ULSD is already causing probs in Injection Pumps
Read the other thread. It is very close to this one, but has some good info not covered here.
This what you need to do, IMHO only!!
1 Add some transmission-sealer-in-a-bottle to the fuel filter and the tank. Worked like a charm for me.
2 Make sure you have some biodiesel in the tank at all times.
Has continued to work for me since doing above.
3 Keep a bottle of transmission-sealer-in-a-bottle in your trunk for when you cannot get biodiesel.
For those of you asking about adding vegetable oil, use canola. It has a lower cloud point and is the only vegetable oil recommended by
www.Elsbett.com in their SVO application. As little as 2% is enough to bring even the worst case diesel (kerosene #1) up to lubrication standards, supported by a university student's masters thesis. (I have got to learn to book mark these papers when I find them...)
