A girl called in to ask if it would be OK to put some remaining OLD Coleman camp stove fuel into her (now nearly antique) car’s gas tank. (Answer: Basically, why bother?)
It reminded me of a time I got to speak to an executive of the Coleman company. He told me that there was no reason at all to buy Coleman fuel, which is naphtha. About the only reason to buy their naphtha is that it has a much longer shelf life. Modern unleaded fuel is just as good, not nearly as expensive, and readily available right down the street (as long as the local electricity is working). It’s all I’ve used in my Coleman lantern and stove in the last 35 years. He said even leaded gas could be used in their products with no detriment. Of course that’s a moot point since leaded gas is no longer available.
The caller also stated that Coleman lanterns run on bottled propane. True, you can buy a propane fired lantern, (or stove) but the gasoline ones are still available. They just require pumping.
