From back in my ready mix concrete and rock quarry days (20 + years ago) we used to run a blend of 1/3rd kero and 2/3rds diesel, stopped the gelling problems. The Cats were the worst because they didn't have a fuel return to the tank like the Cummins or Detroit's. The returned fuel helped to warm the fuel. The Kubota's also have a fuel return. I still run some Kero in my BX in the winter.
