Let's see a viable source! Being that Cummins just recently made a deal with Nissan on a small V8 diesel for the Titan pickup, I find it hard to believe that Nissan would allow them to contract out to the competition, similar to Cummins being contracted to Mopar for the Cummins inline sixes found in the Ram trucks. From what I understand, Toyota isn't motivated in the least to offer diesel engines in the US market anytime soon. They are putting all their money towards hybrids and a slew of Atkinsin cycle powered engines. (Engines that run off both port and direct injection to hopefully conquer the mechanical problems associated with strictly DI engines). The "new" 3.5 Atkinsin cycle V6 found in the '16+ Tacoma and previous Lexus models, for example.
OP, as long was the Pennzoil is Dexos2 certified, I see no reason not to run it, It would definitely be my first choice! Second choice would be Castrol Edge SLX 5W-30 which is Dexos2 rated. Just whatever you do, make sure to use one that's Dexos2 certified for warranty purposes, especially with it being a new engine and powertrain design and all.
I'm excited about these new 2.8L Duramaxes, itching for one to come into my shop for a service so I can see what makes them tick!
Not sure where this Cummins in only select brands came about. You can get just about any commercial truck with a Cummins option along with the OEM proprietary engine. Cummins is in the engine business. They will sell to anyone who wants their engine in a truck. The ISB Cummins engine that is in the Ram is also offered in many medium duty trucks from other OEM's. Dodge didn't get an exclusive deal. I see no reason that if anyone came to Cummins and wanted to buy the V6 for their vehicle that Cummins would play some goofy "no we can't do that since we are already selling it to Nissan". Can you imagine them doing that with anything else? "Oh, we can't sell you a SX-15 because we already sell them to Freightliner for their trucks". Cummins sells the SX-15 to every major heavy truck maker in America. Volve, Paccar (Kenworth and Peterbilt), Freightliner/Western Star, International. And they sell the same ISB that is in the Ram as well to major medium duty OEM's also. They may have a contract with Mopar to make those engines, but that doesn't mean that no one else can buy them. Allison transmissions is the same way. Just because there is an Allison 1000 in a Chevy pickup with a Dmax engine (with GM having the authority to build that Allison 1000), Allison 1000's can be found in a wide variety of other medium duty trucks. Some of the same ones that have the Cummins engines in them.
