Mercedes ML320 How to Change the Oil and Filter

1. Park the car on a flat, level surface. Set the parking brake.
2. Locate the oil pan underneath the car. The oil pan is located at the bottom of the engine. Slide a drain pan underneath the engine to catch the used oil.
3. Unscrew the drain plug with a socket wrench. The drain plug requires a 13mm socket. Allow all the oil to drain from the oil pan (allow at least 10 minutes for all the oil to drain adequately). Tighten the drain plug to the oil pan with the socket wrench.
4. Open the hood to access the engine compartment. Locate the oil filter cap at the front of the engine. It will be positioned directly in front of the oil-fill cap.
5. Loosen the oil filter with an oil filter wrench. Pull the oil filter out by the cap. Ensure you have a pan to catch the excess oil dripping from the filter. Pull the old filter off the end of the stick, using an old rag--this will prevent from making a mess.
6. Insert a new filter onto the stick, pushing it in until it stops. Insert the filter/cap back into the oil filter housing. Screw the cap tight by hand.
7. Unscrew the oil cap located directly behind the oil filter housing. Pour in seven quarts of engine oil. Pull out the engine oil dipstick located by the oil-fill cap. Wipe the dipstick clean. Insert the dipstick back in to the tube. Pull out and verify the level. The level should be between the minimum and the maximum marks on the dipstick. If the level is below either of the marks, add additional oil in half-quart intervals. Check the level each time you pour the oil.
8. Start the car up and allow it to idle for five minutes. Turn the car off and let it sit for an additional five minutes. Check the oil level once more. Add more oil, if necessary.
9. Log the number of miles driven and the date the oil change was completed. Reference this for the next oil change interval.
