I'll read the articles tonight, but as far as RP goes, I've been using it in my Mustang and R1 for years. Not a single problem. And I've had my Mustang completely apart and the internals of the engine, trans, and diff were pristine. So, while it may score low on these tests, it's always done well for me. As I said though, I will be reading the articles to see what's up.
