I have just gained access to a monthly supply of 10s of thousands of gallons of used canola, vegetable and cooking oils. I'm know very little about bio-diesel. I'm not planning to make bio-diesel, I'm just going to sell it. Are there variables in the oils I should be aware of, or is it as simple as oil is oil? Any help with info. would be greatly appreciated. It's coming out of Australia, which I've heard might mean it's cleaner?
