I had a similar question about break-in periods and oil changing, so I asked the Service Manager at my dealership, and he told me that "all Nissan engines are run for the equivalent of 500 miles before being installed in the car, and therefore no break-in period is necessary."
Can anyone confirm or refute this?
The same service guy told me that I can change to full synthetic right away (not waiting until 3,750mi), and advised me to always run synthetic (not switching back). I can confirm that at least the second part of that statement is good advice, since running synthetic, then switching back to conventional oil, may cause leaks due to seal shrinkage.
