Away for the weekend, on Thursday I had no fuel left and was going to do a batch of veg.
Started to filter it, the jcloth fell to bits so decided to do a batch of bio.
Sieved 40 litres of poor oil, made up to 105 with good stuff. Up to temp then left for a wee half hour.
Meanwhile, mixed 20 litres methanol with 800g KoH (the 65 litres normally titrated at 0.2 to 0.3).
Drained off 5 litres, added methoxide and let circulate for 2 hours then settled for an hour.
Done a 10/90 and had 1ml of dropout. I've put that in the wifes CRD before and this was for the Audi so didnt bother with a second stage.
Started water washing, after around 5 x 20 litres, there was no visible soap between the water and the bio so done 1 more wash then dried overnight. The water washings done with a hose connection (takes about 5 mins to add 20 litres), not a mist head.
Switched off at 7 am and left to settle till half 1. Drained about a litre (it went clear) then pumped through a 10 micron into the car.
