stove oil vs. furnace oil

For my snow blower tractor, I have never gone more than a 50/50 blend #2/#1. It has started and ran fine @ -30*F in southern MN. Sitting for a couple weeks would classify it as stationary tank. I have even started the semi @ -10 on straight #2 fuel. While most think they have gelled fuel, more times than not, through natural condensation of the seasons, there is water contamination of the fuel caught by the filter and they have a "frozen" supply of fuel, not a "gelled" supply of fuel.

In other parts of the country the supplier might have the furnace blends. My supplier has only 3 grades to deliver. #2 hi sulpher, #2 and #1 low sulpher. I haven't asked but I honestly even think it's only 1 and 2 low sulpher only. The taxex and dye is what seperates them.

#2 will give you more heat at a cheaper price, however since you mention mobile home - don't even think about it.

First off, you have an outside tank, so you need the flowability of the #1 Sove fuel. Secondly, if you have a smaller mobile home (vs. a double-wide) your nozzle in your funace is probably going to be a .50 or .60 gallon nozzle. (Perhaps in Canada they use different numbers?) Anyways that means that your furnace can burn .5 or .6 gallons of fuel per hour with that nozzle. All fuel nozzles orfices are tiny, but in comparison those are extremely small and they have a tendency to plug up much faster than those in a bigger furnace. The #1, while not necessarily cleaner, is for lack of a better term, more pure. It won't plug your nozzles nearly as fast just because it is thinner basically.

So no. Your supplier isn't trying to make an extra dime on you. He actually knows what he's talking about.
