    I am currently looking into the Millettia Pinnata (Diesel Tree). The seeds can be cold pressed and the resulting oil extracted is suppost to be able to be used in diesel engines with no further processing only filtering. Time will tell.

    I have been running mostly B-100 in my D3 for the last 6 odd years I've owned it, with no trouble at all.

    I suspect the blanket ban by some manufacturers on biodiesel is simply lack of certainty on composition and properties, especially that some biodiesel can break down under the pressures involved in modern common rail systems.

    They are going to start making Biodiesel in commercial quantities in Aus again. I wonder if Freedom Fuels will stock the B-20 again?
    That's great news. We haven't been able to get decent quantities for ages - well, since they shut down last time actually. Will be onto this to see when the supply chain can start delivering it in decent quantities.

    Like John said, we are cautious about allowing bio diesel to be used in our equipment due to the lack of any certainty of how it was produced or stored. With the Barnawartha plant coming back on line, we'll be able to supply to our customers directly again.

    I'm glad to hear your customers are still keen to use bio, despite all the scare campaigns and ignorance on the matter.

    IME, depending on your processing...

    you lose between 10 and 20% of your initial quantity of oil Depending on how you process depends on how much waste you have. adding in the methanol you can actually wind up with more L of fuel than L of oil you started with (but still less than your total of methanoil and WVO.)

    Guess who learnt that the hard way when a process batch overfilled a 44.

    My weigh in on the Bio in unit or common rail diesels.

    If the bio is perfect then its good to go, however as the bio degrades the heat and pressure in the fuel system (particularly the injectors) is high enough to break down the bio so it no longer lubricates properly.

    That said, I run old school diesels, I process my fuel as WVO, filter it, dewater it mix it with a little diesel to keep it liquidy enough to get through the LP lines then pump it to exhaust via the engine.

    There is a growing call for it on large Federally funded projects because it meets one of their ‘green’ KPI’s. Biodiesel is one of the easiest ways to tick that box. 😉

    Interesting.
    The Caltex servos from Tamworth through the New England used to stock I think 10% bio?
    Anyone remember exactly?
    I used it when I could get it in the Defender and Patrol (Tdi & TD42T) as the engines seemed smother and appeared to get better mileage?

    Depends on the feedstock, canola being one of the better, though I used a lot of cottonseed.
    Then there's the 'quality' of your esterification process, and of course, washing / drying/storing, - it's hydroscopic.

    Despite that, my Jap-import Mazda 4WD van (Bongo) devoured a LOT of experimental litres of diverse quality.. only hassle was a clogged fuel filter - bio WILL shift a lot of **** off the tank walls and lines - which only happened once.

    But if any of the flexible fuel lines and seals etc are made from rubber... bio will eventually soften and leak. The 'fix' is VITON based material, also to be used in IP seals and 'O' rings. Has been standard in European engines for a long time now.

    The other thing of interest is cetane rating. Some light reading on the matter... Biofuels - Types of Biofuels - Biodiesel
