A delivery today has got me a bit worried......he's running a 50/50 blend and his bulk storage tank has a scummy, foamy film floating on top of the mix. A sample shows the fuel underneath is perfectly clear, but it doesn't look too good. Any suggestions what this might be? (Apart from foamy scum, of course!)

Is this bio that you have produced or from another supplier ?

Ohh its a technical query.
I thought foamy scum was a new way of insulting someone!

It's my produce. I use KOH, never accept anything other than a perfect 10/90 test, mist wash until water is clear, bubble dry, then eco. I'm wondering if it's temperature related, although it's not particularly cold over here; we have had no frosts and it's presently 10c. I can't see any problems with other stock in my shed. Could it be 'diesel bug'?

Froth/foam on top can sometimes be excess soap, but with your washing process this should not be the case.

Highly unlikely, diesel bug will block a fuel filter in very short time and replacing an element makes no difference unless the whole fuel system is completely cleaned at the same time, and I mean the WHOLE system.
