I'm a big fan of the Wonder Whiz myself.

Prevents gelling in winter, quiets the injectors. Helps mileage a tiny tiny bit. It's not enough to offset the cost, but I like the extra lubricity it provides.

In my 35Gal tank, I use 12oz PS and 4oz MMO mix.

PS diesel Kleen - White for winter, Silver for summer.
