How long will the fuel last in my tiki torch?

The length of burn time expected before you are out of fuel depends on the fuel type and on the source of that particular fuel. For instance, paraffin or citronella oil will last anywhere from 6 to 16 hours depending on the capacity of the fuel chamber (larger torches usually burn longer). Keep in mind that you should not switch oil types for the same wick. Gas torches using propane vary per the size of your tank. If your natural gas torch is hooked to a natural gas line, it can burn almost indefinitely, though all torches require periodic cleaning to remove debris and maintain safety.
