You obviously have 0 understanding of whats happening so ill do my best to no be rude.Given most of my driving is normal commute there is zero reason for me to use 93. When I go to the track I'll probably ensure the fill ups before that are loaded with 93 to ensure for max power but right now I'm on stock tune and exclusively using top tier gas only. So zero reason to use 93 right now.
Your car is 12:1 compression and these motors routinely test at 215 psi or better. Any time there is a load on the motor-- and no, not necessarily "flooring it" (going up hill, short shifting leading to a lugging of the motor, light throttle applications in high gear or on an incline, high IAT's or coolant temps or BOTH, etc etc etc) this motor will experience spark knock on 87 octane.
You can close your eyes all you want, but at least after today you can no longer claim ignorance.
Unless you plan to replace the motor soon due to busted piston ring lands, popped head gaskets, or worse, keep doing what youre doing.
Enjoy!
