Your engine oil is the life blood of your engine. At the bottom of the engine is the oil pan. The oil pan is where the engine oil drains back to. An oil pick up tube in the drain pan draws in engine oil and brings it to the oil pump. From there oil is passed through a filter and then on to the engine. Eventually this engine oil suffers from thermal and mechanical breakdown and needs to be replaced. There are mineral based oils (conventional), semi-synthetic oils and full synthetic oils. Mercedes Benz only recommends the use of semi-synthetic or full synthetic oils in their engines. The ASSYST system in your instrument cluster monitors how the car is driven and recommends service intervals. We strongly recommend changing your engine oil every 5000 miles using a semi synthetic blend and 7500 miles using any full synthetic blend particularly if you drive in a lot of stop and go traffic and short trips. In this tech article we are going to go over all the steps to change your engine oil and filter.

In order to change your engine oil you need to lift up and support the front axle of your vehicle and remove the lower engine splash shields. See our technical article on jacking up and supporting your vehicle and engine splash shields removal for further instructions. Also remember to always wear safety goggles whenever you work under your car.
This picture illustrates the engine compartment.
Figure 1

This picture illustrates the engine compartment. Use your oil filter cover socket to remove the oil filter cover.

Thread the cover out all the way.
Figure 2

Thread the cover out all the way. It will drip oil when removed so turn it upside down to avoid making a mess. This also allows the engine oil in the filter housing to drain into the oil pan. Set the oil filter aside for the moment.

This picture illustrates under the engine compartment with the covers removed.
Figure 3

This picture illustrates under the engine compartment with the covers removed. Locate the 13mm drain plug (green arrow) and remove it.

Be sure to replace the drain plug washer (green arrow).
Figure 4

Be sure to replace the drain plug washer (green arrow).

Install the drain plug back into the oil pan and tighten down.
Figure 5

Install the drain plug back into the oil pan and tighten down.

This photo illustrates the top front of the engine.
Figure 6

This photo illustrates the top front of the engine. You can remove the oil fill cap and add oil there or you can add it through the empty oil filter housing. Adding oil to the engine oil filter housing is faster. Add the correct amount of oil for your engine. This engine takes 8 1/2 quarts.

I will now work with the oil filter cover.
Figure 7

I will now work with the oil filter cover.

Remove the oil filter from the oil filter housing cover by sliding it in the direction of the blue arrow.
Figure 8

Remove the oil filter from the oil filter housing cover by sliding it in the direction of the blue arrow.

Use a pick to remove the O-rings (green arrows) from the oil filter housing tube and replace with new O-rings.
Figure 9

Use a pick to remove the O-rings (green arrows) from the oil filter housing tube and replace with new O-rings. Installation is the reverse of the removal procedures. Install the new O-rings and oil filter in the oil filter housing cover. Install the oil filter housing cover into the oil filter housing and make sure it is tight.

Turn your ignition ON and use the arrow buttons on the steering wheel to scroll to the check oil level function.
Figure 10

Turn your ignition ON and use the arrow buttons on the steering wheel to scroll to the check oil level function. It may take a few minutes before the instrument cluster will inform you if the engine oil is up to level or if more needs to be added. Start the engine and let it run for 5 minutes. Then shut off the engine and recheck your oil level. You may have to wait several minutes before the instrument cluster will display the oil level.

  Followup from the Pelican Staff: Possible wrong oil level or faulty oil filter. - Nick at Pelican Parts  
E 55 V8 KOMPRESSOR Comments: Please keep in mind
E 55 w211
Has 2 filter choices go with fleece for longer oil change interval only use 299.5 oil 0w40 Full Synthetic.

Oil pan has 2 drain plugs front + rear due to split oil sump
Only the E 55 has this and important to keep in mind get all oil out. Don't use vacuum suction u won't get all out on this engine let it drain

Mobile 1 0W40 299.5 most oils today supports 299.3 + 299.5
Longer milage or galon, better engine performance..

Drain plug torque: 30 Nm

  Followup from the Pelican Staff:
I don’t have that info.

I would grab a repair manual. It will have the procedure, special tools and torque specs.

Give our parts specialists a call at 1-888-280-7799. - Nick at Pelican Parts
