tom, new engines, new metals, closer tolerances due to better machining have certainly played a role in replacing old tech. as for the myth part, can't agree. there was a time when you couldn't go too much past 3000 miles due to oil breakdown. a long with the new tech, came such an improvement in oils, it might be safe to say that the new dino oils are as good as the synthetics from 20 plus years ago. along with the new tech, and better oils, engines have increased oil capacity which also plays a role in the longer oci. 350 engines in the seventies only held four quarts. not saying you can't do the extended amsoil thing, but its not for me. also, chrysler doesn't have to prove anything, they just ask to see your receipts from your oil changes.
