Saw this regarding GDiesel, anyone else heard anything on it? Seems almost too good to be true, but the US military doesn't have doubts so maybe I shouldn't... Very curious to hear a knowledgeable perspective on this. If a 2009 ML350 bluetec went from 24 to 36mpg, I can only imagine the benefit on my 335D
