I've been on this forum for a few months now and of course ALL THE RAGE is about oil, especially synthetics. Now I know that the claims are you can go further OCI's on synthetics and they protect better and cool better, etc... you get the point. Here's my question, has there been any documented case where an engine seized, blew up, fell apart, or was completely destroyed by using an "inferior" oil? Is there just one case out there where the oil itself can be clearly linked as the major, if not the only, cause for premature engine failure? There's just so much hype about which oils are best, but shouldn't any well made car or engine last long with regular oil changes on conventional oil?
