That's great...

I've been running 87 octane per the owners' manual, but the car does ping very slightly when lugged (before it downshifts on hills, even on "S" setting). I will try a tank of premium and see if I gain any MPG. I would have to gain at least 8% MPG to break even on the increased fuel cost.

The car runs very smoothly on 87, and it's dead flat around here; the only hills (where it will lightly ping for a second or two) are when I drive elsewhere.

How much of your improvement do you attribute to the new plugs, and what were you getting before?

Bob
