The basic additive package that comes from the supplier usually contains everything but the base oils and the VII.

In some cases, the author or supplier will refer to the basic additive package as the "DI" package, and define the PI package as the total basic (DI) additive package plus the VII.

So in many cases, the author or supplier needs to define the "package," or surround it with a context which defines it.

Quote:
...additives are chemicals that are deliberately added to the oil to enhance [improve base oil] properties and inhibit degradation of base oils.
