o The engine oil consumption is
strongly effected by the viscosity
and quality of oil, engine rpm and
driving condition etc.
More engine oil may be consumed
under severe driving conditions
such as high speeds, frequent
acceleration and deceleration,
compared to normal driving.

ENGINE OIL CONSUMPTION
Function of engine oil
Engine oil has the primary function of
lubricating and cooling the inside of
the engine.
Engine oil consumption
It is normal that an engine should
consume some engine oil in the course
of normal driving. The cause of oil
consumption in a normal engine are as
follows;
o Engine oil is used to lubricate pis-
tons, 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 dur-
ing engine operation sucks some
of the oil into the combustion cham-
ber.
This oil with some oil of the cylin-
der wall is burned by the high tem-
perature combustion gases during
the combustion process.

WARNING:
Be very careful not to touch the
radiator hose when adding the en-
gine oil as it may be hot enough to
burn you.
