One of the things that I thought was interesting was the high silicone level, which they say can be due to recent repairs or from dirt bypassing the air filter. While I have had the front cover off to repair the timing chains, it was a couple of years ago. Last week while replacing the air filter, I noticed the rubber air ducts were split, which could be a place for dirt to enter.
As far as me extending my intervals, I'm debating it. I'm so used to doing 7500 intervals and it keeps me inline with Nissan's maintenance schedule and it's a good time to rotate my tires, as well. It's also good piece of mind that if I'm a little late on my oil change, the oil is still in good shape for a couple of thousand miles.
