No idea how it might apply to this situation but I had an 86 Suburban that pinged unless I ran midgrade fuel - until I changed out the valve seals. After a bit of running it was happy with the regular fuel and had more power and made better mileage. Maybe the oil being burned contributed to the carbon buildup?
Do you get any blue smoke on first startup? That is what my truck did and what caused me to change the seals.

If I agree that it should not ping, what specific steps do I take to find out and then remedy the problem?
