Question about 2005 Mercedes-Benz Mercedes Benz E320 Cdi
You may not be 'burning' the oil, it could be lost because of leaking gaskets.
If you do not have bluish fumes under hard acceleration or see a puff of smoke after idling down a long grade and resuming acceleration, the oil loss could be elsewhere.
Make sure you have no spotting on the ground under the engine after standing, and examine the engine itself for signs of wet oil deposits.
You didn't mention the odometer number so we cannot determine whether this oil loss is due to engine wear. Diesels can actually consume some oil passing the rings since they burn a heavier fuel than gasoline engines and this can mask some blow-by occurring from wear. A compression check might be in order if you find no traces of oil loss elsewhere.
