1 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 could lead to:
• Component damage that your vehicle
warranty does not cover.
• Longer engine cranking periods.
• Increased emission levels.
• Reduced engine performance.
• Reduced fuel economy.
• Reduced brake performance.
Note: We recommend an engine block
heater 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.
