Dr. Diesel is 100% correct. MB has set specific criteria that must be met in order for warranty repair work to be performed to remedy oil consumption. However, russrite should have his dealer begin the process of an oil consumption test. This involves performing an oil and filter change, and re-setting FSS. From that point on the oil consumption can be monotored and documented by the dealer. If the rate of consumption reaches the maximum allowable rate the repairs can most likely be done at no charge. At any given time, there's at least one car in my shop getting re-ringed due to excessive oil use. You'll never know unless you ask.

Dr. D, you're far more understanding than I am concerning deanyels' comment. I take offense when an uninformed member makes a blanket statement about MB dealerships/personnel. Maybe some Forum members don't realize that some of the MOST HELPFUL people on this site are employed by MBUSA or dealerships.
