“Often this is remedied with glow plugs, which are heated by the battery and help warm up the fuel so it can vaporize.”
In trucks in cold climats they sell #1 diesel instead of #2 which doesn’t gell and has a lower flash point.
If you go into cold climate with a load of #2 all you have to do is add 1 quart of ATF per 50 gallons of #2 and you have #1.
THAT’S GOOD INFO!..............
