The duration a Coleman camp stove can run on one tank of fuel depends on several factors, including the type of fuel used, the stove's heat output setting, and the tank's capacity. Coleman camp stoves commonly use propane or liquid fuel (white gas) as their fuel source.
Propane Stoves: Propane canisters used with Coleman camp stoves are available in various sizes, typically ranging from 1 lb (16 oz) to 20 lb. A small 1 lb propane canister can last anywhere from 1 to 2 hours of continuous cooking, depending on the stove's heat setting and burner usage. Larger canisters will obviously last longer, up to 20 hours or more for a 20 lb tank.
Liquid Fuel (White Gas) Stoves: Coleman liquid fuel stoves have a fuel tank with a different capacity. The runtime on one tank of liquid fuel will vary depending on the model, heat output setting, and the size of the fuel tank. As a rough estimate, a Coleman liquid fuel stove can run for several hours to a few days on one tank of fuel.
Keep in mind that these runtime estimates are approximate and can vary based on factors such as wind conditions, altitude, ambient temperature, and how often and at what heat level the stove is used. To get a more accurate idea of how long your specific Coleman camp stove will run on one tank of fuel, it's best to refer to the stove's user manual or consult the manufacturer's specifications.
Also, remember to factor in some extra fuel for safety and convenience. It's better to have more fuel than you think you'll need, especially when camping or cooking in remote areas where resupplying might be challenging.
