I would say you can run any brand you like as long as it meets the viscosity and duty-cycle requirements specified by DC. I don't have my owner's manual in front of me right now, so I'm not sure what API rating they specify but I'm guessing it will be SG or SH. But I do remember the only viscosity specified is 0W40.
As far as brand preference goes, I'm a Mobil-1 man myself but I have had good results with products from Redline, Royal Purple, and Amsoil as well.
