How Often Should You Refill an HHO?

HHO cars are powered by water.

If Your Tank Is Small, Refill Often

If your tank is less than 12 inches tall and has a plate on its underside, you'll need to check it --- and likely refill it --- every week, according to HHOkitsDirect.com. This assumes an average amount of driving.

If Your Tank Is Larger, Refill Less Often

Tanks with extra capacity can last two or three months between refills at most, according to HHOkitsDirect.com. A gallon of water should last about eight weeks, according to HHO2U.com, and most tanks are about that size or larger.

Bottom Line

The size of the tank and how often you drive the car are the two major factors that affect how often you'll need to refill the tank. The smaller it is and the more often you drive it, the more often you'll need to refill it. Electric autorefill tanks that monitor the system and automatically refill it are available.
