You can not make biodiesel using only 10% Methanol. A chemical reaction requires things to be just right, which requires a little more then is actually needed no get the mixtures where they need to be. Also the amount of Glycerin in your triglyceride is often more then 10% of the entire thing. The only result you will get with 10% methanol is partial Biodiesel, partial monoglycerides, partial diglycerides, and partial base oil. Then you are reprocessing everything except the biodiesel and spending more time and money to get the same result. Your best bet is to set up a methanol recovery system if you are worried about the extra money involved in using the extra methanol.
Either way it just will not be complete the reaction if you don't use 20% methanol. I find that if you do your 20% calculations by weight instead of volume there are more consistent and better results. That normally is 22-23% methanol per a batch.
