I've never used 87 gas before, always 91 or higher octane. Now that I have it programmed w/ the superchips handheld I have no choice but to use 91 octane or higher. I think you will just have reduced performance if you put in 87 since it retards the engine timing to prevent knocking. I'm sure someone else will chime in here on the matter.

From what I understand, it depends how it is phrased in the owners manual. "Premium Recommended" means that you can safely use 87 with just reduced peformance. If it says "Premium Required", then you may risk engine damage as in a turbo charged car. just my .02

This is out of the Get to know your GTO literature that came with the car.

Premium unleaded fuel with an octane
rating of 91 or higher is recommended
for best performance. Using regular or
middle-grade fuel of 87 octane or higher
is permissible, but the vehicleís acceleration
may be slightly reduced. If fuel
with an octane rating of less than 87 is
used, you may hear a heavy knocking
noise that can damage your engine. In
this instance, you should fill the fuel tank
with higher-octane fuel as soon as
possible.
After fueling, ensure that the gas cap
is installed correctly and tightly. If it
is loose or missing, the malfunction
indicator lamp will light steadily. If a
loose gas cap is the cause, a few
driving trips after properly tightening
the gas cap should cause the light to
go out. If the light remains on, have
the vehicle serviced.
See Section 5 of your Owner Manual.

Im in the Chicago area close to the Indiana border and i go to Whiting and there its 3.69 regular so that makes it 3.89 premium. I have always put premium, i dont know im just scared of putting anything else.

I noticed something going through my pictures. I took this picture on 05/29/08 by my cellphone.















This was when I though gas prices are ridiculous. After that picture, within about a month the Price for 91 skyrocketed to $5.19 at that same gas station. Today.... that gas station reads $4.49 for 91. HmmMm... Remind you of stocks?

Why buy a performance car if you aren't going to spend the extra 10-20 cents for the right fuel? It only costs an extra couple bucks per fill-up.

I suggest you sit down and do some math and see how much you'll save. You may or may not get the best fuel economy with lower octane. So you may be spending the same amount of money anyway.
