Lubrication And Maintenance - Mitsubishi 3000GT Service Manual

LUBRICATION AND
MAINTENANCE
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 ve-
hicle 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 fre-
quency 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
American 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".
Item numbers in the "SCHEDULED MAINTE-
NANCE TABLE" correspond to the item numbers
in the "MAINTENANCE SERVICE" section.
SEVERE SERVICE
Vehicles operating under severe service conditions
will require more frequent service.
Component service information is included in ap-
propriate units for vehicles operating under one
or more of the following conditions:
1. Trailer towing or police, taxi, or commercial 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 traf-
fic 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
Either of the following engine oils should be used:
(1) Engine oil displaying EOLCS certification mark
(2) Engine oil conforming to the API classification
SH ECII, SH/CD ECII, SG ECII or SGKD EC11
For further details, refer to "LUBRICANTS
SELECTION" section.
GENERAL
TSB Revision
Caution
Test results submitted to EPA have shown that
laboratory animals develop skin cancer after
prolonged contact with used engine oil. Accord-
ingly, the potential exists for humans to develop
a number of skin disorders, including cancer,
from such exposure to used engine oil. Care
should be taken, therefore, when changing en-
gine 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, thin-
ners, or solvents.
GEAR LUBRICANTS
The SAE grade number also indicates the viscosity
of Multi-Purpose Gear Lubricants.
The API classification system defines gear lubri-
cants in terms of usage. Typically gear lubricants
conforming to API GL-4 or GL-5 with a viscosity
of SAE 75W-85W or 75W-90 are recommended
for manual transaxle.
LUBRICANTS - GREASES 'i
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. d
FUEL USAGE STATEMENT
Your car must use unleaded gasoline only.
This car has a fuel tank filler tube especially de-
signed to accept only the smaller-diameter un-
leaded gasoline dispensing nozzle.
Caution
Using leaded gasoline in your car will damage
the catalytic converters and the oxygen sen-
sors. It is illegal, and will void warranty coverage
of the catalytic converters and the oxygen sen-
Your car is designed to operate on premium un-
leaded gasoline having a minimum octane rating
of 91 or 95 RON (Research Octane Number).
If premium unleaded gasoline is not available, un-
leaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used.
In this case, the performance and fuel consumption
will suffer a little degradation.
