When making home brew B-100 do you have to make sure that the oils you use are the same in a batch? or can they be mixed? what if you don't know they are mixed when you get it from the source?

 

when you make your fuel you have to do a titration to know how much catylist to add (sodium hydroxide). So it doesnt matter what is in there for oil, mix virgin oil with Mc Donalds and it will be fine cause you need to do a titration for whats in the processor every time.

even oils from the same place may vary with each batch you make. The titration will tell you what to do.

 

And it gets even stranger. If you store your oil in a big container (like I do) the oil from the top will titrate differently than the oil from the bottom. Make sure the oil in the processor has been homogenized by leaving it to circulate for 10 to 15 minutes before titration.
