B100 runs great during the summer, however, you might want to do a blend in the winter. That or you can add antigel to your tank or ask if it is already been added at the fuel station. There's lots of info out there about winter biodiesel, so I won't include it here. Also, I can't prove that it was related the switch to B100, but soon after I switched over, the main gasket in the fuel injector pump blew and I had to have it rebuilt. However, it was rebuilt with bio compatible seals, so no problems now. I never had any problems with my return lines. Other than that possible problem, I haven't had any issues running B100 or B20 in it and it smells great. You might want to get the injection timing checked out if it smokes a WHOLE lot. However, that's not area of speciality so hopefully someone else can make a better recommendation on that.
