All our work orders where I work nights either say Castrol Bulk or Castrol Synthetic so when I do my changes I grab a Castrol that meets the spec of the car.
Would I use Castrol in my car? No, I prefer running an under-rated oil like QSUD to an over-rated oil like Edge.
And I wouldn't even put GTX in a lawnmower.
