Which is the best oil for 6.6 Duramax?

Mobil1, AMSOIL and Schaeffers are all very good synthetics and use only group 4 or 5 chemical base stocks to make their products from. I personally would stay away from a blend of dyno and synthetic. It is still going to break down like dyno does. Also go with a good filter from Mobil1 or AMSOIL.
