Does svo have to be filtered before used as fuel for a diesel car? - buy waste vegetable oil

I have an old Mercedes, turned to run on vegetable oil, but the process of the oil filter takes a few weeks. Meanwhile, asked if I could buy vegetable oil, and it directly in my tank. Thank you for your help.
