From what I've learned, ULSD does have a higher gel temperature than LSD. The other problem is winter blending. #1 ULSD that is 15 ppm or less is much more rare than #2 ULSD, so some suppliers and certain areas are having a harder time getting enough #1 to blend into highway diesel to effectively make a winter blend. Since the EPA requires less than 15 ppm, if they don't have enough #1 that fits the bill, they have to skimp out on it. So some of use are finding summer fuel at stations during the dead of winter.
The other issue is additive packages used for years on LSD aren't as effective on ULSD. So suppliers have to reformulate, and apparently for some it's a very slow learning curve.
Anyway, that's the two main issues that I've read about here and there regarding ULSD in the winter. Maybe there's more to it? I dunno, it's just what I've found so far in my limited research.
On a personal note, this year's mileage and last year's winter mileage really hasn't changed much from the summer. I'm used to a 1-2 mpg drop during the winter months, but it hasn't really happened much in the past 2 years. Not having enough #1 diesel blended into the fuel would explain it.

I agree with Curtis there on what he said. Yeh this new fuel doesnt have the flowing capabilities in the cold the old did. I had never anything gell untill two years ago when the changeover was made. An we got to realize these fuel filters are way more restrictive on these trucks then they were before. BTW pretty fast truck there Curtis.
