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 longevity⦠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!
