Lubrication And Maintenance; Server Service; Engine Oil - Mitsubishi 1989-1993 GALANT Service Manual

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
M A I N T E N A N C E T A B L E " c o r r e s p o n d t o t h e
"MAINTENANCE SERVICE" section numbers.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service.
Component service information

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",
GENERAL
is Included i n
TSB Revision
when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protection. Both the SAE grade and the
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
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 premium
unleaded gasoline having a minimum octane rating
of 91 or 95 RON (Research Octane Number).
