My 2005 had a problem with pinging on 87 octane fuel. Any 87 octane fuel. I had it to my dealer multiple times as the manual said it is not recommended that you run any higher than 87 octane. I was concerned about damage over time. My dealer tried lots of things, but could not fix it. I continued to schedule appointments to have it fixed. Finally they called out an engineer from Ford to investigate. He recommended the dealer try some things and said that if the car is still pinging in 30 days he would come back out. After a month and a half, I called the Ford customer service center, who is useless for anything but documenting the problem you are having and notifying your dealer that someone is displeased with the service they are receiving. The very next day, my dealer called and said the engineer was coming out to see my car again. I sat down with the engineer and my service manager with a prepared list of questions, most of which the engineer answered to my satisfaction. The result of the meeting was this. We can't fix your car, but we (the engineer) wants me (the customer) to be happy with my new car because Ford is not doing well right now and they need all the repeat business they can get, so he offered me a new car or a free extended warranty. The Ford engineers have the power to make these decisions. I took the car. They expedited the build process, and it was serialized just a week or so after the final approval. It was agreed by all in my meeting that they could not recommend higher than 87 octane, but I would use whatever octane level was required to stop the pinging. It was agreed that I would run whatever octane level is necessary to stop the pinging and that my doing so would absolutely not void my warranty and they would have no way of telling what octane level I was running anyway. That's my story in a nutshell. The new car is great. Lots of improvements for 2006. Runs good on 89 octane (BP). Pings like mad on 87 octane (BP). The point is that you should try to get a Ford engineer involved with your problem, especially that yours is a potential safety issue.
