Coleman fuel
Coleman fuel is a mixture of cyclohexane, nonane, octane, heptane, and pentane.[citation needed]
Though Coleman fuel has an octane rating of 50 to 55 and a flammability similar to gasoline, it has none of the additives found in modern gasoline and cannot be used as a substitute for gasoline, kerosene or diesel fuel in modern engines. [citation needed] Its high combustion temperature and lack of octane boosting additives like tetraethyllead will destroy engine valves[citation needed], and its low octane rating would produce knocking. [citation needed] However, it is quite popular as a fuel for model engines, where the low octane rating is not a problem, additives are unwanted, and the clean burning, low odor and longer shelf life are considered advantages.
