If it makes one feel better/safer/etc/etc/etc to chanage the oil AND FILTER more frequently than the manufacturer recommends, then that is what you should do, just don't got to absurd extremes.

I think that the oil is probably good for something close to the 15K under "normal" driving conditions, but what is "normal" and how often are we driving that way? I worry more about the filter breaking down and letting all that grit circulate through the engine. The first round of BMW long life filters were known to not last a full 15K... who would've paid for the reduction in engine life because of that??????? Certainly not BMW

Of course, you shouldn't listen to anyone about how (in)frequently to do it, but take samples of your oil every now and then and have them analyzed and then go by that to figure out the frequency of oil changes.
How many posts could a repost post if a repost could post posts?
