My dealer told me to run 87 octane gasoline, another said 93 for best results. What are you guys running?

I asked the same question many posts ago. The vast majority of the club say's run Regular. I tried a couple of tanks of Premium then went back to regular. Most of the members believe or have stated that Premium will slow the car down. I really don't know. I run Regular and when I hit the gas pedal and climb to over 4500 rpm I hear some detonation.

Is this pinging sound kinda like the synchronizers in the tranny are going out? I noticed particularly while cruising in 5th, that if I accelerate hard it sounds like the 5th gear synchros are going bad. Is this the same noise you guys are talking about?
I know I'm going against the grain here, but I stick with premium. Why?, you ask....
Well, I don't trust the average fill station. Do you know if you're really getting the grade you want? I doubt we always do and, therefore, buy a higher grade to try to make up for irregularities. I hear all sorts of crap about what really goes in the tank wells.
Also, I know I want power from my Bullitt. But I do not want detonation, in any form. I can hammer this puppy all day for years without detonation. Maybe loose a few horses, but not my piston tops.
I guess I want this stang to last a while. A rebuild would severely reduce it's original value to me and I think to any collector. If Ford Service is under my hood for more than a moment, I get really wary. They'll undoubtedly screw up something else.
Just my .02

The ping in my car has been driving me crazy ... even with 89 octane I still had it alittle at WOT with max ac on. Took it to dealer just now for TSB to fix pinging. Also found (1NastyGT/Bob had suggested this also) that our gas at least in the greater Detroit area is oxegenated for the summer months. Was told by the service rep that in the winter we will return to "normal gas" again until next summer. He stated a lot of different models are coming in with pinging problems this summer.....My hopes are that now I will be able to use 87 octane...
