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.

I use Rotella. Your owners manual will give you some idea based on what you plan to do with it.

I always let the Ford dealer do my changes on my vehicles including my diesels. They use standard Motorcraft unless you want to pay extra for synthetic. Between the DW and myself we have driven well over a million miles in our lifetime using standard oil and never an engine failure or ever one that used much oil.

I use Mobil Delvac 1300 15W-40. I tried Rotella TTT, but the numbers from Blacksone labs went up with Rotella, and back down with Delvac. So now I just use Delvac. Nothing but raves from Blackstone so I'm happy.

I ran a short oil change due to a long trip in the near future, and this is what Blackstone Labs said, "While it's impossible for there to be absolutely no bearing wear in 4,599 miles, it is possible for it to be so low that we can't measure it, and that's what we've got here."
