It says 1140 ppm for zinc. So thats more or less the same as before.
I'm waiting to see a Virgin Oil Analysis for the T4. Everything else is conjecture

I did an oil change today and filled up with the T5 synthetic blend with a mobil M1 301 filter. I also ran a half can of seafoam in the crankcase before draining. Motor runs great now...
the oil that came out was quite thick and dark so i guess the seafoam did something. I'll be doing the valve covers over christmas and looking fed to seeing how clean it is in there

Castrol has a diesel engine oil that has 1300ppm of zinc (pretty sure that's accurate). I think it's 15W-40 too. I haven't tried it personally but I don't see why it wouldn't work.
I have tried Rotella before. Never noticed a difference in anything really with the Castrol GTX that I usually use. Except that it got dark fast and it was more expensive. I am pretty sure that the regular GTX 10W-40 has 1000ppm of zinc. That's what I have been using for years and never had issues with it (2k mile intervals).

On the subject of diesel oil, I have been using an additive called Archoil AR9100 for the past 5k miles. I know that this is a must have for Ford Powerstroke engines and other diesels for easier cold starts and a few other things I can't remember. Overall, it seems to make the motor run a little smoother which is one of its claims. I think it's a good additive to try to see if it makes a difference. I thought it was snake oil, but it actually makes the motor feel smoother.
