LUBRICATION RECOMMENDATIONS
Motor
oils
used
for
internal-combustion
engine
lubrication perform many useful functions including:
dissipating heat, sealing piston rings, preventing metal
to-metal contact wear, and reducing power loss through
friction.
The lubricating oil recommendation is based upon
engine design, type of service, and the atmospheric
temperature prevailing. High quality oils are required to
ensure maximum performance, long engine life, and
minimum cost of operation.
Continental industrial diesel engines operate in a wide
range of service conditions and seasonal temperatures,
so our recommendations are given for various types of
service and ambient temperatures.
API SERVICE DESIGNATIONS
We recommend using oil described below for all
continental industrial diesel applications.
CD - Service Class D
Service typical of industrial diesel engines operating
under engine manufacturer’s warranties. High detergent
exceeds engine manufacturer warranty requirements.
SE/CD...............Oil Classifications may be used.
SFICD...............Oil Classifications may be used.
SG ....................Oil Classifications may be used.
SAE OIL BODY GRADES
The oil grades available from the lightest (SAE 5W) to
the heaviest (SAE 50) are:
Multi-grade oils such as SAE 5W-20 and SAE 15W-50
have the starting grade characteristics of the lighter oils
and, after warm-up, have the running characteristics of
the heavier grade.
The following SAE grades are general recommendations
for Continental industrial diesel engines during changing
seasonal atmospheric temperatures:
Sump Oil Temperature
SAE Grade
210-250°
40
(99-121 °C)
30
160-210° F)
10W-30, 10W-40
(71-99° C)
20W-40, 15W-40
20W-50, 15W-50
130-160°F
20
(55-71°C)
10W-30, 10W-40
The Multi-grade oil used should cover the single grade
recommendation
for
the
atmospheric
temperature
involved, e.g. SAE 10W-30 covers SAE-10W, SAE-
20W, SAE 20, and SAE 30.

NOTE
1.
Lube oil and filter must always be
changed after the first 50 hours of
operation of a now or rebuilt engine.
2.
Environmental, Installation, fuel system,
and general engine conditions can all
Influence lubricant performance. Lube
oil analysis programs are recommended
In all applications for optimum engine
performance and life.
Standard Continental supplied starters and alternators
have sealed bearings requiring no lubrication. Check
your specification for accessories which may require
periodic lubrication.
