Thread: Engine Oil +

Great advice from Tech on this, I am no expert here but I might add one thing Isky sent me with my last cam I found interesting, they state that cam lobes get oiled mainly by the oil film in vapor form from the engines bottom end and that todays thin weight oils don't provide amble film and recommended going to a thicker viscocity oil for flat tappet cammed engines, all this plus needing the zinc zddp as stated. On another note they where huge supporters of Brad Penn motor oil and in a nut shell only recommended their oil for break in and running, I called Isky's tech on the phone and asked if I used Brad Penn oil if I needed to add additional zddp additive for break in and they said "NO" as it is the perfect additive package for flat tappets off the shelf and adding anything will ruin the chemistry package that they have. Of coarse I read all this after running regular oil in my other rod for 15 years with a can of STP with each change (Its still loaded with ZDDP, I assume similar to the extreme pressure lube Tech recommends) Anyway Brad Pen oil is pretty reasonable when you can find it, as I gave a local dealer $60 per case (yes $60 for 12!)
