Problem is, when you blend, you're really not quite sure if the particular basestocks, balanced with boron, titanium, moly, calcium additives and ester/PAO/VIIpolymer content are going to work well with another oil's particular combination.
Additives, in certain combinations, have tribofilm surface competition. That said, it might not be bad. You just don't know.
