The Dexos is just a formulation that GM required/specified. It is in the 5W30 Sae, Your truck takes 5W20 but, heavier use oil is recommended at the 5W30. So yes, if you are ok going to 5W30 in the Dexos 1 rated, you are fine. Long run may be better for the engine. Below is the list for the Dexos 1 blend
  • offers superb oil performance and protection to help improve engine durability
  • Exhibits improved oxidation and wear performance over conventional motor oils, which provides improved fuel economy
  • Piston cleanliness delivers maximum engine performance
  • Low volatility delivers reduced oil consumption
  • Great viscosity control helps to deliver improved fuel efficiency
  • GM-specified oil for 2011 vehicles with gasoline engines
