The S3 is scheduled to arrive in approximately two weeks so I was just wondering if someone could once and for all clear up all the mis-information you see about how to "run-in" a new engine? I've read such things as: - Taking it easy and applying a gentle run-in - no jackrabbit starts or stops, no redlining, no cruising at a constant speed for hundreds of miles, etc. - Running it relatively hard in order for the piston rings and bearings to 'seat' properly. - Not using synthetic oils within the run-in period. - Changing the oil after the first 100 miles. - Does the 'run-in' period still even exist with the way today's modern engines are manufactured? - Vary engine RPMâs for the first 500 miles, using both hard/mild acceleration and engine braking. - "Running at uber high RPMâs on a brand new engine does absolutely nothing for an engines performance and longevityâ¦ This is pure urban myth." - "Motors are mildly broken in by running at 3000 rpm under load at the factory (though this may vary) for the initial break-in and valve seating." There is also an interesting controversial article on the subject (it is more geared towards bikes but is still applied to cars) - http://www.mototuneusa.com/break_in_secrets.htm So if you could help at all as to what is/isn't true, it would be greatly appreciated!
