You know most dealers do not fill up the tank with premium. For normal driving, I use 87 octane and haven't heard any pinging or any problems with my car. On auto x days or when gas prices are down, I do use 92 octane from Wawa. I never let my tank go lower than 1/4 and I usually switch on and off on 92 octane to 87.
