All diesel oil sold off the shelf ha..s very little bennefit anymore. The diesel particulate filters will not allow any good metals compared to three years ago. And I have seen and read a very detailed study comparing 10 different diesel oils on another websight that I am a member of, "TURBO DIESEL REGISTER." Rotella ranked lower than wallmarts house brand. Valvoline Premium blue was way up there as far as Diesel oils go.Has anyone ever heard of diesel oil being good for flat tappet cam break in? Advice from a friend of mine, not sure if I trust it?
X2! can't remember which one it was, but one of them purchased myBrad Penn and Joe Gibbs both make specific break in oils for engines. THESE ARE THE ONLY 2 I WOULD TRUST AT THIS POINT FOR ANY FLAT TAPPET BREAKIN.
Didnt we have this discussion in O.W. a six plus months ago and determined that the removal or reduction of ZINC was the reason that most oils arent sufficient for flat tappet cam break in???I'd just throw a bottle of EOS at the Rotella, and then dump it. You don't that crap in there any longer than it takes to break in the cam. From there I would start running either soemthing like Brad Penn, or add some ZDDPLUS to each oil change.
Hammerdown, Brad PENN is precious and $$$ to be breakin cam in with. You don't want tht oil in there for maybe a hour or so, and dump it.
