ENGINE BREAK-IN
RECOMMENDATIONS — GASOLINE
ENGINE
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 contrib-
utes 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 consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. For
the recommended viscosity and quality
grades, refer to “Fluids And Lubricants” in
“Technical Specifications”.
CAUTION!
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 nor-
mal part of the break-in and not interpreted
as a problem. Please check your oil level with
the engine oil indicator often during the
break in period. Add oil as required.

ENGINE BREAK-IN
RECOMMENDATIONS — 3.0L DIESEL
The diesel engine does not require a break-in
period due to its construction. Normal opera-
tion is allowed, providing the following rec-
ommendations are followed:
• Warm up the engine before placing it underload.
• Do not operate the engine at idle for pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and tempera- ture 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 consis-
tent with anticipated climate conditions un-
der which vehicle operations will occur. The
recommended viscosity and quality grades
are shown under “Fluids And Lubricants” in
"Technical Specifications” in this manual.
NON-DETERGENT OR STRAIGHT MINERAL
OILS MUST NEVER BE USED.
ENGINE BREAK-IN
RECOMMENDATIONS — 6.7L DIESEL
The Cummins 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 pro- longed periods.
• Use the appropriate transmission gear to prevent engine lugging. • Observe vehicle oil pressure and tempera-
ture 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.
For additional vehicle break-in requirements,
refer to “Trailer Towing” in “Starting And
Operating” of the Owner’s Manual.
Because of the construction of the Cummins
turbocharged diesel engine, engine run-in is
enhanced by loaded operating conditions
which allow the engine parts to achieve final
finish and fit during the first 6,000 miles
(10 000 km).STARTING AND OPERATING
