Have any of you guys changed your oil yourself? Well I just changed mine at 3200 miles 2020 Duramax. When I fired it up that knock/thump sound just multiplied about 20X until the oil filter filled up and oil started to circulate. Way more noise than any oil change I've ever done It sounded like a knock and not a thump at that point. I felt like damage was in progress while waiting for oil pressure to build. Change the oil filter to hear for yourself.
