Just purchased a 2017 Ram Crew Cab 1500 Laramie with a 5.7 Hemi. I was all se to buy a f-150 with the Eco-boost but the dealer gave me a really good price. The engine is bigger then what I needed. First what oil recommendation? It's still under warranty so I am thinking it has to have the Chrysler oil requirement? I was hoping to stick with Valvoline. I am new to dodge I was a Ford man. Can you give me any information on the Hemi? It would be greatly appreciated.
