Kerosene Space Heater

It is usable as is. But I'm sure you do not like the smell.

The best answer (I think) is to mix a blend of biodiesel with kerosene. Start at 50% -50% and labor is down, or work more, depending on what your needs are.

If you're in the cold and do not want biodiesel "freezing" add more kerosene.

Looking to save money on fuel, add more biodiesel.

Experiment to find the best biodiesel / kerosene mix for your own situation.

Notice all the space heating with kerosene is not conducive to human health or cohabitation! Any-one who does not head the warnings is just setting themselves up for an extremely reduced life expectancy! All the oil lamp to heat the exact same amount of impact on the human population in an unventilated scenario!

kerosene is cheaper than biodiesel

A couple of items that you can use in kerosene heaters. I would try just to see (outside).
This is one of the following links:

Biodiesel is comparable to No. 2 fuel oil, so it may or may not work in a kerosene heater. Reason for not working is that it may be too thick for heating. If the manual indicates that the device operates on fuel oil # 2, then it will work very well.
