"the new diesel oils have also had the zinc / phosphorous pulled out of them - you need to use an additive or the brad penn type specialty oils to be sure. Red STP also has zinc / phosphorous but I'm not sure how much. Cam break in lube additives are full of it - so you can use that or GM EOS at each oil change as insurance."
:o CRAP!! When did Rotella and Delo remove their anti-wear additives?
So is adding STP or cam break-in enough? And how much?
And how safe is my flat-tappet if I use a good synthetic like Mobil 1 or Royal Purple?
And here's the pandoras box: what about ProLong/Duralube/Slick50, etc??
I've been doing the following for my 350 flat-tappet street motor: 4qts Rotella, 1qt Mobil 1, and a half bottle of STP. Thoughts?
