FACTS ABOUT ENGINE OIL

CONSUMPTION

Functions of engine oil

Engine oil has the primary function of lubricating and cooling

the inside of the engine, and plays a major role in maintaining

the engine in proper working order.

Engine oil consumption

It is normal that an engine should consume some engine

oil during normal engine operation. The causes of oil

consumption in a normal engine are as follows.

D

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 when the vehicle is decelerating sucks some of

this oil into the combustion chamber. This oil as well as

some part of the oil film left on the cylinder wall is burned by

the high temperature combustion gases during the

combustion process.

D

Oil is also used to lubricate the stems of the intake valves.

Some of this oil is sucked into the combustion chamber

together with the intake air and is burned along with the fuel.

High temperature exhaust gases also burn the oil used to

lubricate the exhaust valve stems.

The amount of engine oil consumed depends on the

viscosity of the oil, on the quality of the oil and on the way

the vehicle is driven.

More oil is consumed under driving conditions such as high

speeds and frequent acceleration and deceleration.
A new engine consumes more oil, since its pistons, piston rings

and cylinder walls have not become conditioned.

When judging the amount of oil consumption, note that

the oil may become diluted, making it difficult to judge the

true level accurately.

For example, if a vehicle is used for repeated short trips and

consumes a normal amount of oil, the dipstick may not show

any drop in the oil level at all, even after 600 miles (1000 km)

or more. This is because the oil is gradually becoming diluted

with fuel or moisture, making it appear that the oil level has not

changed.
The diluting ingredients evaporate out when the vehicle is then

driven at high speeds, as on an expressway, making it appear

that oil is excessively consumed after driving at high speeds.
