    having never owned a car with power steering i could do with some advice. 1) am i right in thinking the resevoir is the small tank to the front right of the engine bay, labeled "hydrolic fluid". 2) if so it says to use only mineral based hydrolic fluid, is all power steering fluid mineral based?. im at my girlfriends at the moment and have noticed that the (possible) power steering fluid is below minimum, we have some fluid here but it doesent state if its mineral based or not, will it matter?

    Please don't be tempted to just put in regular PAS fluid!
    Seal failure in the pump and rack would result, with major leaks.

    If the pump isn't noisy, it's still ok to drive, till you get the right stuff.
    This is what you need:

    A slight change in pitch when turning the wheel lock-to-lock is normal, low fluid will cause more of a groan.
