Can I use unleaded gas instead when Coleman® Fuel is recommended?
Unleaded gas should only be used in Coleman® appliances marked as “Dual Fuel™” or Unleaded Fuel” and only the lowest octane unleaded gas available should be used. Unleaded gas contains additives that are more difficult to vaporize than the gas itself and the higher the octane rating of the fuel, the more additives mixed with the gas. Unleaded gas from Canada should never be used in any Coleman® appliance, even the “Dual Fuel™” and “Unleaded”, as there is an additive in the fuel which will damage the tank, valve, generator and burner assembly.
Coleman® “Dual Fuel™” and Unleaded” appliances have been designed to handle the additives in unleaded gas. The use of unleaded gas in any Coleman® appliance designed for use only with Coleman® Fuel can result in a rapid build-up of carbon in the generator and damage to the rust-resistant coating inside the fuel tank. The cost savings in using unleaded fuel in a Coleman® Fuel appliance would be rapidly offset by the cost of replacing the generator and eventually the fuel tank or entire appliance.
QUESTION
What is Coleman® Fuel?
ANSWER
Coleman® Fuel is basically petroleum naphtha with a bit of rust inhibitor. It has an octane rating of 50 to 55 and none of the additives found in gasoline. It has a lighter molecular weight than gasoline, kerosene and diesel fuel and cannot be used as a substitute for any of those fuels. The flammability of Coleman® Fuel is comparable to gasoline but it cannot be used in gasoline engines. It will burn out the valves.
QUESTION
What is the shelf life of Coleman® Fuel?
ANSWER
An un-opened container of Coleman® Fuel stored in a dry area with no rapid extreme changes in temperature will remain viable for five to seven years. An opened container stored in the same area will remain viable for up to two years though will be at its best if used within a year.
Coleman® Propane Cylinders can be stored indefinitely in a dry area. The propane fuel inside the cylinder will not break down.
