RE: Noobish engine question
Here's what the challenger's manual says. You should be ok to drive from one state to the other if you drive around 60 mi before hand. I'm sure that will happen naturally. Fully warm your engine up too ( they dont mention it )
ENGINE BREAK-IN RECOMMENDATIONS
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 energyconserving.
Oil, fluid, and lubricant changes should be
consistent with anticipated climate and conditions under
which vehicle operations will occur. The recommended
viscosity and quality grades is shown in Section 7.
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 as a normal part of the break-in and
not interpreted as an indication of difficulty.
