I had it diagnosed and the repair was to replace the valve covers and gaskets and reseal the baffles. After 2000 miles I had to put 2 quarts of oil in it again the other day (check oil level light came on). I have never had a burning smell, just warning light and then low reading when I check the level. Now they are telling me it's not unusual to have to add a quart or two of oil, especially with highway driving. It had never happened before these last few months. The car has a little over 107,000 miles on it.
Why would I start burning oil for the first time ever in the last 3-4 months? on 2001 Mercedes-Benz E320
manf say approx 1/2 qt per 1k miles is ok after 100k miles on car. who is telling you this is normal?
My repair shop. But that would be about right. I've put close to 4000 on it since my last oil change, so I guess 2 quarts would be acceptable. I just hate to assume it's normal then find out 6 months from now that I've done major damage to the engine. They quoted the mfg as well. And they said that engine is an oil hog.
I dont think this is normal,,its not just ring ware,,,i have a 2001 e320 with 150.000 miles it does not use this much,,it will run about a quart low between oil changes,,check the pcv valve,,
