I have a 1985 Corolla with about 32,000 miles on it. Recently I have had problems with pinging on hills. I took it to the Toyota dealer and they said that it was tuned to spec, and that the pinging was due to poor quality fuel; they said that the gas companies are using "winter fuel" at this time. I have noticed that different brands make a difference, with Union 76 getting rid of the pings, and Shell the worst. Is there anything to this? If there is, what is the best brand of gas to use?

I do have the same problem with my 84 corolla and I discovered that some brands are better than the other. For example: Hess was the best and Mobil was the worst. My solution for the problem was to find the cheapest premium fuel and treat the car to it once in a while. It seem to help the problem a little even when I am using unleaded regular 87 octane.
