So i have been using all different sorts of WMO in a variety of diesels i have owned over the years with great results. I have a pretty good filter station going on, and ultimately end up at 2 microns (per the final filter, never done any labwork).
Anyways.....
I have the opportunity to get a neighboring farmers 400 brl tank. It is about 1/3 of the way full with crude oil. I dont know much about it (sweet,sour,etc).

1. Is it useable in a waste oil heater?
2. Is it useable in a 6.2 or other low pressure mechanical diesel?
3. If no to both, what about if i cut it with off road (at what percent?)
4. If not useable for anything, how can i safely burn it during large party bonfires?

Can someone give me a down and dirty on it? Im not wanting to risk my wmo heater, or any engine. But if i can separate it, filter it, and cut it, ill do it.
