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 40 minimum. Cetane number greater
than 47 is preferred, especially for temperatures below
–20 °C (–4 °F) or elevations above 1675 m (5500 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
0.52 mm as measured by ASTM D6079 or ISO 12156-1.
A maximum scar diameter of 0.45 mm is preferred.
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).
Sulfur content for Interim Tier 4, Final Tier 4,
Stage III B, and Stage IV 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—2000 mg/kg
(1000—2000 ppm) REDUCES the oil and filter change
interval.
•
BEFORE using diesel fuel with sulfur content greater
than 2000 mg/kg (2000 ppm), contact your John Deere
dealer.
Sulfur Content for Tier 2 and Stage II Engines
•
Use of diesel fuel with sulfur content less than 2000
mg/kg (2000 ppm) is RECOMMENDED.
•
Use of diesel fuel with sulfur content 2000—5000 mg/kg
(2000—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 John Deere
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
interval.
IMPORTANT: Do not mix used diesel engine oil or any
other type of lubricating oil with diesel fuel.
Improper fuel additive usage may cause damage
on fuel injection equipment of diesel engines.
Supplemental Diesel Fuel Additives
Diesel fuel can be the source of performance or other
operational problems for many reasons. Some causes
include poor lubricity, contaminants, low cetane number,
and a variety of properties that cause fuel system
deposits. These and others are referenced in other
sections of this Operator's Manual.
To optimize engine performance and reliability, closely
follow recommendations on fuel quality, storage, and
handling, which are found elsewhere in this Operator's
Manual.
To further aid in maintaining performance and reliability of
the engine's fuel system, John Deere has developed a
family of fuel additive products for most global markets.
The primary products include Fuel-Protect Diesel Fuel
Conditioner (full feature conditioner in winter and summer
formulas) and Fuel-Protect Keep Clean (fuel injector
deposit removal and prevention). Availability of these and
other products varies by market. See your local John
Deere dealer for availability and additional information
about fuel additives that might be right for your needs.
