Approved Fuel
The engine is this unit 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
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. 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
engine coolant meeting ASTM specification D5345 (prediluted) or D4985 (concentrate) and containing
supplemental coolant additives (SCAs) meeting John Deere specification JDM H24A2.
Engine Oil Temperature Chart
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 fuel with sulfur
content above 5000 ppm (0.05%, low sulfur diesel in the U.S.), reduce oil change interval by half.
NOTICE: Do not use water or high-silicate automotive-type coolant. This will lead to engine damage or
premature engine failure.
NOTICE: Do not mix heavy-duty diesel engine coolant and automotive-type coolant. This will lead
coolant breakdown and engine damage.
