Also what does the fuel look like with too much lye and what does it look like with not enough lye.
"chilling" AFTER mixing actually helps the settling process. I use a mix temp of about 145 deg, and it mixes instantly, and the reaction is finished within 30 min.
If you use too much Lye you will get "foam" on top of the bio, this is soap.
If you use too little Lye you will not get a complete reaction, and the mix looks kind of "mocha" color, and will not separate
