Motor oil is essentially the
lifeblood of any
car. The role of engine oil is to
keep the
moving parts of the engine lubricated, to
protect them against rust corrosion, and
with modern detergent oil additives to
keep them free of sludge and general
engine gunk.
The purpose of the Oil Filter is to keep the
oil clean.
Oil is pumped
through the filter and then
distributed
throughout the engine. The filter traps
debris and particles that
would damage the
engine.
