Excessive oil changes are not doing any engine a favor. Of course, the greedy big oil industry likes to siphon off consumers hard earned money if they can, but consumer groups called them on this and even the greedy big oil companies are now no longer recommending needless and wasteful 3,000 mile drain pain intervals.
