Whoa, that's way, way, way too much KaOH. A really good way to make soap if you have water present.
Methanol is usually 22% by total volume of oil and 4 grams lye per liter of new oil oil, or 4 grams of lye PLUS 1 gram per ml added in a titration.
My last batch of Bio was 120 L (little over 30 gallons) only used 23L of methanol (IIRC) and 600 grams of NaOH (little over a pound).
150F is awful close to vaporizing methanol, 130F is usually considered a better reaction temperature.
