LUBRICATION AND MAINTENANCEM1001001200336
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum pro-
tection for the vehicle owner's investment against all
reasonable types of driving conditions. Since these
conditions vary with the individual vehicle owner's
driving habits, the area in which the vehicle is oper-
ated and the type of driving to which the vehicle is
subjected, it is necessary to prescribe lubrication and
maintenance service on a time frequency as well as
mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by the
Society of Automotive Engineers (SAE) and the Aus-
tralian Petroleum Institute (API).
MAINTENANCE SCHEDULES
For Information on service maintenance refer to the
"Service handbook".
ENGINE OIL
Tests have shown that laboratory animals
develop skin cancer after prolonged contact with
used engine oil. Accordingly, the potential exists
for humans to develop a number of skin disor-
ders, including cancer, from such exposure to
used engine oil. Therefore, when changing
engine oil, be careful not to touch it as much as
possible. Protective clothing and gloves, that
cannot be penetrated by oil, should be worn. The
skin should be thoroughly washed with soap and
water, or use waterless hand cleaner, to remove
any used engine oil. Do not use petrol, thinners,
or solvents.Either of the following engine oils should be used:
1. Engine oil conforming to the ACEA classification:
"For service A1, A2 or A3.
2. Engine oil conforming to the API classification:
"For service SG" or higher.
FUEL USAGE STATEMENT
Using leaded petrol in this car will damage the
catalytic converters and heated oxygen sensors,
and affect the warranty coverage validity.
This vehicle must use unleaded petrol only.
This vehicle has a fuel filler tube which is especially
designed to accept only the smaller-diameter
unleaded petrol dispensing nozzle.
The 3.8L model is designed to operate on unleaded
petrol having an octane rating (DIN 51607) of 90
RON or higher.
.
PETROL CONTAINING ALCOHOL
Some petrol sold at service stations contain alcohol
although they may not be so identified.
Using fuels containing alcohol is not recommended
unless the nature of the blend can be determined as
being satisfactory, as follows.
Gasohol: A mixture of 10% ethanol and 90%
unleaded gasoline may be used in your vehicle. If
driveability problems are experienced as a result of
using gasohol, it is recommended that the vehicle be
operated on petrol.
Methanol: Do not use petrol containing methanol
(wood alcohol). Using this type of alcohol can result
in vehicle performance deterioration and damage
critical parts in the fuel system components. Fuel
system damage and performance problems resulting
from the use of petrol containing methanol may not
be covered by the new vehicle warranty.
MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents
should be avoided. Many materials intended for gum
and varnish removal may contain highly active sol-
vents or similar ingredients that can be harmful to
gasket and diaphragm materials used in fuel system
component parts.

CATALYTIC CONVERTER
GENERAL DESCRIPTION (CATALYTIC CONVERTER)M1173005300131
The three way catalytic converter, together with the
closed loop air-fuel ratio control based on the oxygen
sensor signal, oxidizes carbon monoxides (CO) and
hydrocarbons (HC), also reduces nitrogen oxides
(NOx). When the mixture is controlled at stoichiometric
air-fuel ratio, the three way catalytic converter pro-
vides the highest purification against the three con-
stituents, namely, CO, HC and NOx.
