Jeep 2012 Grand Cherokee SRT - User Guide - Manual (Page 29)

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 difficulty.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in the engine or
damage may result.
ENGINE BREAK-IN RECOMMENDATIONS — SRT8 VERSIONS
• 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 mi (800 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 “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
