How long will the fuel last in my tiki torch?
Tiki Torches can burn for different periods of time based upon their type of fuel source.
Portable, free-standing torches using citronella or kerosene will burn until the oil is consumed, which is determined by the size of fuel canister used. Generally, 5 to 10 hours or longer depending on the canister size.
Permanent torches, however, can burn much longer and require less maintenance, such as refilling fuel and replacing wicks. Natural gas or propane torches can burn indefinitely, and are controlled by lighting or extinguishing the torch at will. Torches connected to fuel tanks will burn for periods determined by the size of the tank…. more
It really depends on the fuel you use and size of the wick. This blog post goes into a lot of detail. Looks like an average torch will burn for about eight hours.

The length of time your torch’s fuel source depends on the fuel and on the source. For instance, paraffin or citronella oil will last anywhere from 6 to 16 hours depending on the size of the oil torch (larger torches usually burn longer). Keep in mind that you should not switch oil types for the same wick. Gas torches using propane vary according to 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.
