Burning Oil

Burning not leaking? Is there white/blueish smoke from tailpipe? And how many miles can you get before having to add a quart? These things can help me form an opinion to your question

I'd say after about 2-3K after an oil change the oil light comes. It's not leaking at all and no smoke coming from the tailpipe. Thanks so much!

Only 137000 miles? It's hardy broken in. Are you thinking the valve seals, rings or just what it is making it lose oil. F.N. Is right. We need more info. Did you get an estimate on repairs?

To state the obvious, it's gotta be going somewhere. Give me some time for research. I want to figure this out.

All I can find is valve guide seals, badly leaking and when you first start it up you don''t see the smoke, it will come out in a big puff then be almost un-noticable. The PCV, Positive Crankcase ventilation, could need a new valve, especially if the rings are starting to wear and blow-by is pressurizing the crankcase and PCV is pulling oil out and being re-combusted, therefore less smoke. Check your air filter to see if it has oil on it..that's a clue it is the PCV. Throwing guesses both wild and from information from forums

All terrific responses, thank you! I've yet to find a mechanic that I feel is trustworthy and on mark. I did get 3K from one without seeing, he referenced the valves needing to be replaced. I'll have a discussion with one that is pretty good, but it's always better to know prior to walking in. And I know things are changing, but as a woman I sometimes feel like I'm always getting the best answer from a mechanic. I'll check the filter. I remember looking at it at the last oil change, it was dirty but I'm not remembering seeing oil. It's a small shop so I will ask, they might remember. I've heard that this car should take me many more miles, and I hope that's true! They just don't build them the same!

Until you get this issue resolved, when you add oil - do not use synthetic. It is much thinner and will burn/leak quicker. As for 137k miles - if it has been taken care of, it will probably last a lot longer. Assuming your MB is well maintained, the engine and tranny may last forever. In a MB, its all the other "stuff" that goes bad - so much electronic gadgetry.

Got my transmisson rebuilt road down the street and abig gust of smoke came out the tail pipe 2005 e 320 mercedes

What color smoke? How long had the car been sitting without being driven? How many miles are on it?

I have Mercedes Benz E320, and burns oil, I steam the engine and I don't see any leaking

what can cause this ,, my e320 bluetec mercedes starts to consuming lots of oil

Following this. Have a very clean good running 2004 that’s using a quart every few thousand miles but runs very well, no smoke, dry undercarriage and engine compartment.

mine is staring to burn oil too. I feel depressed. I love my Benz

mercedes 350 E burning oil every 500 kilometer i put in 1 liter i change pcvalve and plugs but still burning, the enjine is still strong have lots of power and acceleration Please advise

My 2011 ML350 Bluetec didn't burn a drop of oil until I passed the 100k mile mark. It's gotten worse, and worse: I am adding a quart about every 800 miles now. I tried Lucas oil treatment (one standard quart and one synthetic) and nothing changed. Zero smoke, lots of power, and hasn't thrown any codes or clogged the DPF. Now I'm at 118k miles and it's had at least 8 quarts of additional oil between 6k oil changes. Dealer looked it over and had no explanation. I paid big $$$ for a new oil filter housing, PCV, and EGR and it made zero difference. I'm thinking it must be the turbo or rings, or both.
