Winterized Diesel fuel is winterized with kerosene (#1 fuel oil). You can add your own but it comes already in winterized fuel.
Diesel's inject fuel very close to top dead center so no fuel combusts on the compression stroke. They are designed to withstand fuel burning at this time. Some diesels will run off gasoline just fine. Regular gas will do the same thing as adding kerosene, It will just do it with far less volume. Since gasoline burns far easier than diesel it will have the same effect as a cetane booster as far as burn characteristics. The problem with gasoline is it doesn't have the lubricity of diesel fuel and may end up wearing out your injection system(most notably your injector pump if you have one).

If your in a place with snow on the ground odds are the local pump is selling winterized #2 diesel. It has been cut with thinners that reduce the viscosity and the gelling point of the fuel. These lower the btu content of the fuel and eat into your mileage. Adding kerosene or gasoline will just reduce it more.
