What's the difference between winter and summer fuel?

Home heating oil is not all the same either, there is stove and furnace.
I know some trucking companies with their own fuel that switch to clear stove around Nov 1 in the northern climate.

 

That's true, most are just marketing monikers, Stove oil is #1, while furnace oil is #2.

I buy #1 stove oil here from a wholesaler for $6 a gallon to blend with polished used oil for the pole barn heater because it is kerosene. This heater runs better with that blend than it does with diesel as a blending agent. The guy who owns the place said he calls it stove oil out of habit because of two of his long time customers still use it as stove oil for their stoves (do you know they still make kerosene ranges?) The same goes for the old man who orders 1000 gallons of Bunker A oil a month for his business, his treatment furnaces use non-heating burners and can't use anything else. He just sells him #4 oil and writes on the sales slip Bunker A oil to appease him.

 

You can buy straight #1 at the townpumps in montana

 

Most fuel stops in the Dakotas and much of Minnesota have #1 available during the winter as well.

 

Better than 6 oil, that's for sure.

I've hauled quite a bit of 4 oil to port terminals, they told me it would be burned as bunker fuel once the ships got out into international waters.

 

Winter gas is more volatile and evaporates more quickly, so it is ideal for it is used in the colder air of winter.

 

The alcohol [or other antifreezes or water separator] content is higher in winter gas.
