00-34GENERAL- Lubrication and Maintenance
LUBRICATION AND
MAINTE-
NANCEMOOPA-
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum protection 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 operated 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), the Amer-
ican Petroleum Institute (API) and the National
Lubricating Grease Institute (NLGI).
MAINTENANCE SCHEDULES Information for service maintenance is provided
under “SCHEDULED MAINTENANCE TABLE”.
Three schedules are provided; one for “Required Maintenance”, one for “General Maintenance” and
one for “Severe Usage Service”.
The item numbers used in the “SCHEDULED MAINTENANCE TABLE” correspond to th
e
“MAINTENANCE SERVICE” section numbers.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service. Component service information
isIncluded i
n
appropriate units for vehicles operating under one or
more of the following conditrons:
1.Trailer towing or police, taxi, or
commerciai
type
operation
2. Operation of Vehicle (1) Short-trip operation at freezing temperature(engine not thoroughly warmed up)
(2) More than 50% operation in heavy city traffic during hot weather above
32°C (90°F)
(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
The SAE grade number indicates the viscosity of engine oils, for example, SAE 30, which is a single
grade oil. Engine oils are also identified by a dual number, for example, SAE 1
OW-30, which Indicates
a multigrade oil.
The API classification system defines oil perform- ance in terms of engine usage. Only engine oil
designed “For Service SG” or “For Service
SGKD”,
when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protection. Both the SAE grade and the API
designation can be found on the container.
Caution
Test results submitted to EPA have shown that
laboratory animals develop skin cancer after
prolonged contact with used engine oil. Accor-
dingly, the potential exists for humans to de-
velop a number of skin disorders, including
cancer, from such exposure to used engine oil.
Care should be taken, therefore, when changing engine oil, to minimize the amount and length of
exposure time to used engine oil on your skin.
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 gasoline,
thinners, or solvents.
GEAR LUBRICANTS
The SAE grade number also indicates the viscosity of Multi-Purpose Gear Lubricants.
The API classfication
system defines gear lubricants
in terms of usage. Typically gear lubricants conform-
ing to API
GL-4 or GL-5 with a viscosity of SAE 75W-85W
are recommended for manual transaxle.
LUBRICANTS
- GREASES
Semi-solid lubricants, bear the
NLGI designation and
are further classified as grades 0, 1, 2, 3 etc.
Whenever “Chassis Lubricant” is specified,
Multi-
Purpose Grease, NLGI grade 2 should be used.
FUEL USAGE STATEMENT
Your vehicle must use unleaded gasoline only.
This vehicle has a fuel filler tube especially designed
to accept only the smaller-diameter unleaded gaso- line
dispensrng nozzle.
Caution
Using leaded gasoline in your vehicle will damage
the catalytic converter, and affect the warranty
coverage validity.
All vehicles except those with DOHC engines
Your vehicle is designed to operate on unleaded
gasoline having a minimum octane rating of 87 or
91 RON (Research Octane Number).
Vehicles equipped with DOHC engines
Your vehicle is designed to operate on premiumunleaded gasoline having a minimum
octane rating
of 91 or 95 RON (Research Octane Number).
TSB Revision

GENERAL -Lubrication and Maintenance/Recommended Lubricants and Lubricant Capacities Table00-35
If premium unleaded gasoltne IS not available,
MATERIALS ADDED TO FUEL
unleaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used. Indiscriminate use of fuel system cleaning agents
In this case, the performance and fuel consumption should be avoided. Many of these materials
in-
WIII suffer a little degradatron.tended for gum and varnish removal may contain
highly active
solvents or similar ingredients that can
be harmful to gasket and diaphragm materials used
in fuel system component parts.
Gasolines containing alcohol
Some gasolrnes sold at service stations contain
alcohol, although they may not be SC identified. Use
of fuels containing alcohol is not recommended
unless the nature of the blend can be
determrned
as being satisfactory.
Gasohol
- A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used
In your
car. If
driveability problems are experienced as a
result of using gasohol, it IS recommended that the
car be operated on gasoline. Methanol
- Do not use gasolines containing
methanol (wood alcohol). Use of this type of
alcohol can result in vehicle performance deteriora-
tion and damage critical parts in the fuel system
components. Fuel system damage and performance
problems, resulting from the use of gasolines
containing methanol, may not be covered by the
new car warranty.
Gasolines containing MTBE (Methyl Tertiary Butyl
Ether)
Unleaded gasolrne containrng
15% or less MTBE
may be used in your car. (Fuel containing MTBE
over 15% vol. may cause reduced engine per-
formance and produce vapor lock or hard starting.) RECOMMENDED

ENGINE OIL
Engine oil should be used which conform to the requirements
of the API classification “For Service SG” or “For Service
SGKD”, and have the proper SAE grade number for the
expected temperature range.
Caution
Nondetergent or straight mineral oil must never be used.
Energy Conserving Oil
In order to improve fuel economy and conserve energy new,
lower friction engine oils have been developed. These oils are readily available and can be identified by such labels as “Energy
Conserving”, “Energy Saving”,
“Improved Fuel Economy”,
etc.

A standard
.symbol appears on the top of oil containers and has
three district areas for identifying various aspects of the oil.
The top
polqion will indicate the quality of the oil. The center
portion will show the SAE viscosity grade, such as SAE lOW-30.
“Energy Conserving” shown in the lower portion,
indicates that the oil has fuel-saving capabilities.

Example:
The safe operating temperature is - 15°C (5°F) when the measured specific gravity is 1.058 at the Coolant
temperature of 20°C (68°F).
Cautions
1. If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reas\
ons, be sure to maintain the
concentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.
