I was in an AddLee W213 the other day, the driver said this car was using about a litre of oil every 5000miles. This seems very high to me! Apparently all the Addlee drivers of W213s are having similar issues. This is why MB are over filling the engine oil to it's absolute maximum, in an attempt to stop the engine oil level going below minimum level before the service indicator pops up on the dash. Anyone else having a similar issue?
