I've heard a few as below:

Don't keep it at constant revs - eg, cruising down the freeway on cruise control

Do vary loads on the engine - eg go up Greenmount hill in a few different gears to help bed in the rings

Don't rev out to red line nor keep it below say 2500rpm.

Work the engine in gradually over 1000kms then drop the oil and give it a good flush, full back up with recommended oil.

All, some or none of these may be correct. Just different things I've heard along the way.
