Re: Kerosene Shelf Life FYI
I've been using both a kerosene heater, and lamps at our cabin, with good results. I too have used "older" kerosene that worked just fine. Here's one thing though that you can do with older fuel that might have absorbed some water. Cellulose has a strong affinity for binding water, so if you have some older kerosene you're doubtful of, filter it first through a wad a cotton paper towels. Rust and small amounts of water both get caught up in the cellulose.
Another thing though is that I think kerosene might be light sensitive. I bought and old glass yard sale lamp that was yellow in color. I discovered that the kerosene had turned yellow, and there was a yellow film of varnish on the inside of the glass. After cleaning it out with paint thinner, the glass was perfectly clear again. I suspect the lamp had sat out in a sunny location for years and had degraded in the sunlight. So, if you buy any fuel in plastic containers, keep them out of strong sunlight for long term preservation.
