..... and I've never been in a situation where I've had trouble with fuel gelling.

On occasion, when I've traveled to a location where I was concerned about the temperature, I've tossed in extra anti gel before, and during, the trip.

Here in Tidewater, VA., we rarely see extremely low temperatures, the last couple of weeks being the exception, with single digit lows expected again tonight. I did have the 89 Dodge-Cummins 4wd out the other day when it was in the teens due to the snow and ice but suffered no fuel issues. Normally, the vehicles are stored inside the shop and attached garage, where the temps are above freezing.

I know that there are summer and winter diesel blends, and there may be additional additives for cold weather locations, but what are the general temperatures at which point gelling becomes a real concern?
Apparently, +10 deg F is above the point of gelling for me locally.......

Thanks to dieselmania for the info on the two different types of treatment, although judging by his location, it's an academic point for him!
