BTW they are pulling all the zinc out of the diesel oils now as well. I am currently running Shell Rotella T in everything (same thought process as the delo), but haven't decided if I'm going to change anything yet. I have ZDDP for the break-in and the first oil change after that while the new engine takes a set. I've always been a proponent of sticking with the same oil every time, but if the oil companies aren't going to keep the oil the same, it kind of defeats the purpose.
Coatings! Coatings are the future!
