    For the WRX, its highly recommended for the longevity of the car to use premium fuel, i.e. 91 or higher octane. It even says in the manual that you can temporarily use lower octane, but only until you can find a 91 octane gas station. I know it hurst the wallet..but you paid for a performance vehicle, and it needs performance quality fuel.

    run regular through your car and you'll definitely be able to feel the difference and want to put 91+ back in ASAP.
