ML 350 BlueTEC-Fuel Additive Question
I am about to buy a ML350 BlueTEC, and have a question about adding an anti-gelling agent to the fuel tank in the winter. On my VW diesel I always add Cetane boost in the winter to prevent the fuel from gelling. I have asked at the MB dealership, and was told that MB recommends you NOT add anything.
I called MB USA, who said they would get back to me, but have not.
I understand about about the Ad Blue - but that is post ignition cleaning and does not help with cold weather starts and the fuel line.
Do BlueTEC owners routinely add to the fuel in the cold months?
Thank you.

I checked with my gas station, and they do switch to winter diesel. The 350 owners manual says the line is heated - or something like that - so no additive is necessary. Hmm, now I just don't know. I suppose it wouldn't hurt to add it in the winter, right?

One winter my CDI was parked outside for 3 days at -30F (-34C) and the fuel gelled up and it wouldn't start. I had to use a hair dryer on the fuel filter for about 30 minutes, then it fired right up. If the newer ones have heated lines that would be a great improvement. For me, I use Power Service Diesel additives year round, and have never since had an issue.
Now on a separate note, I have heard of Bluetec owners having their Adblue freeze up fooling the vehicle to believe the Adblue tank is empty, and the ECU restricts the vehicle from starting. Not sure if there is a fix for that yet.

I used the same additive in my VW diesel - which I just sold to the dealer. I also gave them all of the additive, thinking it was not needed and because I thought it would be difficult to dispose of. Oh well, I will go and buy some more.
I had not heard that about the Adblue freezing.
