This viscosity of this crude is about the same as diesel. And I also know that there is some paraffin content, when we ship our oil I looked in the bottom of the tank and saw it. I am running it in it in a couple old indirect injected Diesel's I have around. I have a measuring stick that touches that paraffin in the bottom of the tank. I haven't noticed any abrasiveness or sand.Both trucks that I run it in do have pretty hearty filter systems on them from the factory.
