Hi,
I'm new to this biodiesel lark, so please be gentle with me,
I made some biodiesel from old cooking oil and it didn't work out although the test batch did. The recipe from the book 'From The Fryer to The fuel Tank' says don't use anything other than pure etanol or methanol, my chemical supplier told me that Methelated Spririt is the same as ethanol, my test batch worked fine with it but my big batch (60ltr) turned to solid fat. I know that too much lye results in a solid mass, but could my problem be due to using Methelated Spirit?
Regards, Joby
