It varies from dealer to dealer. Whichever approved oil they can get cheaper.
In my experience Dealers will use what they can get the best deal on. Mine uses Valvolene semi synthetic. I supply my own Penrite GF5.
Dexos 2 I though for our cars you must use Dexos 1
See posts 18/19. I made an error
My dealer use AC Delco oil, blended locally by Fuchs.
Is that the dealer you purchased your Magnum from?
Each 'stealer-ship' is different. The oil they use will depend on the contract they have with their supplier. Cheapest supplier usually wins.
To make it even more confusing, there's a 'Dexos 1', a 'Dexos 2', and a 'Dexos 1 Gen 2'.
Dexos 2 is designed for diesels, so even though it may be fine for your petrol engine (it'll certainly keep it damn clean) Dexo 1, or Dexos 1 Gen 2 is what's intended for your petrol engine by GM. Clear as mud?
