What kind of gas

[lacelle@frontiernet.net (Erik LaCelle)]

I'm with Eric on this.  Pointless to pay the extra money unless the
engine can do something with it, isn't it?  BTW, if your car is not
equipped with a knock sensor and you're getting knock with, say, 87
octane, most likely the problem is not the fuel but something else
(vacuum leak, cooling problems, ignition timing, etc.)

Just my .02
