Of course you should be concerned. Not all fuel is adequately winterized, and the next four weeks are a very dangerous period because some stations may still have fuel blended for October and you may get a January-like cold snap.I'm a new 2010 Jetta TDI owner. Should I be concerned about below freezing temps and diesel fuel?
After getting stranded with my '99 Beetle TDI once a year for the first three years, I always added fuel conditioner from November to mid March. I'm in central PA, but live in a very rural area. Temperatures when this would occur would typically be -5 to +15Â°F.I'm a new 2010 Jetta TDI owner. Should I be concerned about below freezing

I'd modify that a little: DO NOT use ether or any starting fluid EVER for ANY reason, period. It rarely starts the engine and can cause everything from the comparatively mild blown head gasket to cracked blocks, fires and general mayhem [g].Do NOT use either starting fluid unless it is an extreme emergency, it could blow a head gasket.

Chitty had it correct - the fuel filter is heated. Here's the text from my 2010 Jetta TDI manual:There is no fuel pre heater. I'm 99% sure. There is a heated fuel filter that is referred to in the sales literature but this is really just passive heating. In other words, the fuel return line is heated by the engine and pumps and by radiant heating. The return line passes through the fuel filter and that warms it. This has been the case for a long time. So if the fuel is close to gelling the fuel filter won't get clogged. After a long drive the return line fuel also warms up the fuel in the fuel tank.
If you're really concerned then you can add an electric coolant heater. You tap the coolant line to install it and plug it into an electrical outlet to use it.
I had to look this up, according to wikipedia regular diesel could get as high as 5oF, winterized fuel should handle -20oF. 32oF is freezing. 5oF is -15oC.
Which model do you have and do you have any pictures of it installed? One complaint I've heard from people who installed the Frost Heater is that it always seems to get in the way of components when maintenance comes up.I'm from Alberta Canada eh, and it's cold as....a polar bears toe nails up here lol!! I had a hard time starting my mkv the first winter and i tried many different stations but still no dice. It gets to -35c here on a rough month up here so it's chilly for sure. I was having to sit and wait for long periods of time waiting for the glow plugs to heat and even then it was not always on the first time ..i was getting a lil nervous !! Soo i started using Power Service Diesel Kleen when it gets -5C and wow it's amazing ! My car started like amazing and it just sounded better starting up as well. Well this was all great and dandy until it hit -15c then i was having that same problem soo i got one of these oil pan heaters http://www.dieselproducts.com/cgi-bin/online/storepro.php
Mine was like 90 bucks with installation from my mechanic who was the guy to recommend me this. I got a timer on my my plug so it turns on like 40 mins before i go to work and i just unplug it when i get to my car. It is truly shocking how nice my car start now . I have no fear that my car won't start now even in the coldest of days lol bring it on mother nature!!
