* Engine Variations: The E220 CDI has been produced over many years with different engine variations (different displacements, years, etc.). Each engine may require a different oil capacity.
* Specific Model Year: The oil capacity is highly dependent on the specific year of your E220 CDI.
* Oil Type: The type of oil (e.g., 5W-30, 0W-40) can also influence the amount required.
How to Find the Correct Oil Quantity:
1. Consult your owner's manual: This is the most reliable source. The manual will clearly specify the exact oil capacity for your specific model year and engine.
2. Check the dipstick: Your dipstick will have markings indicating the minimum and maximum oil levels. If you need to add oil, you can use this to guide you.
3. Contact a Mercedes-Benz dealer: They can provide the correct oil capacity for your vehicle based on its VIN (Vehicle Identification Number).
Important Note: Always use the correct oil type and quantity as specified by the manufacturer. Using the wrong oil or exceeding the recommended oil level can damage your engine.
