If your not running any form of winter diesel, just straight #2 your fuel filter will clog. Been there with an old VW Diesel. A couple of disclaimers here though. If your running before it get's cold you'll be OK as long as you don't shut down as your heating the fuel by re-circulating it. Most suppliers will treat their fuel without your knowing it, I'm sure you've noticed fuel mileage drop in winter about the same time the prices increase

. Even if it clogs it's not terminal, treat the fuel, change the element and drive on.
IMHO we should be treating the fuel any way, winter and summer, and as you said that will in itself provide protection.
