1. Prepare your materials: You will need a new oil filter, new oil, an oil drain pan, a funnel, and a wrench or ratchet.
2. Park your car on level ground and engage the parking brake. Turn off the engine and allow it to cool down.
3. Locate the oil drain plug: The oil drain plug is usually located on the bottom of the oil pan. It is often marked with a bolt head or an oil can symbol.
4. Place the oil drain pan underneath the oil drain plug: Position the oil drain pan directly beneath the oil drain plug to collect the used oil.
5. Loosen the oil drain plug: Use the wrench or ratchet to loosen the oil drain plug. Be careful not to drop the bolt into the oil pan.
6. Allow the oil to drain: Allow all of the used oil to drain from the oil pan into the drain pan. This may take several minutes.
7. Replace the oil drain plug: Once all of the oil has drained out, replace the oil drain plug and tighten it securely.
8. Locate the oil filter: The oil filter is usually located near the top of the engine. It is a cylindrical-shaped component with a black cap.
9. Remove the oil filter: Use the wrench or ratchet to loosen and remove the oil filter. Be careful not to spill any oil.
10. Apply a thin coat of new oil to the gasket of the new oil filter: This will help to create a seal and prevent leaks.
11. Screw on the new oil filter: Hand-tighten the new oil filter until it is snug. Do not over-tighten the oil filter.
12. Add new oil to the engine: Use the funnel to add new oil to the engine. The amount of oil you need to add will vary depending on your car's model and engine size. Refer to your owner's manual for the correct amount.
13. Check the oil level: Use the dipstick to check the oil level. The oil level should be between the "Full" and "Add" marks on the dipstick.
14. Start the engine: Start the engine and let it run for a few minutes. This will circulate the new oil throughout the engine.
15. Check for leaks: Look under the car for any leaks. If you see any leaks, tighten the oil drain plug or oil filter until the leak stops.
Once you have completed these steps, the oil level in your Mercedes-Benz C230 will be reduced. Please note that this process may vary slightly depending on the specific model and year of your car. If you are unsure about any of these steps, it is best to consult your owner's manual or seek the assistance of a qualified mechanic.
