I have a 2014 GMC sierra 1500 with a 5.3 L. I recently had a remanufactured engine installed because of the oil problem these engines are known for. Long story short, the dealer put in a remanufactured engine in place of the original. My first oil change with this one is due. What is the recommended type of oil and weight should go into this one? It has a little over 5000 miles on it.
