Which diesel engine oil.

Ordered a 2019 F-350 with the 6.7 diesel. Trading my Triton V-10 gas.
I always used Valvoline. Never had an oil issue.
Never had a diesel. There are several brands of oil out there You guys are the experts. What oil do you use?. Is synthetic my only choice?
Thanks in advance

    If you like Valvoline products, Premium Blue Extreme 5W40 is a good choice like 2naEagle uses. Also Rotella T6 5W40 is another good choice.

    I would not use Delo and Delvac since they're both dual rated for gas and diesel engines and have reduced Zinc and Phosphorous anti wear additives.
