First, thank you for all the great info to my earlier question, but forgiving my ignorance; what is the difference between SVO (straight vegetable oil) and WVO?

Waste Veg Oil is veg oil that's already been used (in a deep fat fryer, for example); SVO is veg oil that hasn't been converted to biodiesel or, can also be virgin veg oil that hasn't been used first for cooking.

Thank you very much, you have saved me a lot of time and trouble with the information you have given.

Welcome to the forum and hope you learn a lot more here. It was a short time ago that I learned the answer to the question you asked . I am not trying to be mean, this is just some friendly advice. I found it by typing wvo svo into the google search engine. I tried it again just now and the answer was in the fourth entry returned.

You will get a lot more from this forum if you put forth some effort.
