Dear Jan,
If I understand correctly somethingcan be
wrong with the pH measurementswhich Andrew made and
reported.
The pH can only be measured in an aqueous system
and not in an oil/fatty phase
Hello,
I'vemade and washed 4 test batches from
different wvo oil sources andhave comeup with some quite clear,
light amber colored BD but it all seems to test out at pH 6 + or -. This seems a
bit low. Any ideas about what would cause a consistent low reading like
this?

the biodiesel. Is this right, Bob ?
