E350 Bluetec and cold winter
I'm guessing that the MB E350 doesn't have a block heater. Do you guys use regular anti-gel additive? Or do you just make sure you only park in heated garages?
After being outside all night, there was a very short delay (1-2 secs.) with the glow plug before start-up. I did not add any anti-gel to the fuel tank.
I have not yet read of any winter start-up issues with the E350BT in cold conditions.
No block heater needed. No additives needed. No delay starts. Drives no differently than my gas vehicles. I just press the start button, car starts normally, a very short "warmup" (a few minutes) and off I go.

Anyway, I think the gel point of #2 is much higher than -30C and the fuel doesn't care what kind of car it's in. It's possible that they add the anti-gel before you pump it in Canada (and maybe here too).
Thanks for the info - much appreciated. Sounds like something I don't have to worry about.
That said, the coldest I've personally ever driven my 1979 240D was ~25F. The glow plug light took quite some time, but she did start, and that's 1970's technology. Some 35+ years later, the situation's MUCH better.
Here's a -25c (-13F) cold start on a GL350. Note that the driver didn't even bother to wait for the glowplug light to indicate the 'plugs were up to temperature:
Here's what happened earlier this year.Arrived in Val d'Or about 6PM.It was about -30F.My tank was almost empty so I went to a nearby Shell station and filled up.Got to the hotel and was in for the night.The car sat from 6:15PM until 7:30AM next morning.No garage...battery charger...block heater...or fuel additives (*never* used additives because of warranty fears).At 7:30AM it was -40F and the car started with *no problem at all*.Of course it sounded like,and handled like,a Mack truck for the first 30 miles or so but....
And my experience with my BMW was identical except that it was only -30F when I started it.
IMO the key factors for starting a diesel in winter is a strong battery and *locally blended* diesel.
Anyway, in the really cold -F, or -30C, the car will take one to two seconds for the glow plug to super heat the fuel before it fires the engine.
That is all. And I have a one car garage that's full of snow blower, lawn mower, etc... so my cars all stay outside 24/7/365.

For Canada it was equipment included within country code 701.
Here's some chatter on the GLK boards about it: https://mbworld.org/forums/glk-class...onnection.html
Again, as I mentioned, it's not a true block heater, it's an in-line hose heater.
As I see this discussion unfold, I'm starting to wonder if I had old summer fuel in the truck when I had my problem. The truck even has a heated fuel filter bowl (which is pretty large), but that doesn't help when the lines back to the tank are full of gelled fuel.

I also had a Smartkey remote starter from Midcity and it was great for cold snowy days. Start the car inside while getting dressed, come out, shovel, clean off the car and it's already warm by the time you get in.
I work in then fuel industry in Calgary, and have an E 250. A few comments...
-Block heaters are generally recommended for temps around 0F, for gas or Diesel engines.
-Block heaters heat the coolant in the block, not the fuel, so if the diesel has gelled in the tank, the block heater doesn't help.
-we've started our E250 at -18C without the block heater and driven off immediately, without issue. The engine doesn't benefit from idling to warm it up.
Diesel is blended to meet the cold weather needs of the local geography for the season. For example, in June diesel may be blended to be good to 0C, but at this time of year, in Calgary it might be good to -30C. Currently in Toronto, it might be blended to be good to -20, as Toronto's a warmer climate.
Generally, your diesel should be good without additives unless you hit really unseasonably cold weather, or find yourself filling up in one area and driving to another much colder zone.
A healthy battery and locally blended fuel is all you need in my experience.
