Booyah, around these necks of the woods, winter fuel is the ONLY thing you can get, with a -20 pour point.
I'll check on the grid heater.
I opened the petcock on the bottom of the fuel filter/separator and, guess what? Water poured out. PLUS, some white chunks. I think the filter change is DEFINITELY in order. After I did that (plus jump starting), Brunhilde fired right up. Today, she gave me no grief at all.
