The best way to do that is with analysis. Short of that, all you can do is guess. If you don't do UOA, change often.

More like 5000 miles. I could increase it to 7500 miles or so because I do so much highway driving, but I drive the car pretty hard and prefer to err on the side of caution. Regardless of mileage, I would never go more than 6 months without an oil change.

Just consider the oil fully used once it's 6 months old regardless of mileage

You are referring to a Nissan dealer service manager? What makes you think he's going to say anything different than what Nissan recommends? Not to mention most dealer employees are idiots. If he says anything other than 6 month oil change intervals for summer only driving, then he's probably just another dealer idiot.

A used oil analysis is the only proper way to determine an appropriate oil change interval for your car.
