Diesel #2?
I noticed that some pumps carry "Diesel #2" ..
Anyone know what is the difference between regular Diesel and "Diesel #2" ?
Is "#2" the same as fossil Diesel, and recommended for the GL-350?

If it is marked ULSD, then it is good (or better, as it is not Bio)
If it is not marked ULSD, then it is not for your GL at all.

I think MB stopped selling diesels in IL, specifically because people were wrecking engines by adding 5%-20% bio diesel blends there..
Googling #2 Diesel -they say it is the same as fossil diesel, but more 'concentrated'. So, it does appear that #2 Diesel is OK for MBs

Thanks N_Jay.. actually, even 5%-20% Bio diesel blends are also marked as USLD (at least in Illinois).

All "road Diesel" is ULSD, both bio and non-bio.
Even the non-bio still has to be Ultra Low Sulfur Diesel (ULSD) to be OK in your MB (No farm fuel)
Bio is not marked "D2".
MB is now selling diesels ion IL.
My dealer (in IL) said he has never seen a problem with a well maintained car, but has seen a few marginally maintained cars with issues.

The newer designation is ULSD as mandated by the EPA has 15ppm maximum of sulfur to reduce emissions. http://www.epa.gov/otaq/fuels/dieselfuels/index.htm
MB has recognized that most states are moving towards biofuels. http://www.mbusa.com/vcm/MB/DigitalA..._Brochure5.pdf
Ultra Low Sulfur Diesel (ULSD) fuel meeting ASTM D975 can contain Biodiesel up to 5 % and certain states have moved over to %5 biodiesel. http://www.scribd.com/doc/96086473/Washington-Plan and here http://www.ct.gov/deep/lib/deep/air/...sel/ulsdfs.pdf
EPA has proposed a mandate to B20 for heavy trucks:

The 'D' weights are D1, D2, or D3. D1 is lighter weight, more volatile, lower pour point (aka "coal oil" or "stove oil" for a really old timer), D2 is for typical on and off road use in engines up to 500 hp. D3 is usually found in marine applications, it tends to be thick and has very high heating values and must sometimes be heated to flow properly in the fuel system. Engines using D3 are NOT designed for frequent starting and stopping. The next heavier grade of fuel oil after D3 is bunker oil for ships. It is almost as thick as tar and flows about as well.

Different context: B2 is 2%biodiesel, D2 is the long time designation for the 'weight' of diesel fuel.

I have never seen B2, just B5
Thinking "B" 2, may be shorthand for D2 with some Bio. (Probably B5)
EDIT:
Looks like I guessed wrong;

There is a B2 fuel.
