LoL ... "leaps and bounds ahead"? I don't think so. Per the Amsoil efficiency graph the Ea has worse efficiency than the Ultra, so how can it be "leaps and bounds ahead".
And actually, if you go to Mobil 1 website, they don't even list the efficiency anymore. Usually, when a company stops listing the efficiency in terms of "xx% @ yy microns", then they are trying to hide an efficiency that looks pretty bad compared to others on the market.
