This is the answer.
So as it turns out, a heater fuel is much more pump common than I had anticipated. Ultra low sulfur diesel. This stuff (excuse the dirty pump lable) You can find this at MANY circle K, and other gas stations, but this is what you're looking for. It's actually cleaner than 1K Kerosene, as 1K has 40ppm sulfur. I've tested this, been using it in my dynaheat dh-2300 heater and it works perfectly. I dump some scent/water kero fuel treatment in it when I fill up my 5 gallon can. This is a much better solution than 20$/gallon 1K from big box stores. I'll add some links below supporting this claim.
