Jeep Wrangler: STARTING AND OPERATING / ENGINE BREAK-IN RECOMMENDATIONS — DIESEL ENGINE (IF EQUIPPED)
The 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. For recommended
viscosity and quality grades.
NON-DETERGENT OR STRAIGHT MINERAL OILS
MUST NEVER BE USED.
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)...
Before exiting the vehicle, make sure that the
parking brake is fully applied. Also, be certain to
leave an automatic transmission in PARK, or
manual transmission in REVERSE or FIRST
gear...
