Hey thanks Tony, we are on the same wavelength, l made 200 litres last week, and after letting it settle for 24 hrs l ran it through a super cheap autos $1.99 fuel filter before filling up my tank with it.

Have used half a tank getting round town, runs great, got 200litre drums from a salvage joint on gillam drive armadale five for $60 bucks, and sodium hydroxide from mazzegas at cost plus...$11.50 for 2.5 kilos works out at 23 cents a litre with free chipper oil

l'm impressed thanks for putting my mind at ease about my engine....Im not washing my biodiesel, looks so clean and pure as it is, and thought in this forum seems split on whether it is really necessary?
