Measuring Oil Consumption Based On Volume Measurement

Information 

Oil consumption based on volume measurement can best be measured during an oil change.

1. Find out about the driver profile, driving conditions, condition of the vehicle, and so on (see above - interview, test drive, make enquiries).
2. Record the mileage, VIN and measurement date.

   Determine original quantity by recording the oil change refill quantity => 

3. Perform a complete oil change including filter.

   Drain engine oil when it is at operating temperature  (at least 80 °C). Make sure that the oil-filter housing is completely empty (wait 15 minutes).

4. Determine amount of oil to be filled in (new oil) to the exact millimetre and fill it in (at room temperature of approx. 20 °C). For instructions on changing oil, see → 170117 CHANGING ENGINE OIL AND OIL FILTER  or → 170117 CHANGING ENGINE OIL AND OIL FILTER ON DFI ENGINES 
5. After the customer has driven the vehicle for several hundred kilometres in the course of day-to-day driving, check engine oil consumption in accordance with the following steps.

   Determine oil consumption by measuring the remaining oil quantity => 

6. Record the mileage, VIN and date.
7. Drain engine oil into a clean collection container when it is at operating temperature  (at least 80 °C). Make sure not to lose any oil (measurement error!). Make sure that the oil-filter housing is completely empty (wait 15 minutes).
8. Let the drained oil cool (room temperature of approx. 20 °C as for first original measurement) and measure the exact oil quantity (in millilitres).
9. The difference between the original filling capacity and the amount of oil you have just drained, depending on the vehicle mileage, gives the oil consumption in kilometres.
