I'm not buying it.
I had a modified WRX and a supercharged T-Bird, both running on 91 & 94 octane and never had an ounce of ping.
I've recently switched from the economy tune to the 91 tune and haven't detected an ounce of ping.
Maybe the additives in the Shell gas? Or maybe the station just had water in their tanks???
