i hate to answer my own question but ,i did a little research. some people heat it above 160 f and use it straight ,others mix it in various combinations with diesel fuel. i even found epa regulations on how much wholesalers can legally mix with low sulfur diesel fuel . we probably have had some in our tanks from time to time without knowing it. it does not have the glycerin that veggy oils have so you don't need methyl or lie to process it. it seems to be a filtering and viscosity issue.this deserves more research!
