Determine oil consumption - AR18.00-P-0025-05MM

WARNING: This page does not describe the selected car, but rather 33 other vehicles, including the 2016 Mercedes-Benz E63 S AMG, 2016 Mercedes-Benz E400, 2016 Mercedes-Benz E350, 2016 Mercedes-Benz E300, and 2016 Mercedes-Benz E250. However, it is still accessible from the selected car via links, so may be relevant.

ENGINE 152.9, 157, 176, 177, 178, 276, 277, 278, 279 

ENGINE 256.9 

ENGINE 271, 272, 642, 646, 651 

Weigh engine oil 

  1. Drain engine oil and catch with the oil reservoir provided.
  2. Place oil reservoir on a balance and weigh.
  3. Note engine oil mass in kg and kilometer reading for the vehicle.
  4. Pour engine oil into the engine.
  5. Determine oil consumption 

  6. Perform measurement run.

    IMPORTANT For a measuring drive undertaken by workshop personnel the test course is 250 km taking into account use of vehicle by customer. For a measuring drive performed by the customer the measurement distance is 1000 km.

  7. Drain engine oil and catch with the oil reservoir provided.

    NOTES To prevent measurement errors, the new measurement must be carried out at the place of the first oil measurement and with the same oil reservoir. Measurement errors can occur otherwise.

  8. Place oil reservoir on a balance and weigh.
  9. Note engine oil mass in kg and kilometer reading for the vehicle.
  10. Calculate the difference in mass of the engine oil.

    IMPORTANT The difference in mass is calculated by subtracting the engine oil mass after the measuring drive from the oil mass before the measuring drive.

  11. Calculate measurement distance.

    IMPORTANT The measurement distance is calculated by subtracting the kilometer reading before the measuring drive from the kilometer reading after the measuring drive.
