[Morley]

I broke in my cam/engine on dino oil and ran dino for the first 25k miles, then switched to Mobil 1. The problem was the first 25k started the irreverseable process of wiping out the cam. Once the cam lobes start to go there is no stopping it, though the Mobil 1 probably slowed the process considerably. The good part of all this is that Rotella T is only about $9/gallon, is a name brand oil and is reccommended by cam mfg's to extend the cam's life.
