I've got an 07 ML320 CDI and I also get stunning MPG. On a recent long trip to Cape Cod with a loaded SUV I got 26.5 and that was doing near 80, I divided gallons used into total trip miles when filling up.
 
In winter Diesel is higher but in summer it is much lower, less then regular in some cases. Keep in mind Diesel in winter is around the same price (maybe a little more) for premium which all MBs require. Bottom line, with the extra miles you can go on a gallon and low summer prices you are paying less overall for Diesel. Get one...oh and that torque is intoxicating

It is something that has to be experienced. You can have the gassers HP, I will take the diesel torque any day. How do you like the 7 speed transmission?

The 7 speed is ok but I do get a couple shift kicks if I do strong acceleration and then let off the gas, the tranny wants to go for the high gears ASAP so it will jump 2 to 3 gears if you let it and gives you a double kick. Only happens if I am aggressive then let off the gas (reaching 40 or so). Of course this could be because of the bigger torque causing a snap as I have a CLK with the same 7 speed and do not notice this.
 
I finally found a use for the shift paddles on the wheel. The ML diesel loves to engine brake going down hill or stay in the best RPMs for full torque at lower speeds (gear 4 to 6 at 30 to 40) - to get better MPG I force it to stay in the highest gear with a tap of the right paddle....works fine. I will add that auto engine braking when coming to a full stop is great benefit - love that subtle growl too.

Help, I just filled up my new 08 diesel with low sulfur and not ultra low sulfur. Should I pump it out? should I just fill in more of the correct ultra low? HELP HELP!!!

My ride is so new I have not even fueled it yet. Hit your teleaid info button and choose vehicle information when they ask and they will have your answer in minutes while you sit in the car. Let me know what they say.
Thanks.

Pump it out! You could seriously mess up your ride if you run it on Low Sulfur Diesel. From what i've heard it'll emit black smoke and u'll hear the engine chug followed by the engine potentially breaking.
 
Low sulfur has 550pm and Ultra-Low sulfur has 15ppm so you see the difference.
 
I haven't filled with low sulfur yet cos i'm really careful not to- don't wanna risk damaging the engine and I think you definitely shouldn't try to run on low sulfur.

I asked my salesmen and he said it's a new car and it's ok, but don't make the mistake too often. I was hoping anybody have more information. Somebody like a mechanic or similar profession.

What I've heard is it can clog the special exhaust system, MB will not warranty it if that happens. The system is $1500 or more. those 550ppm and 15ppm numbers mean parts per million, so imagine 550 particles getting filtered through your exhaust system all at once vs 15 particles - not wholly accurate but you get the idea.
 
You may be ok as it is a new car and the system is clean...but go ahead and get the ultra low in there to start and dilute
 
good luck

Low sulfur diesel can be anything from 30 PPM sulfur to 500 PPM sulfur. If you are in CA it is no more than 130 PPM. You can drain it and sell it to someone with a diesel PU truck which all run fine on the stuff.
