ours switches around late sept/oct to winter blend. And I think the A/D is actually part of the issue. my stock filter didn't have any garbage in it when I took it off, but the truck runs fine after, so the pleats on the filter might have waxed over.
Does diesel fuel gel these days

I'm assuming that is a GMT900 thing then. 800s do not have that feature. I'm actually glad I don't have it because there's several reasons for low rail pressure other than a plugged filter.
I forgot that I had summer fuel in my 82 (my tank was filled in June). It dropped below 20F and gelled up while I drove. Had to coast to a parking lot. 
D'oh!
If you are filling regularly, the local fuel should be blended for the temperature. Some additive never hurts, though.

Yeah, I would probably get super annoyed with that. It needs an undo that resets the life back to whatever percent it was before. I've set low rail codes a couple times due to weak CP3. But really, once I dialed the tune in, I don't have it happen, so probably a livable "feature".
Just remember the 911 stuff is really hard on the truck, so try to avoid it as much as possible. I had 50/50 jell up on me a few weeks ago. I always travel with at least one extra set of filters in the truck. Really should have 2 sets since you can count on fragging out the 1st set if you still have bad fuel in the truck.
