NOOPA-8
Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum protec-
tion for the vehicle owner’s investment against all rea-
sonable 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 sub-
jected, 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 American Petro-
leum 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”.
SEVERE SERVICE
Vehicles operating under severe service conditions will
require more frequent service.
Component service information is included in appropri-
‘.!ate units for vehicles operaing under one or more of
.!
the following conditions:
i’;? 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 traffic
,' during hot weather above 32°C (90°F)
:I- (3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
(7) Driving on-off-road

GEAR LUBWCANTS
The SAE grade number also indicates the viscosity of
Multi-Purpose Gear Lubricants.
The API classification system defines gear lubri-
cants in terrns of usage. Typically gear lubricants
conforming to API GL-4 or GL-5 with a viscosity of
SAE 8OW, SAE 90 are recommended for manual
transmission, front axle and rear axle (conventional
differential), and MITSUBISHI genuine gear oil Part
No. 8149630EX or equivalent, for rear axle (limited-
slip differential).
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 No. 2, should be used.
FUEL USAGE STATEMENT
Use gasolines having a minimum ant-knock index (Oc-
tane Value) of 87, (R + M)/2. This designation is com-
parable to a Research Octane Number of 91.
Unleaded gasolines only must be used in vehicles
equipped with catalyst emission control systems. All
vehicles, so equipped, have labels located on the in-
strument panel and on the back of fuel filler lid that
state, “UNLEADED GASOLINE ONLY”. These vehi-
cles also have fuel filler tubes especially designed to
accept the smaller diameter unleaded gasoline
dispensing nozzles only.
MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
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.
ENGINE OIL
The SAE grade number indicates the viscosity of en-
.’ gine oils, for example, SAE 30, which is a single grade
;,:g’ oil. Engine oils are also identified by a dual number, for
example, SAE lOW-30, which indicates a multigrade
oil.
The API classification system difines oil performance
in terms of engine usage. Only engine oil designed
“For Service SF” or “For Service SF/CC”, when avail-
able, should be used. These oils contain sufficient:
chemical additives to provide maximum engine protec-
tion. Both the SAE grade and the API designation can
be found on the container.
