Biodiesel Winter Additives!

Getting rid of those Winter Blues While Runny Biodiesel or even #2 Diesel in cold Temps!

I run anywhere from B20 up to B100 even in the winter without an issue, because I remember to use winter additives.  Here is Oregon the fuel companies like charging for additives, but offer very little to any for winter conditions.  There have been whole newspaper articles written on how biodiesel was killing all the diesel powered cars in the winter, was the biodiesels fault.  The fuel companies were not adding winter additive and even straight #2 diesel will gel when temps drop.

Stages of the effects of low temps on Diesel:

Level 1 – “Cold Filter Plug Point”
This is the point at which there is enough solid waxes bound togather in the diesel to be caught by the filters. There not be enough for you to really “see” yet, but they are being trapped by the filter. If the fuel remains this temprature long enough and if enough fuel flows through the filter, it will become plugged, even though the fuel may look “clear”.
As the fuel gets colder and colder, more of these waxes bond together to form bigger and bigger “polymer bonds” of waxes.

Level 2 – “Cloud point”
This is the point at which the fuel looks “Cloudy” to the “naked” eye. There is enough of these polymer bonded waxes to form large enough chains to be visible. It will abviously stop up filters here.

Level 3 – “Gel Point”
This is the point at which there are is an “infinite polymer network”. The point at which the fuel starts to be a solid or semi-solid due to these polymer bonds. The fuel will not flow at this point.

Cold filter plug point/Cloud point is anywhere from 20*F – 40*F depending on water and contaminates in your fuel.

Gel point is around +5* give or take a few degree.

Biodiesels are more prone to Cold filter plug point/cloud point/gel point. They can plug faster, they absorb water more redably.
