In this log, I was driving my stock Cruze 1.4t with a tank full of 93 octane Mobil premium fuel. This car is very low mileage and automatic. I had such horrible audible pinging with over 12 degrees of KR at part throttle low RPM, that I suspect the fuel quality was absolutely horrible. It also happened right after many minutes stuck in traffic so it got a very good opportunity to heat soak the IC, in 85 degree afternoon temps. Please look and comment if you can.
