By the advice he gave you the dealer probably believed the engine was pinging, but switching to the higher-octane fuel did nothing to fix it. The car is still under warranty, so take it back to the dealer and ask that it be fixed again. If they can't fix it, ask them to consult Ford about the problem. Persist until it is fixed, long term pinging can cause damage to the engine.
