Have only been in TX for 2 years, and only started going with higher grades gas once we got here. Back home in Chicago I ran 87 year round in all my MBZs, never heard pinging until I got down here. I think 95 degree Chicago summers are more brutal because of the high humidity, but realistically down here in TX it's not uncommon to go well above 100. That's when I start hearing pinging and at that point I will always run 93 as insurance. The heat really has a lot to do with it.
