Adding 1 quart of oil to 2005 C230 Kompressor sedan
Last night, I got a warning message that I needed to add 1 quart of oil at the next gas station. Shortly after, I stopped at a Chevron and bought 1 quart of Chevron Supreme motor oil (ISOSYN), 5w-30, and added it in.
My Service B was 7,000 miles ago, and the car was serviced with 5w-40 Kendall GT-1 synthetic.
Next Service A is in 6,100 miles.
Should I keep plugging along until the Service A, or get an oil change now?

Just do what the computer says. Even though I don't know you, I can assure you that the engine knows what it needs better than you do.
7k before adding a quart is nothing to be too worried about, imho.

If you burned a quart of oil already, I would take the car in ASAP and find out why. That's not right. I just got the same message on mine, but my service is coming up in 900 miles, so I'm not worried about it.

As Tommy said - do as the computer says and don't think too much into it.
I have burned 1/2 quart so far and I have 4,000 miles till next service.

Well, treat your car as you will... I personally won't take a quart of burned oil, half way till the next service as 'Normal' wear and only heed the warnings of the computer. That's just being naive. I would want to know why my car is burning more oil than it should be. Better to be safe than sorry.

Just a little addition to my last post, burning oil faster than normal is a symptom of *possible* serious problems brewing:
bad or worn valves (seals/guides), pressurized crank case, or blow-by from worn pistons. I already had a valve job and the head replaced on my C230 at 34,000 miles... so I'd be a bit more cautious than most... because it's a freaking expensive fix. Don't wait for your computer to tell you that your car's f*ck'd up.. that's just stupid advice.. sorry.

I don't think this is the cause of the oil consumption but FYI, neither of those oils are 229.5 approved oils. The Chevron Supreme Synthetic is, but only the 5w-40. Kendall GT-1 in 5w-40 meets 229.3 spec, so if your car is an older C-class I guess it is ok.

I wouldn't call a quart of oil (assuming that it was originally fully topped off, of course) in 7k to be that much out of spec, and MB doesn't, either.

Ahhh the good old Oil Consumption issue. My car doesn't burn any oil at all it drinks it 
Maybe your car and my car should meet up for a couple of drinks (my car will outdrink your car-my car is the one on the right)
On a serious note, I think you are fine. Since you added a quart measure the oil see how much you got in there. Maybe you were low to begin with
My car loves to drink oil and the dealer did an oil consumption test and said by the time my interval is over I will have to add 3 quarts of oil
So you are fine (for now)

This is really nothing to worry about. People are just so dramatic about it.. almost as bad as they are about octane. The car could have been low from the last service.. I wouldn't concern myself with it unless it becomes repeatable - and even then, 1 quart in 7,000 miles is well within MB specs.
Use 229.5 oils for future reference. Mobil 1 0W-40 Euro Car formula is an excellent choice.
Edit: Also, use dyno mode and check your level. It should say 5.5L (5.8 quarts).

Just to make clear - I've added 1 quart of oil as the computer requested (Chevron Supreme). The oil weight doesn't match, and I'm not sure if the Chevron is true synthetic based on some Google searching.
Should I get an oil change right now, or wait until my next Service in 6,000 miles?
Is that 1 quart of different weight oil that I added going to cause damage?

Chevron make Chevron Supreme in a fully synthetic & the ISOSYN version which is just a Group II ISO dewaxed product from the Richmond refinery. Still a very good product but does not meet 229.5 - was never designed to.
Relax. As long as you did not put gear oil etc in the engine you are fine.

It's always good to keep an extra quart in the car, in case you need one. Not all gas stations sells the same brand or wts of oil for your car.
off topic...Not sure about this...but my MB mechanic have advised me to change the oil every 5K and not wait 10K. (Synthetic Mobil1 5w-40.)

That's too early isn't it? (half the interval)

Mobil 1 5W-40 does not meet Benz Benz 229.5 HTHS. Karo - even in torrid zones like SA Benz recommend 15,000Km - You could drop drain to 10,000 miles but not less than that. Especially with a fleece filter.

I questioned them about the oil wts... I guess a bulletin from MB was sent out to MB shops to start using synthetic Mobil 1 5-40 with the exception of AMG vehicles. Have you guys heard about it?
