Engine oil has the primary function of lubricat-
ing and cooling the inside of the engine.

Engine oil consumption Engine oil consumption
It is normal that an engine should consume
some engine oil while normal driving. The cause
of oil consumption in a normal engine are as
follows;
o Engine oil is used to lubricate pistons, piston
rings and cylinders.
A thin film of oil is left on the cylinder wall
when a piston moves downwards in the
cylinder. High negative pressure generated
during engine operation sucks some of the
oil into the combustion chamber.
This oil with some oil of the cylinder wall is
burned by the high temperature combustion
gases during the combustion process.
o The engine oil consumption is strongly ef-
fected by the viscosity and quality of oil,
engine rpm and driving condition etc. The
engine oil is more consumed under severe
driving conditions such as high speeds and
frequent acceleration and deceleration than
normal driving condition.
