Ughh...
All through winter we ran on b100 - no additives or nuffin.
Its now May, and we get to limp home on the second filter due to cloud point issues!
Id been keeping a sample in the back yard, but got lazy at looking.
Oh well - at least the 2nd filter seems to last as long as the first (so gets you back however far you've managed to get!)
That aside, im starting to wonder if ill ever be able to use this ever growing mountain of tallow. I think maybe we will have to go on a driving holiday in July or something!
