*See the SAE viscosities grades chart for correct temperature usage.
If you use oil and fluids that do not meet the defined specification and viscosity grade, this may lead to:
  • Component damage which is not covered by the vehicle warranty.
  • Longer engine cranking periods.
  • Increased emission levels.
  • Reduced engine performance.
  • Reduced fuel economy.
  • Degraded brake performance.
Note:   An engine block heater is recommended at temperatures below –10°F (–23°C).
Engine Oil Specifications
The use of correct oil viscosities for diesel engines is important for satisfactory operation. Determine which oil viscosity best suits the temperature range you expect to encounter for the next service interval from the following SAE viscosity grade chart.
Viscosity Grades
  • (1) For severe duty service, use SAE 5W-40 API CJ-4.
  • (2) For biodiesel fuel blends (B20 max), use SAE 5W-40 or SAE 15W-40 API CJ-4.
SAE Oil Label - 10W-30
The American Petroleum Institute (API) service symbol is used to identify the proper engine oil for your engine. The API service symbol will be displayed on the oil container you purchase. The API symbol displays the oil performance category in the top half of the symbol and the viscosity grade in the center of the symbol.
