I just got the valve stem seals done, so assuming its still not burning a quart every 150mi then I will be getting Rotella-T 15-40 changed ASAP. I hope it will clean up the 'red' valvetrain a little better than the current 10-40 I am using.

So, based on that I know about the differing cams now, would it be safe to say that Dino oil should absolutely be used in any early 103 using the earlier tin-plated cam design? Is it still recommended on the updated design too? Just so I know for future reference and knowledge.
