First a couple of questions Tom. If your titration numbers are correct, did you add 9.8 grams for EACH liter? That would be 196 grams KOH mixed with 1 gallon of Methanol.
How long did you mix for?

Can I just reheat to 145 deg and add approx 176-177 grams to make up the difference? Do I have to add methanol or can I use just enough to liquify the KOH like maybe a quart?

From what your discribing I'll bet you were off with the KOH. I would just add the remaining KOH after reheating and mix for 1 hour. This should work. Trying to add 150+ grams to a small amount of Methanol will create a TON of heat when it reacts.

I need to leave town for a week. Can I leave BD in separator without removing the KOH or Methanol or will it burn a hole in the steel drum?

How do you know when you have a bad batch? Has anyone used any of these dry wash systems out there? Also where do yall store your methanol? Outside? Will texas heat, heat the container enough to make it explode? what if i have a gas water heater in my garage?
