ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles (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. Wide-open throttle acceleration in low gear can be detrimental and should be
avoided.
The engine oil installed in the engine at the factory is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated climate conditions under which vehicle operations
will occur. For the recommended viscosity and quality grades, refer to “Maintaining Your Vehicle.”
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 an
engine problem or malfunction.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may result.
Engine Break-In Recommendation — SRT Version
A long break-in period is not required for the drivetrain (engine, transmission, and rear axle) in
your new vehicle.
Drive moderately during the first 500 miles (800 km). After the initial 60 miles (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 is a high performance synthetic lubricant, the 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 “Maintaining Your Vehicle”.
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.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or damage may result.
