Duplicatemovie clip problem

I have a bunch of bullets that come from a movie clip called “bullet” and i want them all to have there own seperate variable. Heres whats in my movieclip bullet…


onClipEvent (load) {
if (this._name != "bullet") {
this._x = _root.turret._x;
this._y = _root.turret._y;
this._scale = 100;
fuel = 10;
}
}
onClipEvent (enterFrame) {
this._x += 1
this._y += 1
fuel -= 1;
if (fuel == 0) {
this.removeMovieClip;
}
}

the variable is called fuel and i want each bullet to have its own fuel counter.
