I use the Power Service White diesel additive when it goes below 32 degrees and do not have gelling issues.

I met the guys from Power Service (they had the booth next to me at SEMA) and several of them use Bluetecs and CDIs as their sales cars. They use their own products in their cars, I use them in my CDI all the time with no issues but that car does not have a DPF.

What does have a DPF are all diesel trucks after 2007 and they approve their product for use in those trucks. Mercedes developed ad-blue technology and its the same as whats in Dodge, Ford, Chevy diesel trucks. If its not killing those trucks, it won't kill you Mercedes. But it could be worth a call to Power Service directly to put yourself at ease.

The products are all now factory endorsed by Cummins as of this year, who uses DPFs.

That's the one. At 32°, there's nothing to worry about with regard to any gelling of fuel. Would suggest OP refers to his particular diesel's Owner's Manual, as the information therein will answer all his Qs. My 300's OM, advised using up to 50% kerosene.

I think it's crazy you are having problems with fuel gelling.

I regularly drove a 300D and had her sit outside in regular single digit weather in the mountains of central New York with nothing more than regular old diesel from a Hess station.

Run the car down to near zero and find a better fuel station. It sounds like you have some old summer diesel stock.

When I lived in NJ, I would cut my diesel 50% with white kerosene or brown if I couldn't find white and it wouldn't gel even at 5 degrees!

I've been driving various MB diesels in New England winters for the past 12 years. As I noted in another thread, yesterday was the very first time I experienced fuel gelling. My best guess is that the diesel used to fill the tank in early December wasn't capable of handling this brutal cold. Filled up tank yesterday, added some Power Service, started and ran perfectly at -3F this morning.

Yes that is entirely possible with a mechanically injected Diesel fuel system in your older 'Benz, but NOT with the newer electronically injected common rail Diesel engines.

The important factor is the fuel filter. Some interesting reading on this subject:

CFPP vs PP in Diesel Fuels

https://www.bp.com/content/dam/bp-country/en_au/products-services/service-stations/downloads/Changing-Diesel-Fuel-Properties-Using-Additives.pdf

https://www.infineum.com/media/80722/wdfs-2014-full-screen.pdf

FWIW, I think that temperatures of -20 we've been having in the NE would be challenging for any Diesel, no matter what additives you throw in the tank. According to the last document above (p 136), the average CFPP (Cold Filter Plug Point, the temperature at which filters are blocked) for the US east coast is -4F (-20C). Even if your additive can take that down by five or ten degrees F (big if), you'll still be plugged at -20. Before you protest, there is variability in fuel quality, which explains the variation in experience.
