'What's The Best Way To Break-In A New Engine ??
The Short Answer: Run it Hard !
Several factors make the older information on break-in obsolete.
Nowadays, the piston ring seal is really what the break in process is all about. Contrary to popular belief, piston rings don't seal the combustion pressure by spring tension. Ring tension is necessary only to "scrape" the oil to prevent it from entering the combustion chamber. So, how do the rings seal against the tremendous combustion pressure ??
From the actual gas pressure itself !!
There's a very small window of opportunity to get the rings to seal really well ... the first 20 miles !! '
This must be why Lamborghini's factory test drivers run the crap out of each car before it's final inspection.
