Following recommendations are the first choice oil weights shown in the Detroit Diesel Fuel Pincher Manual for the engines listed. The temperature range for these recommendations is -32°C (-25°F) upwards. For extreme cold, that is at temperatures below the range listed here, the oil recommendation probably changes.
Consult your oil supplier for further advice.
OIL: For Detroit Diesel 2-Stroke Engines
