By-the-way, your are right about Duron. It is a hydrocracked group III oil. I am after PAO group IV. So far all I have come up with is Delvac1, Rotella T syn, Valvoline SynPower and Amsoil. I have never heard much on any web forum about the Valvoline product although that is what I have in my 4x4 at the present. I have also heard that Mobil 1 T&SUV is Delvac 1 in disguise.
