oil consumption
Do you have any history on the car ?
When was the oil changed ?
Was the correct amount put in at the oil change ?
If your not sure I would just change the oil and filter it takes about 9 qts of Mobil1 0-40.




The dealer out here wanted $1600 for a spark plug and wire change on my clk55

The level sensor could be failing but you would not know without draining and measuring the oil that was removed from the engine.
I average around a half quart usage in a 4000 mile oil change interval. If you are trying to go the full 10,000 between changes expect the engine to use a bit of oil.
As engine oil collects un used carbons from combustion or moisture from sitting expect it to burn along with the fuel. I am not in favor of a 10k oil change at all especially when the car makes twice the power and torque of others. If you love that power then protect the internals by reducing the interval to 4k after the engine starts seasoning. 80k
I perform my own oil changes and pour the used oil back into the empty container taking note of low level.
I am approaching 200,000 and have light leak around the level sensor and minor smoke in the AM which is likely a valve guide seal.
Cheers
