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 “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 normal 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.

That said, I just hitched up the boat and drove across country for mine.

Here's mine....

I put about 150 miles on mine around town then took off for Michigan. A little over 1200 miles straight through. Used cruise off and on. Ran between the speed limit and 8 over for 19 hours with just short travel breaks for me and my dog and 2 gas stops. Trucks running just fine..... Now I have about 5000 miles that includes a 2nd trip back to Florida. This one was a relaxed 2 day'r because I had my wife and mother in law in the truck along with the dog.

Not long to initially break in around 300 miles. But the entire seating of the motor and transmission is most likely around the 5000 marker.

Burnout till your tires catch fire.
