I know this isn't what you asked but for information purposes only I figured I'd share. After all the oil vids/discussions that came out I switched to Amsoil 5W50 due to it being the only oil certified to not cause the carbon buildup that makes are cars blow smoke when at WOT due to our GDI. Mine used to blow out the smoke after minimal miles using the 5w30 Mobil that came from the factory, it now no longer does and truly runs much smoother.
