I dont think you need to run anything different. A quality Xw30 weight oil or possibly Xw40. I personally run GC 0w30 when I can.

10w40 will work great

I was running the GC 0W-30 but since its not available around here any more I switched back to Amsoil 5W-30. The lower viscosity at startup with the Amsoil quieted down my Morel lifters as a bonus. They always ticked on first start with the GC which is a higher viscosity at normal temps. Think it was just too thick for the lifters.
