Below 15 degrees F, wax crystals (Paraffin) begin to form in diesel fuel, K-1 has lower lubricity properties and no road tax. You can mix K-1 in diesel but you cannot use it straight. Kerosene has less btu's than diesel and adding a common lubricant to Kerosene usually decreases its ignition quality.
Kerosene is too thin to work well as an engine fuel.

Heating oil (#2 oil) is dyed diesel fuel with the only difference being the dye. They do cut it with #1 to winterize it if your tank sits outside, just like over the road diesel. They dye it so that DOT can identify it if they happen to pull you over and dip the tank. You do not pay road taxes on dyed heating oil, which is why they dye it. I actually use dyed B-20 for home heating because it makes me feel like I'm helping the environment.

The OP asked about K-1 in the title ...... and then asked about heating oil. After reading up on it, it seems to me that K-1 (#1 heating oil?) is different from #2 heating oil. The difference being that K-1 has a higher kerosene content (different from #2 heating oil AND diesel fuel).

In a pinch I was extremely low on fuel and put about 7 gallons of K-1 in my tank then drove straight to town and put diesel in it.
No ill effects yet.

The way I look at it, the lighter fuel like Jet have no lubricity, the heavier oil has lubricity but home heating oil is to thick.

Welp. I'm going to pump out a guys oil tank, mix it with my homemade biodiesel and give her a go. I've been burning a JP-8/Biodiesel blend for a while and its the most beautiful fuel I've ever seen if I do say so myself.
