Way, way back when I helped oversee a fuel farm, one of the gents from Chevron informed me that Jet A, kerosene, home heating oil, over the road and offroad diesel all came from the same tank at the supplier. The difference was the additives added at the manifold as it was pumped into the trucks. For example diesel would have dyes and lubricants added while Jet A was basically pure.
We ran home heating oil for years with no problems. Ran it in the vehicles too, just added a bit of marvel mystery oil at each fillup.
