Which is also one of the reasons I disagree with using a specific brand of oil solely based on its additive package levels (the majority seems to assume that more is better). For a 1qt bottle of oil, the more additives you add, you're giving up something else.
The obsession of highly concentrated additive packages has been made a big fuss of by places like BITOG and the availability of cheap oil analysis tests that report the chemical composition of a sample of oil - without regard for the actual overall performance of that oil. Producing a good oil is much more involved than stuffing a load of calcium, moly, ZDDP or other magic compounds into the bottle.
