Now I'm thinking about cross breeding sap suckers with kangaroos; so they
could extract the sap and store it in a pouch.

Surely an samll quantity can wok as co solvent or surfactanat making
the biofuel blend is made possible.

Your relevant secret information , making here open show Ben has not
only have very good practical knowledge , but open minded person just like
most of the SOUTH AMERICAN , AS WELL AS LATIN AMERICAN TOO.
ETHANOL DEHYRATION IS VERY IMPORTANT TECHNICAL PROBLEMS ,
I am sure your secret method for biofuel the same is more important not
only for biodiesel , and also for fuel too as these are abundent.
Ben can you give me some idea about what the pocentage of bio iol now
possible to mix with diesel.
what is the method ,or best process that can ,to make more bio oil to be
used for this blend
With kind regards
