How does an oil filter work? Have you ever watched someone make a sandbox in a playground? When it comes time to put the sand in, they use a sieve to sift the sand. The sieve is a metal grate or screen with very tiny holes to let the sand pass through, but it will catch rocks, glass or any other large object that should not be found in child’s sandbox. As objects fill up the holes in the sieve, the sand particles that can slip through get smaller in size causing some larger sand particles to also get trapped in the sieve. If the sieve gets clogged, it won’t let any sand pass through, and it will then need to be emptied.

To the left is a picture of how a spin on oil filter operates. The contaminants in an engine are caught by the oil and carried to the oil filter. The function of the oil filter is to efficiently remove and retain those contaminants so that they cannot work their way into other, sensitive engine parts which can be ruined by even tiny amounts of dirt. The oil filter must do this job without offering too much resistance to the flow of oil through the engine.

The spin on oil filter is composed of a housing (that looks like a metal can), and a filter cartridge. The filtering material in this cartridge can hold a remarkable amount of dirt and sludge, but at some point it loses its ability to trap any more dirt. As with the motor oil, the oil filter becomes less effective and fills up with trapped contaminants sooner, as the stress put upon the engine increases.

It would be disastrous if a plugged oil filter blocked the oil from reaching the engine. The damage would be immediate and devastating. Instead, when an oil filter becomes fully clogged with contaminants, the oil is forced through a bypass relief valve, around the filter element and back into the engine unfiltered. Obviously, this is better than having the engine blow up, but it is also not good to have unfiltered oil circulating through the engine. An oil filter begins to clog after approximately 4,500 to 5,500 miles of use, or sooner if the system was particularly dirty prior to installation. It is there fore wise to change the oil filter often enough that the relief valve never has a chance to open.
