    2003 WRX Fuel Type

    I just picked up a 2003 WRX Wagon. As we all know, it is suggested that this car be fed Premium gas. However, I am a poor college grad, and I did not buy this car primarily for its performance capabilities.

    So, my question: If I feed my WRX anything below Premium gas, will I only diminish its performance, or will I be doing the car any undue wear/damage?

    Thanks,
    Eric

    main issue is detonation, where the gas just randomly explodes before the spark. you hear it as pinging and most people just think its annoying but it can mess up your pistons pretty bad if given enough time
    If at first you don't succeed, skydiving isn't for you.

    Not to sound mean at all because I don't want to come off that way but it the maker of the car suggests Premium Fuel only, I would think that since they made the car I would just do what they say. I went from a regular gas car to a turbo and I learned about the detenation problem and I wouldn't ever take that chance in messing up my engine.

    so, I would just stick to the suggested fuel to use.

    91 is for pansies

    but seriously dont use regular 89 or 87, the car will run like **** and you can definitely destroy it. It's the same as using the wrong oil.

    A bit off topic, but why didnt you get the base impreza if you don't want the performance of the wrx?

    PEOPLE!!! For real? Lets do the math, typically youll see premium .20 to .30 cents higher than regular. So were talking $5 more a fill up at the max compared to using regular. If $5 makes that much of a difference for you, you should be using public transit and sell your car.

    First of all, thank you everyone for your advice - I would have never known about the detonation issue.

    In response to the above quote, it's not as though I was unaware of the base model or the capabilities of the WRX. I definitely want the capability to perform, but my primary concern was not strictly that. I want have it when I need it, even if I don't use it all the time.

    ...plus, the WRX looks ten times sexier than the base.
