Here we go another oil thread....
I change every 5000 miles on the clock with generic dino oil at the dealership or the local shop.
All modern SAE oils are good enough for the type of driving we do in these cars. You can safely go 7500 miles, I just do it at 5000 because it's a round, convenient number.
If you put synthetic, you should be fine for at least 10K miles. Changing synthetic every 7500 miles or less is a waste. Unfortunately the user manual does not make provisions for long oil-change intervals with full synthetic, that's why I stick to dino oil @ 5000 to be within the requirements of the maintenance schedule.
As for the first oil change - I would not rush to drain it too soon. Break-in does not put more wear on the oil - it's the oil filter that captures all the metal shavings. Some manufacturers (like Honda) used to put break-in oil, rich in molybden, and you were supposed to keep it in for the first 5000 miles. Nowadays nobody says anything about the first oil, so it may be spacial it may not, but there isn't a good reason to drain it too soon.
