Thank you for this thread and site. Just bought 2020 Sierra with the 3.0 Duramax and had never owned diesel before so was pretty overwhelmed reading the manual. However many of these posts put my worries at ease. Now if I can figure out how to remove the rear view mirror cover so I can hardwire my radar detector\dash cam combo without destroying it....lol Pics: https://1drv.ms/u/s!Au8KKHL6Oauug4VZtJ_yrAnE6wB0zg https://1drv.ms/u/s!Au8KKHL6Oauug4VaKSw06WAhkfqDgg
