Changing the Oil and Filter
on the ML350

Oil and Filter Change Intervals
Mercedes recommends changing the oil and filter on the ML350 every 13,000 miles when using the factory recommended synthetic oil and the fleece oil filter.

Type and Viscosity of Oil Mercedes is very specific on engine oil type. Engine oil must satisfy many different industry standards and manufacturer requirements. The most common oil ratings are:
API - American Petroleum Institute
ILSAC - International Lubrication Standardization and Approval Committee
ACEA - Association des Constructeurs Européens d'Automobiles

Tools and Supplies Required for Oil Change
Filter Wrench
Vacuum System for Oil Extraction
Fleece Oil Filter
8 liters/8.5 Quarts of Oil
Changing the Oil and Filter
Ensure your car is operated to normal operating temperature before starting the oil change. This allows the engine oil to flow freely.
This procedure is based on using a vacuum system for oil extraction. Because the oil filter is at the top of the engine, this is a very easy method. You can also remove the belly pan and drain the oil from the drain plug.
Remove the engine cover by lifting the forward side up and then pulling it forward.
Insert vacuum tube into dipstick tube location.
To use the vacuum system (I have a Mightyvac MV7201), insert the vacuum tube into the dipstick tube location until it stops. Connect the tube to the larger diameter tube and connect that tube to the Mightyvac. Ensure the valve on the side of the Mightyvac is in "evacuate" and pump it approximately 10 times. It will pull a vacuum in the chamber and oil will flow out of the engine and into the storage canister. You can only pull a certain amount of vacuum on the unit, it has a relief valve for pressures (vacuum) above that.
It took about 20 minutes for the oil to completely be pumped out. You'll know when it's done when it starts sucking air and making noise. You can hear it.
Remove the oil filter by using an oil filter wrench on the housing. See following pictures for more information. Once the oil filter and o-rings are replaced, fill the engine with 8.5 quarts (8 liters) of new oil. Start the engine, turn off the engine, check the oil level, adjust as necessary and you're done!
