Engine knock/pinging on 89 octane
I know there a bunch of threads on 5.7 octane usage, but I didn't see one specifically on this topic. I have a 2019 Bighorn Crew Cab 4x4. I have a pretty long (250 yds or so) and steep hill at the entrance to my subdivision. I had noticed some knocking under load while going up the hill. Top...- Volman197020
