Yep, #2,#1, kerosene, in that order. Shorter hydrocarbon molecular chain so less btu.
You can store it in a SEALED metal container for a year no problem. As long as it's not biofuel kerosene- if so add some dead bug juice. All fuels have heavies and lites- the lites evaporate through plastic, rubber, or any hydrocarbon (hmm same molecular material) container.
It's not quite highly filtered diesel, more like more refined diesel fuel.
If you run diesel fuel through your home brew distillery, you'll get out mostly kerosene, some gasoline, and a bit of propane& butane.
And yes definatley add lube if you choose to run it in your truck, less carbons = less lubricant than real diesel, maybe more than ulsd, but err on the side of caution. Good for emission testing when probe or snap test is used.
