There have been many discussions about fuel storage, but I have a kerosene/paraffin question. I have a diesel sailboat engine in which I always add a biocide to stop growth inside the fuel tank. Should our kerosene fuel get the same treatment? I have 2 1/2 gallon containers and it may take me several years to use the fuel. For that matter, will fuel sitting in an unused stove also support growth? I know, the obvious answer to to burn more kerosene to keep it from going bad.
