How much liquid does it hold though and how long would it last with normal use. I'd hate to be refilling it more often than I was putting gas in the car
The reservoir holds about a gallon. You do not have to spray that much to get a very good benefit, we typically use the small nozzle that comes with the AEM kit for installations. If you are using the small nozzle and have the on pressure set around 7-8 psi with full duty cycle by 23psi, the gallon reservoir will usually last a couple tank fulls. This is very dependent on driving style though and how much full throttle you do.
