Kerosone fuel for a jet heater - not that easy to find these days

I have 30 year 100K jet heater that I use on occasion. The last time I filled my tank was easily 20 years ago so it doesn't get used often but sometimes its quite handy. I went to use my snowblower yesterday and found that the impeller was frozen solid to the drum in pretty big lump of clear ice. I tried chipping it but at around zero degrees I wasn't in the mood for a long effort. I tilted the snowblower chute up and got out my jet heater and aimed in in the chute. About minutes later it was melted out and I was out snowblowing. The bummer is 20 years ago there were a couple of places in the area that sold kerosene at the pump but no longer. The local Irving gas station used sell 5 gallon pails for truckers to dose their fuel if it got suddenly cold but they don't carry it anymore. If I want a 100 gallon minimum and have a bulk tank I can special order it but not practical for my usage. Right now my only option seems to be a special order 5 gallon can from Ace Hardware at around $10 a gallon. Plenty of places sell the equipment but looks like few sell the fuel.

So any suggestions I am overlooking for finding and buying K-1? I have heard that winter diesel I pretty close to kerosene and now that its ultra low sulfur do I just run winter diesel?

Searching around after I posted this I see a lot of references to using Jet A and many folks are using #1 Diesel. My guess is Jet A and K1 may be straight run distillations so they will be more stable if the stuff sits in the heater for years. My guess is regular diesel is probably at least partially cracked so it may have shorter shelf life although rarely do I hear about shelf life issues with Diesel.

I wish it was so simple. The local gas stations are chains and they do not have Kerosene pumps and the same with the heating oil dealers.They will do bulk deliveries but that is it. It strange as lot of folks used to use kerosuns.
