Diesel Kleen White comes fall & winter.
And when it gets around 20 below zero or colder, isopropyl alcohol in addition to the Diesel Kleen White.
You may call me Doctor Overkill, that's okay, but I haven't had any fuel gel up or fuel lines freeze yet in Minnesota winters.
No engine issues in 300K+ miles. Other issues, yes, but never engine issues.
Adding any alcohol to a Bosch HPFP based Common Rail diesel is death to the High Pressure Fuel Pump. Anything that is operating at 1600 to 2000 bar pressure can not afford loss of lubricity to the fuel on American standard D2 diesel fuel. Don't do it, if you own a newer diesel truck or VW or Audi or Porsche Cayenne TDI.
