Approved Fuel
This engine is designed to run on diesel fuel. Use only high quality fuel meeting ASTM D975 No. 2D,
EN590, or equivalent. At temperatures below 32° F (0° C) winter fuel blends are acceptable. See the
engine operation manual for more information.
Biodiesel blends up to 5% (B5) are approved for use in this unit. The fuel used must meet the
specifications for diesel fuel shown above. In certain markets, higher blends may be used if certain steps
are taken. Extra attention is needed when using biodiesel, especially when operating in cold weather or
storing fuel. Contact your Ditch Witch dealer or the engine manufacturer for more information.
Approved Coolant
This unit was filled with John Deere Cool-Gard coolant before shipment from factory. Add only John Deere
Cool-Gard (p/n 255-006) or any fully-formulated, ethylene glycol based, low-silicate, heavy-duty diesel

parts, filters, approved lubricants, TJC, and approved coolants to
maintain warranty.
• Use the “Service Record” on page 193 to record all required service to your machine.
IMPORTANT: Fuel sulfur content should be less than 5000 ppm (0.5%). Worldwide, fuel sulfur
regulations vary widely. Fuel used should always comply with local regulations. If using lube oil meeting
API CJ-4, (or other low SAPS equivalent) and fuel with sulfur content above 15 ppm (0.0015%), ULSD
in the U.S.), reduce oil change interval to 125 hours.
NOTICE:
• Use only pre-diluted or concentrated coolant mixed with distilled water. Do not use tap water.
• Do not use water or high-silicate automotive-type coolant. This will lead to engine damage or
premature engine failure.
• Do not mix heavy-duty diesel engine coolant and automotive-type coolant. This will lead to coolant
breakdown and engine damage.
