The unsolvable debate, change oil soon after purchase or wait for the OCI to say do it. I was going to wait, partly from doubting its necessity with today's engines and partly from cheapness. The local Christian Brothers just announced an oil change special for $14.99, eliminating the cheapness argument, so I'm going tomorrow and get it changed. I'll have ~425 miles or so at that point, enough that any wayward particles should be removed. And small side benefit going forward I'll have July 4th every year as my oil change reminder.
