invention of Kerosene and Paraffin (used for making candles), was
a major step forward in technology, impacting the everyday lives
of the entire population. Kerosene or K-1 is another by-product
of crude oil, however, this fuel is more refined than #2 oil, and
has a lower gel factor.
gel factor is very crucial to homes that have outside above ground
storage tanks. Kerosene will not thicken when the temperature falls
below freezing and #2 fuel oil will gel. Kerosene is most frequently
used by mobile homes and must be used for heating units manufactured
by Monitor and Toyotomi.
