The oil industry per ILSAC had to only decrease the levels of ZDDP (Zinc)
in certain viscosity to meet new emission standards. The ILSAC rated oils
still have an average of .085 levels of zinc. Testing has shown on standard
OEM set ups that used mild camshafts will still get plenty of protection
from the new rated oils. There is an exception when it comes to extreme
aftermarket applications. If you have a high performance solid lifter set
up with an aggressive cam then you will need to use a quality Racing Oil or
Fleet Oil for break in and normal usage. These oils have an increased level
of Zinc that will range from .14 to .16 and will provide plenty of
protection.
