"First of all it is not the ONLY thing available in a town. Second is if you are going to be lazy and put it in your truck then keep on using it and don't switch back and forth from B20 to B5 or straight diesel as this will cause the most problems. Second is to use a fuel stabilizer in every tank of biodiesel though at reduced concentrations as compared to having the vehicle stored."
Wintersun - This is a fine solution if you do nothing except drive around one city. But keep in mind many of us travel across many states so this flat won't work. Especially in some western states where there may only be one or two choices for fuel when you pull of the highway after driving all day. I have run some of all the different blends this summer - could not be avoided.
