Engine Oil Change
WARNING: HOT OIL CAN CAUSE PERSONAL INJURY.
NOTE: Change engine oil and filter at intervals specified in the owner’s manual.
1. Operate the engine until the water temperature reaches 60°C (140°F). Shut the engine off.
2. Use a container that can hold at least 14 liters (15 quarts) to hold the used oil. Remove the oil drain plug and drain the used engine oil into the container.
3. Always check the condition of the used oil. This can give you an indication of engine problems that might exist.
● Thin, black oil indicates fuel dilution.
● Milky discoloration indicates coolant dilution.
4. Clean the area around the oil filter head. Remove the filter (Refer to Oil Filter Removal).
5. Install new oil filter (Refer to Oil Filter Installation).
6. Clean the drain plug and the sealing surface of the pan. Check the condition of the threads and sealing surface on the oil pan and drain plug.
7. Install the drain plug. Tighten the plug to 60 N·m (44 ft. lbs.) torque.
8. Use only High-Quality Multi-Viscosity lubricating oil in the Cummins Turbo Diesel engine. Choose the correct oil for the operating conditions. (Refer to Fluid types)
9. Fill the engine with the correct grade of new oil (11 quarts or 2¾ Gallons).
10. Start the engine and operate it at idle for several minutes. Check for leaks at the filter and drain plug.
11. Stop engine. Wait several minutes to allow the oil to drain back to the pan and check the level again.
USED ENGINE OIL DISPOSAL Care should be exercised when disposing of used engine oil after it has been drained from a vehicle’s engine.
Oil Filter Removal & Installation
Removal
1. Clean the area around the oil filter head. Remove the filter using a 90-95 mm filter wrench.
2. Clean the gasket surface of the filter head. The filter canister O-Ring seal can stick on the filter head. Make sure it is removed.
Installation
1. Fill the oil filter element with clean oil before installation. Use the same type oil that will be used in the engine.
2. Apply a light film of lubricating oil to the sealing surface before installing the filter.

Use an engine oil that is API Service Grade Certified. MOPAR provides engine oils that conform to this service grade.
SAE VISCOSITY
An SAE viscosity grade is used to specify the viscosity of engine oil. SAE 15W–40 specifies a multiple viscosity engine oil. When choosing an engine oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Select an engine oil that is best suited to your area’s particular ambient temperature range and variation. For diesel engines, refer to (Fig. 6)
