How about a little more information?

As far as the knocking and pinging:

Which car is doing this? (Between the two on your signature, carbureted vs fuel-injected?)

Does it happen at all engine speeds? Load or under load?

Cold or warm engine?

Have you filled up again with a different brand or grade and still get the same results?

Any recent tune-up work done?

Does it overheat?

Answers to these questions will help pinpoint the cause...
