I would not run 5w50, the truck runs the same oil pressure, so you're just getting a lower volume of thicker oil through the engine. If you run it hard and oil temp is consistently above 230 or so, 5w40 helps keep the pressure up when it's hot. But 5w50 is not needed and doesn't really help anything.mobil1 5w30, going to switch to 5w50 soon i think
id probably switch to amsoil, but its not readily available at the local meijer.. however thats what is in everything but the engine/trans.
