I'm building a plant to do 25 gallon batches of vegetable oil. 30 gallon drum to store up the oil, 55 gallon drum to mix 25 gallons oil with 5 gallons methanol. After mixing and draining the glycerin, I'll pump to a another 55 gallon for washing. Prior to washing I plan on heating up the reactor to about 140 and driving off the methanol. The point being the less free alcohol the better for rubber elements in the fuel system. So methanol recovery and washing is a good idea for Fords. Then use blended up to 50% with petro diesel, making B50. Ford only recommends B5, but B20 to B50 is ok. Also if you have a two tank system run B50 in one tank and petro diesel in the other. Switch to the petro diesel before shut down on the home stretch. This will flush out your pump and injectors so they don't bathe in the biodiesel which can be hard on rubber seals.
