freezing point of kerosene?
 
Just winterizing the boat for the winter in Massachusetts. I left the stove fuel tank on board with it about 2/3 full of kerosene.

Does anyone know what the freezing point of it is, and do I need to be concerned about leaving it onboard?

Aircraft fuel is kerosene - suspect it''s not much of a freeze hazard.

No worries about kerosene - it won''t gel until it''s below minus 40F. It''s often added to diesel to keep it flowing in really cold areas.

Kerosene and heating oil have problems at about -50C flowing (personal experience) but the other factor is that often these fuels have water in them. The water freezes and falls to the bottom. Most problems I have had with kerosene were related to ice blocking the sump style drain or the filters in a rotary pump. I really really doubt if any of this applies to you, but I got a bit nostalgic with your post.

I am a pilot and have flown biz jets for years. Jetfuel is a pure cut of kerosene. Kerosene doesn''t freeze till it is in the -35''to-45''f range. There will be some crystalization of any water content in the fuel, but since you probably won''t be operating your stove in those temps, it won''t effect you.

Anyway, even if it did freeze it wouldn''t hurt anything because kerosene doesn''t expand when it freezes like water does. Water is one of the few few things that does this. That''s why ice floats. I think ammonia does it too, not much else does.

EXCELLENT point AJS! (most things contract when they freeze).
