I own a 2002 E320 with 134,000 miles. The car has been scrupulously maintained and all service requirements faithfully met. My problem is that it uses about a quart of oil every 750-1,000 miles. My garage floor is clean as the proverbial whistle so it is doubtful there is a leak. Is this normal?

 

Hi! What kind of oil you use? I think the car is 'eat' the oil when the oil is too 'thin' or slight. The best the 5w-40.

 

Thank you very much for this information. I really had not thought about that. I have been using 5W-30; I will change to 5W-40!

Thank you!
