ENGINE BREAK-IN RECOMMENDATIONS

For vehicles equipped with the 3.6L or 5.7L use the following engine break-in recom-
mendations:
A long break-in period is not required for the drivetrain (engine, transmission, clutch, and
rear axle) in your new vehicle.
Drive moderately during the first 300 mi (500 km). After the initial 60 mi (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the limits of local traffic laws
contributes to a good break-in. However, wide-open throttle acceleration in low gear can
be detrimental and should be avoided.
The engine oil, transmission fluid, and axle lubricant installed at the factory is high-quality
and energy-conserving. Oil, fluid, and lubricant changes should be consistent with
anticipated climate and conditions under which vehicle operations will occur. For the
recommended viscosity and quality grades, refer to "Maintenance Procedures" in "Main-
taining Your Vehicle".
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may
result.
NOTE:
A new engine may consume some oil during its first few thousand miles (kilometers) of
operation. This should be considered a normal part of the break-in and not interpreted as
an indication of difficulty. Please check your oil level with the engine oil indicator often
during the break in period. Add oil as required.
For vehicles equipped with the 6.4L use the following engine break-in recommendations:
Despite modern technology and World Class manufacturing methods, the moving parts of
the vehicle must still wear in with each other. This wearing in occurs mainly during the first
500 miles (805 km) and continues through the first oil change interval.
It is recommended for the operator to observe the following driving behaviors during the
new vehicle break-in period:
0 to 100 miles (0 to 161 km):
• Do not allow the engine to operate at idle for an extended period of time.
• Depress the accelerator pedal slowly and not more than halfway to avoid rapid
acceleration.
• Avoid aggressive braking.
• Drive with the engine speed less than 3,500 RPM.
• Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.
