This is the first UOA for the 5.0 since I bought it. I didn't bother with the oil that was in the car since I had zero info on all the details. As the title says, M1 5w30 with 4250 mile on the oil. Mostly to and from work, a couple small road trips, and the very occasional quick acceleration. Oil life meter was at 10%, but I was headed on a long road trip and didn't want to wait. Same oil went back in.
