Paul, If the engine isn't running hot, it's in time and spark advancing is working properly and a tune up has been do then it normally shouldn't Ping with 87 octane unless you got some bad gas.

Now that the car is quieter, I can hear it ping when I gas it hard to accelerate. I currently use 87 octane (or whatever the lowest regular gas is). Would a higher octane eliminate the ping, or is there an adjustment I need?
