At a whim some time back we mixed a high ratio of methanol to biodiesel. The result was a completely homogenous fuel some days later.
If memory serves, the ratio was 1:1. A bit more than a simple enhancement.

Actually the methanol doesn't mix that well with the biodiesel. IPA (Isopropyl Alcohol) does and seems to have a beneficial effect at quite low concentrations 2% even. IPA isn't cheap here, 95% ethanol, even at 10% is attractive since that is what is sold as metholated spirits. Tony clogged up again this morning-looked like mud- really must get across the need to add the biocide.(sorry Kieth) --- In [EMAIL PROTECTED], Keith Addison <[EMAIL PROTECTED]> wrote: > G'day Steven > > >G'day Keith & Camillo > >Thanks for the information, leads and suggestions.Can I please ask, what does > >DIYS IMHO stand for....something about do it yourself? > > "Do-it-yourselfers, in my humble opinion". > > >I presume when you mention about using an alcohol to lower cloud point, > >methanol could be as easily used, but is not the fuel of choice because of its > >origin. > > Yes, I guess that's right.
