From Caterpillar (and Cummins as well):

No additives needed. TWO exceptions.

If storing diesel fuel (make sure tank if full when storing to reduce condensation in the tank) for more than two months in the summer or three months in the winter, add a BIOCIDE. Available at any marine store, as diesel powered boats have the same issue.

If storing diesel you bought in the summer or fall into cold winter temperatures, add an ANTI-GEL. Available at any Walmart.

X-2, on the anti gel! I work for a trucking company all my working life and the only thing that was put in the diesel tanks was anti gel during late fall thru winter.
