Hi Adam
Good to hear of someone using bio on a regular basis. B20 is 20% bio
diesel and 80% normal diesel which is fine for the rubber components.
The problem comes with higher percentages and particularly using B100
which is what I'm looking to do. (well, will end up running between
B50-B100 depending on whats in the tank when I make up a batch of
Bio-Diesel)
The Methanol or Ethanol is used within the manufacture of the
Bio-Diesel. You take 87% Veg oil and mix it with 12% Ethanol along with
a 1% catalyst for the transesterification process which gives you
Bio-Diesel and a by product of Glycerine which can be used for soap.
I'm building a little bio-diesel maker so that I can make it on the road
during the around the world journey!
Thanks
Mike

I've been using soy oil based bio diesel for 4 years now, in
concentrations
of 10% or 5%. Ordered 1,500 gallons of B20 or 20% for this spring. I
haven't
had any degradation of rubber fuel related parts as of yet. I have run
it
100% in a little Oliver 77 diesel tractor no problem but the exhaust
smells
a bit different. Gained about 8 hp on the 36 hp tractor at 100% soy
diesel
in dino tests. I wasn't aware that they make bio diesel out of methanol.
But
have heard of the ethanol version being tested around here. In Minnesota
there was a bill to mandate 2% bio diesel by 2005 but I don't know what
became of it. Thanks, Adam Suess
