You will find numerous opinions on that subject.
For mine, I drive them easy up and down through the rpm range for the first 500 miles and let them go through several heating and cooling cycles.
Then I change the oil and observe how much metal is in the oil and on the magnetic oil pan plugs I always use. If it does not appear excessive (It usually won't) I complete the oil change and drive it like I intend to after that. I will change the oil again and make the same observations at 1000 and 3000 miles, then just change it at regular 3-5000 mile intervals depending on how dirty the oil appears when I check it. I don't stick to any certain mileage for my oil changes because if I do a lot of short trips the oil will get dirty and contaminated faster than if I do long trips. So I go by how dirty the oil looks when I check the level. If it is coal, tar black, it gets changed.
