I have a 1998 F 150 4.6 8 cylinder.... Problem is that when i use 87 octane it pings like crazy when I accelerate. I put in 92 octane virtually all the pinging goes away. Any suggestions on how to address this? Or do I simply get used to paying for 92 octane?

No just fill up your tank and put a bottle in....that's it for now. It will clean out carbon deposits and trash/dirt/water from your injectors/fuel system. Report back after the tank of gas is gone....
