Blended oils are common on the market.  I have never seen a mfr saying that
you couldn�t blend then yourself either.  Not like that on a lot of greases
though.  Read greases carefully because you will almost always find a note
on the synth that says never combine different base stock greases.

All the oil companies just say dump the oil in if it is the correct one for
your vehicle.
