Engine Break in

[warmbyj]

Just got a call from the Dealer and the wait for my 392 is almost over. What is the recommendation for engine break in? Are we supposed to beat on it like it owes us money, or teat it to champagne and caviar for some amount of miles?

See below from owners manual from another forum. Hope this helps.

From the OM:
Engine break in occurs mainly during the first 500 miles (805 km) and continues through the first oil change interval.
It is recommended for the operator to observe the following driving behaviors during the new vehicle break-in period:
0 to 100 miles (0 to 161 km):

•  Do not allow the engine to operate at idle for an extended period of time.
•  Press the accelerator pedal slowly and not more than halfway to avoid rapid acceleration.
•  Avoid aggressive braking.
•  Drive with the engine speed below
  3,500 RPM.
•  Maintain vehicle speed below 55 mph (88 km/h) and observe local speed limits.

100 to 300 miles (161 to 483 km):
 Press the accelerator pedal slowly and not more than halfway to avoid rapid accelera- tion in lower gears (FIRST to THIRD gears).
 Avoid aggressive braking.
 Drive with the engine speed below
5,000 RPM.
 Maintain vehicle speed below 70 mph (112 km/h) and observe local speed limits.
300 to 500 miles (483 to 805 km):

•  Exercise the full engine RPM range, shifting manually (paddles or gear shift) at higher RPM when possible.
•  Do not perform sustained operation with the accelerator pedal at wide open throttle.
•  Maintain vehicle speed below 85 mph (136 km/h) and observe local speed limits.
  For the first 1,500 miles (2,414 km):
   Avoid high engine and driveline loading.

NOTE:
Check engine oil with every refueling and add if necessary. Oil and fuel consumption may be higher through the first oil change interval. Running the engine with an oil level below the add mark can cause severe engine damage.
