Corvette engines and other port-injected engines aren't as subject to valve deposits from oil vaporization (volatility) like direct-injection engines such as in the Focus are, so I'm not sure how relevant that argument is.
At least the "super best motor oil in the world" freaks are mostly presenting good information in this thread, rather than ranting.
