"229.5 engine oils must be used with fleece oil filter when used with the Mercedes Maintenance System (MY2005+) in M112, M113, M272 and M273 engines. With FSS paper filters are fine."
"229.51 is only approved for diesel engines."
Because I just changed my oil last week and put in part 0-40 and part 15-50 and my engine definately feels sluggish. I didnt realize how much of a noticable impact oil weights would have. Now I'm wanting to swap to a 30w pennzoil, quaker state, or castrol european formulas. Would any one be fine? Recommendations?
Just a little extra info, engine temp peaks around 90oC , mileage is 103k

Check the packaging of the oil & make sure it holds 229.3 or 229.5 approval. 'Don't use anything that says "meets the requirements of". That is oil company BS for "is not approved."
Does your car use any oil?
I can't comment on the sluggishness you describe - you don't give proportions of your mix. A 15W-50 is pretty thick stuff even at operating temperature. Don't mix viscosities if you can help it. It won't damage anything but if you were sampling it would show strange results. You will also use more fuel with a 15W-50.
If you really feel a noticeable difference in the car just make darn sure that you have not over filled it.

Oh and I forgot to tell, I only could suck out 6.7 liters, no more was left. I was kinda scared if it was running on too little oil but I did the check oil level many times before the change and it said it was ok.

If you take oil out of the drain plug you might get more out. My car only has 47,000 kms on the clock & appears to use no oil. Never been topped up between services.
Anyways, I went to dyno mode and sucked out oil back to 6.7/8 liters. It feels kinda bad knowing I drove 66 miles today with 2 liters of oil over what I should put. The idle sometimes went over 1000rpm too. If it weren't for this post I don't know how long id have that oil in there :P
Also when I took out the oil, it was near the same black color as the oil I had before the change
. I recently bought the car so I don't know when the last oil change was. I just relied on the "Service A in x miles". Should I change all the oil again? I have about 100 miles on this new oil and its pitch black.

Today's highly detergeant oils discolour very quickly as they take combustion contaminants into suspension. Your engine is probably a little dirty internally - you don't know the car's history. I would leave the oil in for 3 to 5000 miles & then change it early for a 229.5 product with fleece filter. Reset the service system & go back to recommended oil drain. This will give the engine a good flush.
I used the Fram filter that it reccommended, CH 9918. I figure that if they know the syntheic oil is to last 10,000 miles then so should the filter.

MB 229.5 sulfated ash has to be within 0.8 and 1.5
MB 229.51 sulfated ash has to be max of 0.8
These specifications are now in direct conflict with one another. What this means is:
One product for MB passenger car Gasoline.
Another product of different formulation for passenger car Diesel.
Don't let anyone tell you that their product meets both specs as we have warned before. It is now official.
