how much oil does your w210 burn?
Others have found that running crappy oil for years causes ring sticking problems and elevated oil consumption.
However, I would not be terribly concerned with 1quart in 4k miles.

Go see your local dealer, they should know.

Do you drive short distances?
Do you drive a lot of stop and go?
Do you accelerate liberally?
If you answered yes to any of the questions above, then it shouldn't be a big deal that you're burning a bit of oil.
PS: My car does not drop one drop of any fluids of any kind EVER! I believe this car is possessed!

valve seals
piston rings
first would be of course to check for all leaks, head gasket, valve cover gaskets, etc.
another thing with high mileage, could try a higher viscosity oil to see if it still burns oil, before tracking it down to valve seals, piston rings....
also a good Seafoam treatment might help

I have 105k miles on it and am at about 4k miles on the last oil change. I do alot of highway cruising and very little around town driving in it.
I was up in Boston this weekend and the highways were clear, so figure 75-90 mph for 5.5 hours in each direction. about 30 minutes from home after driving 5 hours straight my car popped a "Oil at minimum level" messsage. Never seen it before. Stopped at a rest stop for 10 minutes and when I restarted the car the message was gone and did not reappear for the rest of the drive.
Thoughts? Recomendations?
