I know there are many variables, however, what is the typically gel point and CFPP of commercially made B99? What is a good additive to run in winter with B99? I've been using Stanadyne Lubricity Formula when I have to run regular diesel (on a road trip, etc.) and I have some left over Performance Formula. The Performance Formula claims to lower the gel point 40*F from whatever it was untreated. How effective are fuel additives for regular diesel on B99? Thanks for the help.
