with most motors this is true and i would recommend a change at 500 but lately a lot of companies pre-run the engines for the initial wear and tear then flush and refill the system before it is put in the car. Toyota does do this with the yaris motors, but if you want to be on the safe side, do an oil change early on.
I know oils have been better detergents in them now but I don't believe in the whole 5k mile oilchanges. I don't see how suddenly recommendations jump from 3 to 5k. I have seen tests where engines are ran for 100k miles on a single oil with the exception that they only changed the filter every 3k and added as needed, the engine showed no difference in wear and tear from one that had the oil completely flushed. Once again though, I wouldn't rely on that information either.

I personaly change every 4k with full synthetic.
