DO-IT-YOURSELF MAINTENANCE
8
The engine oil and filter should be
changed at those intervals specified in
the maintenance schedule in Section 5.
If the car is being driven in severe
conditions, more frequent oil and filter
changes are required.
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 selec-
tor lever in reverse gear.
2. Lift up the front passenger's seat
(Refer to "To Inspect the Engine
Compartment Under the Front
Passenger's Seat" on page 1-13.)
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.
CHANGING THE OIL AND
FILTER
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 down-
wards 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 tempera-
ture 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.
