CHANGING THE OIL AND FIL-
TER
The procedure for changing the oil
and filter is as follows:
1. Park the car on level ground and
set the parking brake. Start the
engine and let it warm up until the
needle on the coolant temperature
gauge moves above the lowest
mark. Turn the engine off and place
the gear selector lever in "P" (auto-
matic) or reverse gear (manual
transaxle). Set the parking brake.
2. Open the hood and remove the
engine oil filler cap.
3. Slide underneath the car and loosen
the drain plug by turning it counter-
clockwise with a wrench of the
proper size. Be sure that a drain
pan is in position to catch the oil as
it drains out, then remove the drain
plug.
WARNING:
Be very careful when draining the
engine oil as it may be hot enough
to burn you!
The engine oil and filter should be
changed at those intervals specified
in the maintenance schedule in Sec-
tion 5. If the car is being driven in
severe conditions, more frequent oil
and filter changes are required.

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 while nor-
mal driving. The cause of oil con-
sumption 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.
o The engine oil consumption is
strongly effected 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 driv-
ing condition.
