Foaming? Never had that issue with Rotella in my Powerstroke anyway and have racked up a pile of hard towing miles over the years on it. You can't go wrong with Rotella T6 or Mobil 1 Turbo Diesel Truck, they're both excellent HDEO's, Amsoil and Shaeffer's won't do anything different except drain your wallet quicker!
