can anyone offer advise on the proper way to store kerosene? I have several kerosene lamps and want to put fuel for them into my long term plans. What kind of fuel is best for storage? I have heard of something called kleen fuel or something similar. Any experience with this brand? Do you recommend adding a stabilizer of some sort? If I can find/add the proper stabilizer what is the expected shelf life? Should it be replaced every few years or will it last for 15-20 years.
