I live in NY annd around here they sell 91,93 or 94. I was just wondering if putting 94 in my car everyday could be harmful. My car is currently in the shop being BPUed but I will be keeping my boost at 11PSI most of the time. Usually when I'm driving the car I barely take the car above 2700RPM. Should I only put 94 in when I want to boost or is it safe for everyday driving?
