using the largest jet on 18psi you could get in a whole night at the drag strip (about 10 passes). Just driving it aroun it could last as long as you wanted it to as it onl injects when you boost. Drive conservatively and you will never go through a tank, drive hard and it will be used up kinda fast. I am using the smallest jet though and am only boosting 12psi so even seeing the boost while driving I should be okay. I will keep a gallon container of washer fluid in the trunk to refill it anyways......
