Step-by-Step Instructions:

Locate Oil Filter:

Remove the cap, revealing the oil filter beneath. The filter is situated near the oil dipstick tube.

Prepare Evacuator Pump:

Utilize an evacuator pump by inserting the vacuum line into the dipstick tube until it stops. Give it a few pumps to start draining the oil.

Remove Plastic Cover:

Lift the plastic cover surrounding the oil filter. Simply pull up on the sides to reveal the dipstick tube.

Oil Filter Removal:

Remove Air Intake Hose:

Disconnect the air intake hose and remove the push pin securing it in place.

Use 27mm Socket:

Employ a 27mm socket on an 8-inch extension with a half-inch ratchet to turn counterclockwise and remove the oil filter cap.

Drain the Oil Filter:

Lift the cap slightly, allowing the oil to drain. Carefully pull out the filter, ensuring minimal spillage.

Replace O-Rings:

Replace the old filter with a new one, equipped with fresh O-rings. Pay attention to their correct placement.

Install New Filter:

Attach the new filter, ensuring it clicks into place. Reinstall the cap, turning it clockwise until it's snug.

Refilling Oil:

Refill with Oil:

Choose a suitable oil, like Mobile 1 0W-40, and pour approximately 7.5 quarts into the engine.

Check Oil Level:

Verify the oil level using the dipstick. Keep in mind that after starting the engine for 15 seconds, the oil level may adjust between the max and min marks.

Final Steps:

Clean the oil cap, reattach it, and replace the engine cover. The oil change process is now complete.

Remember, maintaining the correct oil level is crucial, so avoid overfilling. If you follow these steps diligently, you'll ensure a smooth and effective oil change for your Mercedes-Benz C300. Happy driving!
