It doesn't matter much which high quality convential oil you use. Many of their sources are shared; many of their processing plants repackage for other companies. Sears oil has to come from one of a handfull of refineries, right?

It doesn't matter which high quality synthetic oil you use.

It does matter that you choose synthetic rather than conventional oil.
