Well, just a little. ;pg; Really though, Mobil-1 and Amsoil are the only two to use true synthetic basestocks (and have it backed up with industry certificiations in Mobil's case) whereas the rest are synthetic blends. Remember that synthetics aren't regulated in any way, you could by used oil by the drum and re-bottle it with a drop of synthetic and market it as the best 100% synthetic known to the galaxy.
