I've used the Costco brand 15w/40 for the last 2 oil changes. I believe it was less than $38 for the 3 gallon box. It meets Cummins spec so there is no reason to spend any unnecessary $$ for name brand or synthetic oil.
Most people use synthetic oil simply because they believe it's "better" than dino oil and not because they live where the truck will be used in below 0° temps.
