An oil filter is an important part that protects your engine from
contaminants. Impurities from the oils in your engine, transmission and
hydraulic system can cause harm to your car, truck or SUV without a proper
oil filter.
Automobile oil filters must meet specific performance guidelines set by
the Society of Automotive Engineers. In general, oil filters follow a set of
universally accepted specifications that help prevent dirt, grime and oil
buildup from damaging your engine.
Oil Filter Canister
The oil filter sits in a canister or cartridge
housing the smaller parts that make up the filter---an important element
because it holds everything in place. Without the cartridge, the
individual pieces would fall out or come loose during the filtering
process for which it was designed. The canister contains a spring, media
filter, media end cap, anti-drain back seal, base plate with inlet hole
and base gasket. All these components combine to allow the oil filter to
work properly, removing harmful substances from the engine.
Other Filter Components
The media used in the oil filter is most important
individual piece, as its fibers act as a mesh screen that blocks
contaminant particles. The media screen allows oil to pass through while
blocking out the harmful junk. The anti-drain back seal is a necessary
part because it prevents leaks and oil draining back into the pan. The
base plate and gasket seal tightly to the canister to increase
durability and filter life. All these specifications ensure your vehicle
has protection against impurities that could ruin your engine. Changing
your oil and oil filter regularly increases engine life and vehicle
performance
