GENERAL INFORMATION
NOOPA- -
Maintenance and lubncatron servrce recommenda-
tions have been compiled to provide maxrmum
protection for the vehicle owner's Investment
against all reasonable types of driving conditions,
Since these condjtrons vary with the individual
vehicle owner's drivrng habits, the area in which the
vehrcle is operated and the type of dnvrng to which
the vehicle is subjected, it IS necessary to prescribe
lubncatron and marntenance servtce 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
Informatron for service marntenance is provrded
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 rnformation is included in
appropriate unrts for vehicles operating under one or
more of the followrng conditions:
1. Trailer towrng or police, taxi, or commercral type
operatron
2. Operation of Vehicle
(1) Short-trip operation at freezing temperature
(engine not thoroughly warmed up)
(2) More than 500/0 operation in heavy city
traffic during hot weather above 32°C (90°F)
(3) ExtenGve 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, whrch is a single
grade oil. Engine oils are also identified by a dual
number, for example, SAE 1 OW-30, which indicates
3 tnultigrade 011.
The API classifrcatron system defines oil perform-
ance in terms of engine usage. Only engrne oil
designed "For Service SF" or "For Service SF/CC",
when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protectron. Both the SAE grade and the API
designation can be found on the container.
GEAR LUBRICANTS

MATERIALS ADDED TO FUEL
Indiscriminate use of fuel System cleaning agents-1 --
should be avoided. Many of these materials in-
tended for gum and varnish removal r@y contain
highly active solvents or srmrlar ingredrents that,_can-_Z __
be harmful to gasket and diaphragm materials used_-
in fuel system component parts.
