The car has 197k on it and I've put about 4k miles on it since I got it, most of it on B99.
I will try power service today. I certainly hope it is that simple.

Cold Weather Management
Unlike gasoline, both petroleum diesel and biodiesel can gel at cold temperatures. If the fuel begins to gel, it can cause increased stress on fuel pumps and fuel injection systems. It can also clog filters or eventually become too thick to pump from the fuel tank to the engine. B99 gels at a higher temperature than conventional diesel fuel. Most B99 begins to thicken (cloud) at around 35°F. To prevent cold flow issues, some users switch from B99 to a blend of B50 in cold weather (below 35°F). B50 provides adequate dilution to prevent cold weather gelling. Other options for using B99 in cold weather include keeping vehicles in a heated garage, using fuel system heaters, or using winterized biodiesel (biodiesel with cold flow additives).
