Kerosene reduces lubricity and #1 diesel is already winterized. Unless you're driving from Texas to Minnesota on one tank of fuel in the middle of winter, #1 diesel doesn't need any additional anti-gel.

Diesel does not need any additives as long as you use #1 in the winter months to prevent gelling. Neither #1 or #2 needs any help in lubricity. ULSD became the only on-road fuel sold since 2006 (no matter the pump label), if there was a problem with it there would have been a sudden mass of pump failures within the first 2 years.
The fact we are nearly 5 years into it with 99% of the worlds diesels using straight diesel from the pump means the entire "lubricity" issue was, from the start, purely a myth to sell useless snake oil off the shelves. Just as it was in the early 90's with LSD.
