The only place I've ever seen a 'chart' for comparison purposes is on the many Amsoil independent sites, which I'm not going to rely on. There's no telling how old the information is, and I have no reason to believe anything Amsoil has to say about Mobil1.
Mentioning old information, the link you posted regarding Mobil 1 Noack volatility numbers was dated January 29, 2010, three years ago.
