    Re: My first wash. AARGGHH

    Hi John, Didn't Neutral actually say that for every 2 litres of soap produced it takes 1 litre of biodiesel with it into the glycerol layer.

    Re: The chemistry of the glycerol (and soap) phase

    Would it be possible for Mark and Tilly to respond to this post in a reasonably way, Tony can interject also if he wants.

    OK, so I've read most of the important info on here but there are some wee...

    Re: Confusing problem with my biodiesel

    More information here, graphs from mathmatical models that also don't seem to agree with Mark about the mono,Di and Tri distribution.

    Re: Confusing problem with my biodiesel

    Hi Mark, not questioning your chemical knowledge but I don't think that statement is true. I've done dozens of tests adding varying excess amounts of KOH to my process and used a range of...

    Re: Confusing problem with my biodiesel

    I think Wesley is correct, what you are describing are monoglycerides left in your bio. They emulsify very easily with water and are soluble in methanol (so invisible to the 3/27 test) just use a...

    Re: Foolproof Room Temperature (FRT) Biodiesel

    Thanks Mark, I now understand. Would using other anhydrous catalysts like ASM (Anhydrous Sodium Methylate) also give rise to no water from ffa neutralisation.

    Re: Fat fail

    Hi Johnnojack, one problem with a gloopy batch is that continuous fiddling around with it is very confusing if nothing works, leaving you with more problems. As Tilly says doing trails on small...

    Hi 3DB, been running several Peugeot 806 2.0 HDI's on 100% bio for many years. Those engines seem to love it.

    Calling Tony from west Oz

    Tony, I tried to send you a PM about water/methanol injection but the forum says you have exceeded your PM storage and you need to clear some out!

    I've saved it for when you have space for me.

    Re: Musso Fuel Gauge stuck at 3/4 tank

    I intended to do the test with the low fuel light about 10 times, each with about 10 litres of fuel. Surely even though the level where the light comes on isn't accurate, over 10 times the error...

    Re: Musso Fuel Gauge stuck at 3/4 tank

    I've noticed the fuel gauge on my 2007 Ssangyong Rexton isn't very accurate. It seems to have a 'delayed reading' up to half full.

    I'm trying to get some economy figures at the moment with and...

    There is a member of this forum that sometimes posts in what I can only describe is a very demeaning, belittling and impolite tone.

    Re: Wanted: Centrifuge Filter

    Cheers Ben. It wasn't meant to be a serious option for you as it is in the UK, but just to give you an idea.

    Re: Dewatering WVO with petrol.

    I can't answer all of your questions Tony as I've never ran on WVO. I assume the SB is as accurate with oil as it is for bio. The sample size of 30mls (variable) is added to 10mls of anhydrous...
