I had a higher compression Buick and it would ping like crazy on regular 93, putting 5 gallons of av gas to a tank eliminated the ping and never an issue with the carb.
I also ran it in my outboard drag boat with zero issues. I was told that the rating of 100 octane was a min rating and it could see higher numbers.
