I'm not a mechanic but the man that touches my vehicle is one of the most highly regarded in South Bay Ca. That's not an easy award to earn.
Synthetic will go black same as 10/30 or 10/40. Keep waisting your money.
I change mine every 3,000 miles and am pretty darn good about it. I once pulled a cylinder head off a chevy V-8 that had 150K on it (this was in 1985) and the guy changed the oil every 2,000 to 2,500 miles and it was spotless. But you can get away with more in today's motors because the tolerances in the cylinders are so much tighter.
I'll always say that changing the oil and air filter REGULARLY are two of the cheapest things you can do to protect your motor, but you can get away with being less diligent with today's equipment.
I was looking for a car for my buddy and ran across numerous ones with 225K miles plus that didn't use oil. They just make 'em a little better these days.
