Chevy demands Mobile 1 Syn in my Corvette, even has it on the oil fill cap. It is of course a gas engine. I don't think Chevy is not recommending it. My friend has a 2016 GMC 2500 Diesel and has synthetic for diesels put in at his changes.
Check your owners manual for the proper oil to use.
See if Mobile 1 is also made for diesel use.
