Well it's more so that when driving with the headlights on, it's decides
that every 5th spray needs to turn on the headlight washer. However, if I
just use it once during my evening trip home, it will still use the fluid.
I've found that when I am using it , it's usually at night and I ran 10
days - 2 weeks before having to refill the tank. My wife's car uses a full
tank every 2 months approx. and she LOVES to spray her windows all the
time...
