As the car engine slowly stops,

the anti-drainback valve retains a small amount of lubricating oil. Without

the engine running, the oil slowly drains back into the engine's bottom,

leaving the moving parts without the lubrication they need. The retained oil

is what lubricates them after the car engine is stopped.

In the early days of automobiles, they did not have any way of filtering the

oil in their engines. So, frequent oil changes were the order in their day

with some oil changes every 500 miles or even less. Oil filters did not come

to use until the 1920s. These cartridge-type oil filters were still crude and

consisted mostly of pleated filter paper encased in metal cylinders with many

holes. Imagine the environmental damages they could have caused in those days

as most of the oil went unfiltered.

In the 1950s, ensuring technological advances have produced the spin-on type

of oil filters. These made the oil to pass through them during engine runs.

These days, most oils are truly high-tech; some even promises that you have

to change them only after 15000 miles. Most spin-on oil filters employ a

pressure relief valve. If the oil filter becomes blocked, the pressure relief

valve allows the oil to pass through without filtering it.

There are various kinds of car oil filters available. However, any standard

oil filter will do as long as it is replaced within 3,000 miles (4,828 km).

As the job of the oil filter is to block large particles and prevent them

from damaging the engine, it is likely that after 3,000 miles the oil filter

may be getting clogged. Lastly, as long as the oil filter is equipped with

the aforementioned anti-drainback valve, your engine stands to get the proper

care and protection it deserves.

Nowadays, Volvo cars have gold performance oil filters. Using resin

impregnated glass filtration media which filters up particles down to the 1

micron level, Bosch oil filters have a long life. Its high performing, high

oil flow ensures that your engine will never run out of lubricating oil. It

can be easily put in place or removed via its 1-inch welded nut.

Why suffer with a dirty oil filter when you can have a clean one? These come

in cheap, by the way, so buy now!
