DIESEL ENGINE BREAK-IN RECOMMENDATIONS
The 3.0 turbocharged diesel engine does not require a break-in period due to its
construction. Normal operation is allowed, providing the following recommendations
are followed:
• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant
weight.
NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
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. The recommended viscosity and quality grades are
shown under “FLUIDS, LUBRICANTS AND GENUINE PARTS”, under “MAINTAINING
YOUR VEHICLE”. NON-DETERGENT OR STRAIGHT MINERAL OILS MUST NEVER BE
USED.
