GM sells EOS oil fortifier which they recommend for break-in on any of
their HP cam engines and sounds like it would be good for long term
use. Also CD-2 and SLOB are oil additives with Zddp. We may have to
watch to see if these products are required to reduce Zn like engine
oils. Ive been using Valvoline Racing oil VR-1 20w-50 ,which says it has
higher levels of Zddp, along with the EOS. John Mitchell 76 TR6(with
all it's cam lobes, so far)
