generally which is more expensive, longer shelf life & useage?
thanx
Kerosene is cheaper, but smells more and there are different grades.
1 Red dyed kerosene- is the cheapest but has the most smell, and gums up wicks faster. I would recommend it for outdoor use, especially if anyone in the house has respiratory issues.
2 K-1 kerosene- still pretty cheap but much less smell, pretty good for indoor usage. If you have no respiratory issues use this.
3. Synthetic Kerosene- the best bang for the buck for anyone with respiratory issues or those who are very sensitive to odors.
4. Lamp oil- the most expensive, but it smells kinda like you were frying something and supposedly puts out the most light.
The shelf life on all these products is so long in a sealed container that I wouldn't worry about it. If no water gets in them they will last longer than you will. They also make scent for kerosene that will help with the odor sensitive, but not with respiratory issues. A gallon of kerosene can last for 200 hours in a large hurricane lantern, if you don't spill any.
