Hi,
There is some pretty good evidence that changing the oil at the 3k mi. interval actually increases wear to the Engine and it's internals.
I know this seems counter-intuitive, but Engine wear actually decreases as oil ages. This has been substantiated in testing conducted by Ford Motor Co., ConocoPhillips, and reported in SAE Technical Paper 2003-01-3119.
What this means is that compulsive oil changers are actually causing more engine wear than the people who let their engine's oil get some age on it.
To add some perspective to this, I agree with the 10k mi. or annual (if less than 10k mi.) oil and filter change. Additionally, most of the dirt and particles which pass thorugh your Air Filter end up in your oil. If you live in (or have driven extensively through) dusty areas, or use a K&N Type oiled Filter, you should shorten the change interval. Hope this helps...
Happy Motoring!...Jim'99
