Lubrication; Diesel Fuel; Required Fuel Properties - Northern Lights M50C13 Operator's Manual

USE CORRECT FUELS, LUBRICANTS AND
COOLANT
IMPORTANT: Use only fuels, lubricants and coolants that
meet specifications outlined in this manual.
Consult your Northern Lights servicing dealer for
recommended fuels, lubricants, and coolant. Also
available are necessary additives for use when operating
engines in tropical arctic, or any other adverse conditions.

DIESEL FUEL

Consult your local fuel distributor for properties of the
diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low
temperature requirements of the geographical area in
which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are
recommended. Renewable diesel fuel produced by
hydrotreating animal fats and vegetable oils is basically
identical to petroleum diesel fuel. Renewable diesel that
meets EN 590 or ASTM D975 is acceptable for use at all
percentage mixture levels.

REQUIRED FUEL PROPERTIES

In all cases, the fuel shall meet the following properties:
Cetane number of 43 minimum. Cetane number greater
than 47 is preferred, especially for temperatures below
–20°C (–4°F) or elevations above 1500 m (5000 ft.).
Cold Filter Plugging Point (CFPP) should be at least
5°C
(9°F) below the expected lowest temperature or Cloud
Point below the expected lowest ambient temperature.
Fuel lubricity should pass a maximum scar diameter of
0.45 mm as measured by ASTM D6079 or ISO 12156-1.
Diesel fuel quality and sulfur content must comply with
all existing emissions regulations for the area in which
the engine operates. DO NOT use diesel fuel with sulfur
content greater than 10 000 mg/kg (10 000 ppm).

Lubrication

Sulfur content for Interim Tier 4 and Stage III B
engines
• Use ONLY ultra low sulfur diesel (ULSD) fuel with a
maximum of 15 mg/kg (15 ppm) sulfur content.
Sulfur Content for Tier 3 and Stage III A Engines
• Use of diesel fuel with sulfur content less than 1000
mg/kg (1000 ppm) is RECOMMENDED
• Use of diesel fuel with sulfur content 1000–5000 mg/kg
(1000–5000 ppm) REDUCES oil and filter change
intervals.
• BEFORE using diesel fuel with sulfur content greater
than 5000 mg/kg (5000 ppm), contact your Northern
Lights dealer
Sulfur Content for Tier 2 and Stage II Engines
• Use of diesel fuel with sulfur content less than 500
mg/kg (500 ppm) is RECOMMENDED.
• Use of diesel fuel with sulfur content 500–5000 mg/kg
(500–5000 ppm) REDUCES the oil and filter change
interval
• BEFORE using diesel fuel with sulfur content greater
than 5000 mg/kg (5000 ppm), contact your Northern
Lights dealer
Sulfur Content for Other Engines
• Use of diesel fuel with sulfur content less than 5000
mg/kg (5000 ppm) is recommended.
• Use of diesel fuel with sulfur content greater than 5000
mg/kg (5000 ppm) REDUCES the oil and filter change
intervals.
IMPORTANT: Do not mix used diesel engine oil or any
other type of lubricating oil with diesel fuel.
IMPORTANT: Improper fuel additive usage may
cause damage on fuel injection equipment of diesel
engines.
