To the OP - K1 clear kerosene stores for a LONG time (years) in a steel can. Cooking will use up about a quart or two per week, depending on what you are cooking. Kerosene cooking stoves are kind of unusual, but work well if you find one.
There are different grades of kerosene, two of which are readily available. K1 is the clear kerosene sold for use in kerosene heaters, the price is kinda volatile so fill a couple of 5 gallon cans when it's cheap. It works well in all kerosene appliances and has much less odor. #1 fuel oil is yellow kerosene, this is also used as jet fuel and Arctic diesel fuel. Next is #2 diesel fuel which with the paraffin wax is still dissolved in the fuel. It will work in your kero lamps and cookstove, and is not recommended for kerosene heaters as if gives off an odor when burned in a kero heater. Lastly, #2 fuel oil or #2 diesel is not recommended in any kero lamp or stove. I have heard of folks using the #2 ULSD in kero stoves and lamps, not sure if this will work in a kero appliance.
Wick type kerosene lamps will run a long time. I have a Dietz "Lil' Wizard" with a one quart tank, on a low setting it will go for almost 48 hours on one filling.
