Emergenceis, lets say, occur only every 5 years. Or 10.

So, you want to store a bunch of kerosene for that
eventual emergency. But doesn't kerosene "go bad"
after a while?

What can you do so as to keep the kerosene "good"
for a LONG time?

Also, what do YOU do for keeping around the ability

for eg a week or so?

Thanks!

I believe K-1 kerosene stores better without treatment than #2 diesel,
and #2 diesel does pretty well by itself. Keeping it sealed and water
free is the main way to ensure long storage life. A biocide is helpful
if there may be some moisture in the fuel that could promote
algae/bacteria growth. Power Service Bio Kleen (not to be confused with
their Diesel Kleen) is a strong biocide that can give you that extra
protection. The cetane boost and anti-gel additives that are available
aren't relevant to kerosene or to basic heaters.
