When I get to putting the Webasto in I’ll try to grab pics and make a thread.

I am often puzzled reading this stuff on hard starting diesels. I can only assume the US fuel is crap. I use 15-40 oil year round and I never plug my truck in unless it gets down over -25 C. I have been doing this since 1992 and have seen no reason to change. Last vehicle was a 1996 Dodge, kept it for 11 years, this one is a 2006, and have been driving since 2012 on it.
When some one has unplugged me to plug themselves in, I have started my truck at -32C with a murderous wind. Did 2 preheats to be sure but it fired right up.

My older tech engine, the 1982 Mercedes 300SD, my wife's daily driver, has to be plugged in at -10 or else it won't go, but we have my truck to fall back on if she makes a mistake.

When I had a Ford SD diesel, it had to be plugged if it got down to -15, but that was ok.

It seems to me that these additives and such do more harm than good. When I was driving on the ice road, my traveling companion had a Volvo with a miss, and kept pouring in that crap into his tank. I kept telling him he had a leaking injector pumping combustion gas into the common rail(I was right) and eventually it quit at the BHP Diamonds site. The thing was dragged into their shop, they drained the tank, and put in fresh fuel, fired it up and backed out the door.
I forgot which additive he used, but it claimed to "disperse water"....the last thing I want is dispersed water entering my injectors

Edit:
I think light oil is a good thing for starting up and running to the store for a pack of cigarettes, but for me, that is a 90km(60 mile) drive in which my engine is warm and working at 70mph highway speeds for an hour. Light oil is a nasty thing for an engine working hard plowing smow or pulling a heavy loaded trailer in any weather.

What viscosity grade oil is in it now? What do you think 'thin' oil is?

If you have 15W-40 in it today and it is not starting, you have another
problem and it is not your oil. 5W-40 would be easier to start but again
15W-40 at 0°F is not your issue.

No need to assume, it is crap. ULSD is even harder to start in the winter.

Do you guys in the great white north run straight #1 diesel fuel in the dead of winter?

In what we consider the GWN, north of the 60th parallell, you can still purchase fuel as P40 and winter diesel as P50...P is pour point.
P50 is what we can buy as stove oil for the pot burner oil stoves by the drum.

In the south, such as where I live, the diesel fuel is seasonally adjusted, it is continually tweaked as per the average normal temps for the time of year.
A skid tank of fuel bought in July will not make you happy if you burned it in January.

I am using US nomenclature.
#1 diesel has a pour point around -40°
K-1 Kerosene has a pour point around -50°C

So in the GWN looks like summer diesel is what we call #1 and winter
diesel is a kerosene cut but with the additives that are needed in fuel,
pour point depressants, detergents, lubricity additives, anti-gels, etc.

Thanks for the info.

Here in Illinois they have summer and winter blends for fuel, there is
the southern zone and the northern Zone. For gasoline they allow more
butane in the fuel in the winter, which generally drops the price a bit.

Diesel in the summer is straight #2 for better mileage and lower cost.
Winter diesel is a blend generally a 50/50 blend if you get bio free fuel.
If they run bio then more #1 than #2. But it varies, and you gamble
buying pump fuel. I have a good local supplier.

Yes, 15w40.
The last thing that is an unknown is the injectors. They have been on my radar for a while but may have been bumped up a few levels. New injectors made a huge difference in my deuce, I guess ill go ahead and bite the bullet.

You need to have the injectors tested before you just buy new ones. They are likely weak but don’t just count on it.

Yup

I have a pop tester and will check them first.

I would look at your compression also.

Our local farm fuel supplier stops with the bio on Nov. 1 each year to favor the "winter blend"
