Vary your speed so the car has a chance to break in at all speeds.
Is this the correct procedure?
Yes, you will want to vary your speed as a part of the breaking in process. Also, take care to not overly labor the engine and avoid speeding excessively. You can read more about your vehicle and breaking in advice in your Owner's Manual, available for download here: https://owner.ford.com/servlet/Conte...vehicleIndex=0
If you have any additional questions, feel free to send a PM my way.
Congrats on the ST; I'm sure you'll love it!
