Oil And Filter Service Intervals; Lubricant Storage; Oil Filters - Northern Lights M50C13 Operator's Manual

Mixing of Lubricants
In general, avoid mixing different brands or types of oil.
Oil manufacturers blend additives in their oils to meet
certain specifications and performance requirements.
Mixing different oils can interfere with the proper
functioning of these additives and degrade lubricant
performance.
Alternative and Synthetic Lubricants
Conditions in certain geographical areas may require
lubricant recommendations different from those printed in
this manual. Some Northern Lights brand coolants and
lubricants may not be available in your location. Consult
your Northern Lights dealer to obtain information and
recommendations. Synthetic lubricants may be used if
they meet the performance requirements as shown in this
manual.
The temperature limits and service intervals shown in
this manual apply to both conventional and synthetic
lubricants.
Re-refined base stock products may be used if the finished
lubricant meets the performance requirements.
DIESEL ENGINE OIL AND FILTER SERVICE
INTERVALS
The oil and filter service intervals in the maintenance
schedule (page 27) should be used as a reference.
Actual service intervals also depend on operation and
maintenance practices. It is suggested to use oil analysis
to determine the actual useful life of the oil and to aid in
selection of the proper oil and filter service interval.
Oil and filter service intervals are based on a combination
of oil pan capacity, type of engine oil and filter used, and
sulfur content of the diesel fuel.
NOTE: The service interval of "Other Oils" may be
extended only if oil analysis is performed to determine
the actual service life, to a maximum not to exceed that of
Plus-50.
Diesel fuel sulfur level will affect engine oil and filter
service intervals. Higher fuel sulfur levels reduce oil and
filter service intervals as shown in the table.
• Use of diesel fuel with sulfur content less than 0.05%
(500 mg/kg) is strongly recommended.
Lubrication
• Use of diesel fuel with sulfur content 0.05%
(500 mg/kg) to 0.50% (5000 mg/kg) may result in
REDUCED oil and filter change intervals as shown in
the table.
• BEFORE using diesel fuel with sulfur content greater
than 0.50% (5000 mg/kg), contact your Northern Lights
dealer.
IMPORTANT: When using biodiesel blends greater than
B20, reduce the oil and filter service interval by 50% or
monitor engine oil based on test results from Oilscan.
Oil types in the table include:
• Northern Lights Plus-50 II and John Deere Plus-oils.
• Other oils" include Torq-Gard Supreemen
API CJ-4, API CK-4, API CI-4, ACEA E9, ACEA E7,
ACEA E6 or ACEA E5

LUBRICANT STORAGE

Your equipment can operate at top efficiency only when
clean lubricants are used. Use clean containers to handle
all lubricants.
Store lubricants and containers in an area protected from
dust, moisture, and other contamination. Store containers
on their side to avoid water and dirt accumulation.
Make certain that all containers are properly marked to
identify their contents. Properly dispose of all old
containers and any residual lubricant they may contain.

OIL FILTERS

Filtration of oils is critically important for proper
operation and lubrication. Northern Lights brand oil
filters have been designed and produced specifically for
Northern Lights applications.
Northern Lights filters adhere to engineering
specifications for quality of the filter media, filter
efficiency rating, strength of the bond between the filter
media and the element end cap, fatigue life of the canister
(if applicable), and pressure capability of the filter seal.
Non-Northern Lights branded oil filters might not meet
these key specifications.
Always change oil filters regularly as specified in this
manual.
