2004 clk55 using oil

[sajid bashir]

hi i have a 2004 clk55 converti with 90k miles, i had it serviced recently with gen merc oil 5w/40 and it asked for a litre of oil after 2 weeks or so i thought maybe the mechanic put in less on the service so i topped it up with a litre now after 200 miles or so it came up with the same message yesterday. i cant see any oil leaking visibly, is this normal for this type of engine, there is no blue smoke on start up in the morning, some mentioned using 10w/40 its better bit confused now any ideas guys?

A litre in 200 miles is not normal and suggests a serious leak or consumption issue.

 

[sajid bashir]

Any ideas on common places where oil could be leaking, also is the oil grade correct?

 

[sajid bashir]

Or would the car have a faulty reading?

 

[LostKiwi]

If the oil is the correct MB spec (229.5 or 229.51?) there should be no problems with it.
That will be an M113 engine I think so the only common source of oil usage is blocked breathers on top of the cam covers or leaking cam covers (or both - blocked breathers can cause leaks).

 

[sajid bashir]

So does dies oil leak from the breathers? Or does it burn out through the exhaust

 

[LostKiwi]

The breathers vent into the inlet manifold. Any oil will be burnt by the engine.

Do actually check the dipstick (or get one if not fitted) as the sensors do go faulty sometimes.

Mine is the 2004 CLK55 AMG it hasn’t got a dipstick you check it electronically if I get a dipstick where can I get one from and how does it work to check the oil?
