I saw this last night lol I think I am going to be putting mid grade from now on on my 2024 I was told that Shell gas is the best.Ran across this in my feed. I don't see a lot of Mazdas in these videos.
I think you may have understood that the wrong way round. LOWER octane fuels are subject to detonation (knock) and THAT can burn holes in pistons, etc.I had a mechanic tell me that higher octane fuels can burn holes in your pistons, plus a whole other myriad of problems.
