I don't trust the government, that's why I collect my hair.
just put 91. You can actually damage the engine if you put to low of octain due to our higher compression ratio. 91 or higher only.

I would think in theory the ECU should retard timing to compensate for a lower octane gas, thus causing you to lose power.
However, why would you even bother? If the extra 15-20 cents a gallon is going to break the bank, you should reconsider your purchase.

Read up on what Octane means...
It doesn't refer to better gas.
With our engines compression ratio 91+ is a must. I've only used 93 except like someone mentioned during the gas crisis.
87 is no good for this car.
