I have filled my engine (on the stand) with Rotella T. ( I ran it about 6 hours on cheap auto parts store oil and dumped it
to help clean inside of engine- then new rotella T with new filter)
I have been reading about the possible role of zink in the protection of flat tappet engines.
Is the consensus here that a zink additive like ZDD or Redline is a good idea when using Rotella T ?
It appears that Rotella T does have a moderate amount of zink......
There seems to be a lot of difference of opinion in places about this.......
I really just guessed that Rotella T is an OK oil for 5.9 ---------- opinions ?
