92 300CE -eats oil, 50 miles per quart
Hi everyone,
My baby just developed a appetite for motor oil recently. No leaks, just a faint smell of burnt oil occasionally while motoring. Any advice on where and how to look for the problem is greatly appreciated. |

Do a search for valve guides and / or valve seals.

Two more questions: 1. How many miles in the engine? 2. Have you recently changed motor oil weight/brand? 3. What kind/weight motor oil do you currently use? (OK 3 questions. )

And I thought, my oil consumption of 1 quart per 1,500 miles is bad but 50 miles per quart? the car must use oil instead of gas? If you don't use any gas then it is a good 200 mpg car, 4x better than a Toyota Prius with the annoyance of more frequent fill-ups

Tex, Enrique told me that 1 qt of oil per 2k miles is OK.
What weight oil are you using? I use 20-50, which is what the manual says to use. My 300CE uses a little less than 1 qt per 2k miles. The 300TE with the M103 engine and over 210k on the clock uses less than 1 qt of oil between oil changes (3k to 3.5k miles).

I just had the oil changed a week ago, 3K miles after the last one. According to the bill they at Firestone used Kendall GT1 10W30 full synthetic, I trusted them to have it right, now I need to check the manual.

Try 20-250W and see if oil consumption does not drop for your car.

Yes, Texas does have some colder days than California. So I assume 10W30 is fine, but next time I'll try higher weight, not in winter of course.

You could be using 5w-20 for all I care, one quart per 50 miles means you've got a problem. Get a compression test done on each cylinder right away.

Check your owner's manual first though.

Has your car always had fully synthetic oil?
Look like valve stem oil seal time.. |

Yes, it always has had fullsynthetic oil as long as in my possession.
You may be quite right, yesterday I got the car tuned up by David S Poole, also a member here, and he mentioned the same thing, although he added that it is not pressing, so I am going to do it at next service interval.

Change or your valve stem seals soon, or you will soon ruin your catalytic converter also if it is not ruined yet. A good MB mechanic should be able to do this without dismantling the engine, it is not an expensive job at all and your oil consumption will drop significantly after this.
