C2 of the Year Finalist - Modified 2020
I will go out on a limb and say many run 91-93, some, including myself run 89. It will depend on how an engine timing is mapped, known compression ratio, driving environment and how fresh or tired an engine might be. I sure others CF members will share their own details.

93 octane, Shell. Their detergent package gives them 'Top Tier' rating I believe.
