Straight VO should not be used below 160 F.
B100 gels at 40+ F.
I don't know the properties of diesel blended fuel let alone B100/SVO blend.

I don't think you can run B100 in the winter without a heated fuel system. I understand that winter is a relative term. It is currently 8 F here, probably not 8 F there.

So, do it.
Please keep notes and let us know how it goes.
