With today's CNC machining techniques, an engine is pretty much broken in by 3000 miles. The recommended oil change every 3000 miles merely fills the coffers of those recommending it. A quality synthetic (unblended) with a full cotton-batting filter (no pleated paper) is recommended to be changed every 24000 miles or once per year. "Dinosaur oil", made from fossils, will break down into it's constituent benzene, varnish, etc. The only breakdown of synthetic occurs at very high temperature, which would have already melted your head and valves by that point. My five-year-old Civic has almost 100k miles with 5 oil/filter changes and takes no oil, leaks no oil, and I've had no problems whatsoever...except for an oxygen sensor at 80k miles. I plan on using synthetic for the next 100k miles. <g>

Care to show me some references so I can read up on this? I've NEVER heard of it being a good idea to wait longer than 3-4k to change the oil. I'm not saying you're wrong, but I'd like some more info.
